Prince George's County Rebanded Frequencies

Prince George's County has been issued licenses for rebanded (radio service code GE) 800 MHz frequencies. See licenses WQKM472, WQKN273, WPBG215, WQKL948 and WQJS954. Some of these frequencies are for the new NPSPAC channels, some are for the COG RINS channels, and some may be for the rebanded legacy EDACS systems.

Mobile Relay Associates FCC License

Mobile Relay Associates, a California-based provider of business-band trunked systems, recently licensed a trunked system in the Washington area. The transmitters are located in Silver Spring (8744 Brookville Road) and Falls Church (8101 Lee Highway). Based on the emission designators on the license, this system will probably be NEXEDGE. No scanner can monitor this digital format.

EagleBank Bowl at RFK Today

The EagleBank Bowl is at RFK Stadium this afternoon at 4:30. Here's what I found last year:

151.6250 [179.9] Unknown
166.4625 [NAC 167] Unknown
461.3875 [ ] RFK Stadium Audio/Visual (MOTOTRBO digital)

Prince William 700 MHz Frequencies

Prince William County recently licensed several 700 MHz frequencies. All the frequencies are indicated for mobile use only (no repeaters). The radio service code is SG - Conventional Public Safety 700 MHz. It's assumed these frequencies will be used for interoperability with other DC-area jurisdictions that are installing 700 MHz equipment.

Major Gas Leak in Culpeper Yesterday

There was a major gas leak in Culpeper yesterday afternoon. Talkgroups 2256 (Culpeper Town Public Works), 42288 (Culpeper County Special Events 1 - used for police traffic control), and 43248 (Culpeper County Fire Ch. 12C) from the Fauquier/Culpeper/Rappahannock trunked system were active.

Loudoun County Project 25 Trunked System

Loudoun County's Project 25 trunked system is coming online. This system includes both Project 25 Phase I talkgroups (which can be monitored with current scanners) as well as TDMA talkgroups (which cannot be monitored with today's scanners). If any Phase I radio affiliates to a talkgroup, all transmissions on that talkgroup will be P25 Phase I. This means that scanner listeners still have some opportunity to monitor this system. See this RadioReference Forums thread for extensive discussion on the system.

Prince George's County P25 System Active

The Prince George's County Project 25 system has some activity on it. I'm seeing talkgroups 13 and 25 on site 101. Unfortunately, the traffic appears to be TDMA, which means it's not monitorable with a scanner.

Friday, December 4, 2009

PCM Construction FCC App

PCM Construction has an application pending before the FCC. The app calls for a UHF repeater and five simplex frequencies. The location of the repeater is Inova Fairfax Hospital, so this will probably be used for construction at the hospital.


Wednesday, December 2, 2009

Maret School FCC App

The Maret School, a private school located near the Washington National Cathedral, has an application pending before the FCC. The app calls for mobiles on 462.5125 and 467.5125, but it appears that the school will set up a repeater on 462.5125.

Saturday, November 28, 2009

Rappahannock Regional Jail Using MOTOTRBO

The Rappahannock Regional Jail in Stafford appears to be transitioning more operations to MOTOTRBO. They've been using TRBO on 453.8125, and today I also monitored TRBO on 453.9000.

Friday, November 27, 2009

Target Changing Frequency Plans

Target Stores appear to be changing frequency plans at some stores with "older" UHF frequencies. The Target in the Central Park shopping center in Fredericksburg has abandoned 461.0375, 466.2875, etc. The Target at Stafford Marketplace has abandoned 467.5125, 467.4875, etc. Both stores are now using the frequency plans of 467.7500, 467.7750, etc. This latter plan is the "newest" one Target has implemented in their stores. I assume they're pursuing nationwide consistency with their frequencies.

Potomac Mills Finds

Here are some frequency finds from Potomac Mills:

154.5700 [ 74.4] Gap

Crowne Plaza Silver Spring FCC App

The Crowne Plaza Silver Spring hotel has an application pending before the FCC. The app calls for a VHF repeater on 151.5350. The emission designator is coded 7K60FXE, so this will almost certainly be MOTOTRBO.

Saturday, November 21, 2009

Orange County Schools Using MOTOTRBO

Orange County, VA is probably outside the range of a good part of Metro DC, but those in the Northern Virginia/Fredericksburg area may be able to monitor it. The school buses are now using MOTOTRBO on 154.0550. Previously, they were on 155.5650 [179.9], but this appears to be silent now. The schools are licensed under WXT819.

Children's National Medical Center FCC App

Children's National Medical Center has an application pending before the FCC. The app calls for a base station on 462.4250, as well as two mobile units on the same frequency. The app also calls for 400 paging units on this frequency. Based on the number of paging units, it appears that this frequency will be primarily used for paging, as opposed to two-way radio.

Saturday, November 14, 2009

Fredericksburg Weather Radio Operational

The Fredericksburg NOAA weather radio station is active. It's on 162.4250 and broadcasts from Mary Washington Hospital. The station rebroadcasts the Manassas station, which is on 162.5500 (KHB36).

More Marathon Ideas

Here are a few more frequencies to try out during the Marine Corps Marathon tomorrow:
  • 123.0250 (AM) was active last year with helicopters. This is a common helo air-to-air frequency which is used nationwide.
  • 145.1900 [151.4] and 449.9750 [107.2] were active last year with amateur radio operators. It's unknown if the same frequencies will be active this year, but there's probably a good chance of it.
  • 154.6650 [ CSQ] was used last year by Virginia State Police doing traffic control on the 14th Street Bridge, I-395, exit ramps, etc.

Marine Corps Marathon

The Marine Corps Marathon is this Sunday morning. The marathon is one of Washington's biggest events of the year, and provides a wealth of scanning opportunities. Here's a preliminary list of what I'll be monitoring, in rough order of importance (I'll try to go into more detail in the coming days):
  • Marine Corps P25 Trunked System - look for talkgroups in the 63xxx range. In previous years, this system has seen widely varying levels of encryption.
  • Arlington County P25 Trunked System - numerous talkgroups will be active, especially on the police side.
  • DC Trunked System - look for the SOD channel and/or Citywide 2 to be active with traffic control. The three DCFD Special Events channels should see heavy use.
  • Metro Trunked System - expect Transit Police to be very busy with crowd control, especially at key stations like Arlington Cemetery, Rosslyn, and Pentagon. The Police Tac channels have been active in previous years.
  • Park Police - expect to see 166.7250 [127.3] (R) in use.
  • Crystal City Security - Crystal City hosts a big street festival during the marathon. Security active on 451.7750 [ d205] (R).
Notes from past years are on my Arlington County page.

STARS Coming Online in Northern Virginia

STARS, Virginia's statewide radio system, is slowly appearing in Northern Virginia. Yesterday, two new sites were online. Site 117, which appears to be transmitting from Fairfax, was using 152.2025 for a control channel. Site 119, which appears to be transmitting from Arlington, was using 152.5325 for a control channel. No voice traffic was heard on either in the late afternoon. Expect radio testing to continue for several weeks, at a minimum.

Washington International Horse Show

The Washington International Horse Show began yesterday and runs through Sunday. I had a chance to do some frequency-hunting yesterday; unfortunately, last night seemed somewhat slow, since it was the first day. Expect most of the best traffic on Friday and Saturday nights.

464.6250 [127.3] Inside Operations? (Channel 1) (R)
464.7250 [192.8] Outside Operations? (Channel 3?) (R)

Spotsylvania Regional Medical Center FCC App

The Spotsylvania Regional Medical Center, which is scheduled to open in June 2010, has an application pending before the FCC. The app calls for two UHF repeaters (452.4375 and 463.5625). The frequencies are coded with emission designators for both analog and MOTOTRBO.

Thursday, October 15, 2009

Capitol Radio Communications FCC App

Capitol Radio Communications, which provides commercial radio services, has an application pending before the FCC. The app calls for two repeaters and eight simplex frequencies. The repeaters are supposed to operate at 22000 America Online Way. This is the headquarters of America Online, and America Online has used the two repeaters (463.4500 and 464.9750) for some time now. It's possible that Capitol Radio Communications is taking over the maintenance of the frequencies.

Update on Spotsylvania Rebanding

Spotsylvania has added another frequency to their rebanded trunked system. It's 852.6750 and it's in position 8 of the channel order (LCN). Note that for whatever reason, sometimes all the frequencies aren't used. For example, yesterday 851.6125 was not being used. It's a good idea, however, to keep all the frequencies programmed, as one never knows when they will turn a frequency on or off.

Monday, October 12, 2009

Spotsylvania County Rebanded

Spotsylvania County has rebanded their EDACS trunked system. Here is the updated logical channel numbering (LCN):

856.4875 (1)
857.4875 (2)
858.4875 (3)
859.4875 (4)
851.6125 (6)
852.4000 (7)
852.1750 (9)
852.6250 (10)
853.1000 (11)

Note that positions 5 and 8 are unoccupied.

The site ID has also been changed from 1 to 10. The site ID for the Lake Wilderness tower (2) has not changed.

Virginia State Fair Wrap-Up

Here's what I monitored at the Virginia State Fair, which concluded this weekend:

Virginia State Police used talkgroup 96 (Richmond 3) on STARS for traffic control/parking. VSP and medical teams primarily used talkgroup 6162 for internal operations. Talkgroup 6163 was also used, and was identified as "Channel 2." These talkgroups originated from the "STARS trailer" mobile system on-site. The control channel for this low-power system was 868.9250.

155.2200 [ d546] Caroline Fire/Rescue?
451.3375 [ d411] Parking
451.4375 [ d411] Engineering/Electrical

700 MHz Trunked Systems

With the Prince George's 700 MHz Project 25 trunked system beginning to see some use, I thought a summary of the state of 700 MHz in the region might be in order:
  • Prince George's County: system being used at least for events at FedEx Field (one Redskins game and U2 concert).
  • Stafford County: system licensed (WQKD203 and WQKD204), but no control channel on-air. Appears to be a twelve-site simulcast system.
  • Metropolitan Washington Airports Authority: system licensed (WQKR977), but no control channel believed to be active. Appears to be a three-site Smartzone system. See previous post.
  • Loudoun County: According to post on RadioReference, Loudoun may be getting 700 MHz system. The county has no license for it, however.

U2 Concert Finds

Here are some finds from the U2 concert last night at FedEx Field:

461.1375 [ d152] CSC Event Staff (Supervisors?)
461.2375 [ d152] CSC Event Staff (Security around band/Backstage)
461.3875 [ d152] CSC Event Staff (Inside Stadium)
461.4375 [ d152] CSC Event Staff (Gates, Line Control)

461.2375 [ d311] U2 Production Staff
461.3375 [ d413] U2 Production Staff
466.0375 [ d532] U2 Production Staff
466.1375 [ d734] U2 Production Staff

461.0625 [ d343] Blackberry Promotional Display Staff
464.6000 [ 88.5] Private Medics?? (personnel on field)

Many FedEx Field frequencies were active (see Prince George's County page).

Police used 494.7375 [127.3] (inside) and 494.8875 [127.3] (outside/traffic).

Fire/EMS used talkgroup 2001 from the Prince George's County P25 trunked system. This talkgroup was seen on both site 101 and site 102 of the system. The "base" radio ID was i2528050.

MWAA Licenses 700 MHz Frequencies

Joining the increasing number of jurisdictions around the region moving to the 700 MHz band, the Metropolitan Washington Airports Authority (MWAA) recently licensed frequencies in said band. These frequencies will probably be used for a Project 25 digital trunked system to replace the current Project 16 trunked system.

Based on the license, the new system will probably be configured as Smartzone, as opposed to the current system's simulcast configuration. This means that the mobile or portable radio will automatically select the strongest site (Dulles, Reagan National, Dulles Toll Road) based on where the radio user is located. One practical implication for scanner listeners: the majority of transmissions on a particular site will be from units that "belong" to that site. For example, most transmissions on the Dulles site will be from Dulles units. With the current system, a scanner listener simply needs to program one set of frequencies, and is able to hear transmissions from all units, whether they're at Dulles, Reagan National, or in-between.

The license indicates the system will support 1500 mobile units.

Here are the sites, and the frequencies to be used at each one:


Reagan National

Dulles Toll Road

J&J Worldwide Services FCC App

J&J Worldwide Services, which provides facilities management services at Fort Belvoir, has an application pending before the FCC. The app calls for a UHF repeater on 463.5875.

National Book Festival Finds

Here's what I found at Saturday's National Book Festival:

151.5125 [173.8] Pavilion Managers/Ushers (Channel 2?)
152.9150 [123.0] Base Command (Channel 1?)
155.9100 [146.2] Transportation Command/Golf Carts (Channel 3)
157.8150 [141.3] Electrical
158.0100 [156.7] Volunteers?/Line Captains
Radio rentals from USA Radio Rentals.

410.3375 [ d411] "LSOs"; OSEF units; Security
467.8750 [ d432] Borders Books (Book Sales Tent)
469.5000 [ d125] Audio/Visual

The VHF channels have been used in previous years at the Race for the Cure. The parent company of USA Radio Rentals is Blanchard Communications. I've never found a license for these frequencies.

The 410.3375 may be a Library of Congress frequency, since the LOC produces the Book Festival. This frequency was also active at the 2005 Festival.

Friday, September 25, 2009

Virginia State Fair

The Virginia State Fair began yesterday and runs through October 4. The Fair is now located in Caroline County, near Kings Dominion (previously, it was in Richmond). Virginia State Police are using STARS talkgroup 96 (which they call "Richmond 3") for communications. This talkgroup can be heard on the Thornburg tower.

Although I haven't monitored them personally, fair organizers will probably be using these eight simplex frequencies, which were licensed earlier this year:


Weekend Events

Here are a couple of major events this weekend:

The National Book Festival is tomorrow on the National Mall. The one time I attended in 2005, I was surprised at the number of frequencies in use. Here's the list:

464.5000 [ d131]
464.6000 [ d134]
464.6250 [ d516]

STARS Site 108 Update

There's been some question on RadioReference as to whether STARS site 108 is really located at Independent Hill. One person speculated that it may be located at Hogback Mountain. There is a Hogback Mountain southwest of Leesburg, and another in Rappahannock County.

Site 108 wasn't on the air this morning. It seems to be "turned-on" only during the day on weekdays so far.

Oce Business Services FCC App

Oce Business Services, which engages in document process management, has an application pending before the FCC. The app calls for five UHF simplex frequencies.

Maryland State Fair

The Maryland State Fair runs today through September 7 (Labor Day). I don't have notes from a previous year, but I do remember the radio usage by the fair organizers was fairly minimal for an event this big. I think they were using a VHF business channel in simplex mode. The Baltimore County Public Safety trunked system and the Baltimore County Services trunked system will probably have some active talkgroups.

Sen. Kennedy's body is scheduled to arrive tomorrow at 3 PM at Andrews AFB. The base P25 trunked system should be active. At 4:30, the motorcade will arrive at the Capitol. Here are the Capitol Police frequencies:

Arlington County is using a new encrypted talkgroup on their P25 trunked system. It's talkgroup 193, which is one above talkgroup 192, "Arlington Public Health 2."

Montgomery Trunked System Works in Metro

Not sure if this has been mentioned before, but the Montgomery County trunked system works underground in the Metro (at least at the Bethesda station). This means that DC, Arlington County, and Montgomery all have underground Metro coverage.

Sunday, August 23, 2009

Arlington and Montgomery County Fairs

The Arlington County Fair (closes today) is using talkgroup 11 for Police and talkgroup 105 for Parks & Recreation organizers from the Arlington P25 trunked system. Talkgroup 105 has never been seen in use before.

Many of the FedEx Field frequencies were also in use. 453.6125 [151.4] was used by Prince George's Fire/EMS; this may have replaced 500.1000 [127.3], which was not heard.

Women of Faith Frequencies Found

Here are frequencies found from the Women of Faith conference this past weekend. These frequencies won't be useful in Washington until next year, but the conference will be traveling around the country for the next few months, and I expect these same frequencies to be used.

Legg Mason Tennis Classic Frequencies Found

Here are some frequencies in use at the Legg Mason Tennis Classic, which continues through this Sunday. They apparently are not renting the radios from Valleywide Communications this year, as the frequencies are different from what they've used in the past. The rental company may be Blanchard's/USA Radio Rentals. I may get another chance to monitor the event, so look for an update.

166.8500 [127.3] Park Police (Channel 4) (S)
461.2250 [ d624] Parking

FCC License for Valleywide Communications

I've found an FCC license for Valleywide Communications, the entity that may be providing rental radios for the Legg Mason Tennis Classic. The license lists sixteen UHF simplex frequencies, and many of them (though not all) have been used in previous years at the Legg Mason.

Weekend Events

Three major events this weekend:

The Women of Faith Conference is at Verizon Center today and tomorrow. The organization recently licensed fifteen UHF simplex frequencies for nationwide use.

Paul McCartney will be in concert at FedEx Field tomorrow night. The stadium has a ton of frequencies, many of which will probably be in use for the concert. They're listed on the Prince George's County page.

The Legg Mason Tennis Classic begins tomorrow and continues through next Sunday at the Fitzgerald Tennis Center in Rock Creek Park. The tournament has rented UHF radios from Valleywide Communications in the past. Here are frequencies found from the 2007 tournament (no info from last year):

The transmitter is in Silver Spring. FleetTalk owns the LTR trunked system in Silver Spring that was formerly owned by Champion Communications.

JetBlue Airways (BWI) FCC App

Friday, July 10, 2009

Weekend Event

After several events last weekend, this weekend seems a bit quieter. The only major event I can find is the first-ever concert at Nationals Park, with Billy Joel and Elton John. Most of the frequencies normally used at Nats Park will probably be in use for the concert:
  • MPD will probably use either talkgroup 16656 or 21232.
  • DCFD will probably use either 2096, 2112, or 2128. They may patch the talkgroup to 867.4875 [156.7].
  • Nationals Park staff will be using their MOTOTRBO frequencies (unmonitorable).
  • CSC Event Staff, which provides crowd control/security at baseball games, could very well be working this concert. Look for them on 463.8000 [ d152] (R), 461.3875 [ d152] (S), and 461.1375 [ d152] (S).
  • The people working the actual concert could use a wide variety of frequencies, probably simplex. I would look first between 461-470 MHz. Also check 451-453 and the VHF itinerants.

Thursday, July 9, 2009

W Hotel FCC App

The W Washington Hotel, which opened yesterday, has an application pending before the FCC. The app calls for a UHF repeater on 463.9875.

Many other W hotels around the country use MOTOTRBO radios, so it's interesting that this one is apparently using analog radios. Of course, they may use the TRBO radios, and not have indicated that on the license.

AT&T National at Congressional Country Club

The AT&T National golf tournament at Congressional Country Club began yesterday and continues through Sunday. Here are eight confirmed frequencies for the Club:

152.4050 [ d115] Security
151.8650 [ d115] Grounds (R)

Gallaudet University FCC App

Gallaudet University has an application pending before the FCC. The app calls for a UHF simplex frequency of 467.8000. The frequency is to be used for the "university counseling center for the hearing impaired."

King George Schools Switch to MOTOTRBO

King George Schools has switched to MOTOTRBO on their school bus frequency of 151.7750. They were discussing the switch to TRBO on their old analog channel of 151.7750 [ d114]. They seemed to be doing lots of talking using the TRBO mode; I assume this was for radio testing of all the buses.

Windsor at Potomac Vista FCC App

Windsor at Potomac Vista, an apartment complex in Woodbridge, has an application pending before the FCC. The app calls for five UHF simplex frequencies.

Smithsonian Folklife Festival Freqs Found

Here's what I found yesterday at the Smithsonian Folklife Festival. This year, the organizers are using MOTOTRBO radios (in analog mode). The radios didn't have any kind of sticker on them which would indicate the rental company. It's also unknown how many channels they are using.

451.8000 [ d026] Tech
456.8125 [ d306] Park Police
461.0875 [ d606] Program Channel
461.1625 [ d116] Audio/Visual?
461.2375 [ d445] Security
461.3125 [ d054] Ice/Beverage
466.0375 [ d155] Talk (Ch. 10)
There is a "Stage Audio" channel.

Barbecue Battle Freqs/Talkgroups Found

Here's what I found yesterday at the Barbecue Battle. The event concludes today.

461.1250 [ d365] Production
461.5250 [ d546] Audio/Visual
463.7250 [ d306] Gates
464.2750 [ d445] Beverage
464.9250 [ d632] Safeway Tent
MPD used talkgroup 21232 (Citywide 2). DCFD used talkgroup 2128 (Special Events 3). Department of Health used talkgroup 34448.

The radios used by the organizers looked to have about ten channels printed on them. No radio rental provider was seen.

Weekend Events

There are two major events this weekend in DC: the Smithsonian Folklife Festival, and the National Capital Barbecue Battle. Both events run Saturday and Sunday. The Folklife Festival is on the Mall, and the Barbecue Battle is on Pennsylvania Avenue between 9th and 14th Streets.

In previous years, the Folklife Festival has used a variety of rented UHF repeaters and simplex frequencies. In 2004, they even used talkgroups on the Smithsonian's LTR Passport system. Here are the frequencies used last year:

461.0750 [ d152] "Program" Channel (R)
461.1250 [ d172] Audio/Visual? (R)
461.2500 [192.8] Brief transmission monitored about weather update
464.9250 [141.3] Administration? (R)

Last weekend, I may have heard the Folklife Festival people setting up. If it was them, they were using some common UHF itinerant frequencies, such as 451.8000, 451.8125, 456.8000, 456.8125, etc.

The Barbecue Battle has also used a variety of rented UHF frequencies over the years. Here's what I found last year:

457.5125 [ d412]
459.4125 [ d743] Logistics?
460.6125 [ d223] Safeway Tent
461.21875 [ d371] Production (Channel 3)
462.3250 [141.3] Security/Medical
462.7125 [ 77.0] Stage Operations?
464.1625 [ d464]
465.8375 [167.9] Gate/Beverage Managers (Channel 2)
467.0125 [225.7]
468.0125 [ d664] Area Managers (Channel 10)

DC Trunked System Talkgroups:
2112 DC Fire Special Events 2
21232 MPD Citywide 2
34448 Department of Health
35536 Emergency Management Agency
35600 Traffic Management Center

In previous years, the event has used the common rental frequencies used by Bearcom Rentals and others (464.5/464.55/464.6/464.625/464.65/464.7/464.725/464.75 and their +5 MHz counterparts).

Special Operations Group FCC App

Special Operations Group, which provides private security in the DC area, has an application pending before the FCC. The app calls for three UHF simplex frequencies.

Nationals Park Update

I attended the Tuesday game against the Red Sox, and had a chance to do some monitoring. Here are some new finds:

461.1375 [d152] CSC Event Staff (S) (only a brief transmission heard; rarely-used frequency; may be for something special like VIP security since Red Sox were in town)
462.5500 [CSQ] mentioned an "order" and "didn't get beer"
467.9250 [67.0] Vendors

867.4875 [156.7] seems to be consistently patched to talkgroup 2096 on the DC trunked system. Previously, DCFD was using the simplex frequency for ops inside the stadium, and the talkgroup for outside operations. Now, inside and outside personnel are on the same frequency/talkgroup.

Metrorail Green Line personnel were using talkgroup 32944 for operations at the Navy Yard Station last night. Previously, Green Line Supervisors used talkgroup 33136. Transit Police were using Tac 8 (talkgroup 50256) last night; they've used Tac 6 and 7 before.

And a couple of frequencies monitored, but not related to Nats Park: 464.2500 [d654] is security for an unknown hospital; they mentioned an "upper helipad." That must mean they have at least one more helipad, which would probably imply a sizeable hospital. They've also mentioned a "pavilion" on this frequency before. And 461.2125 [d754] sounds like a hotel near Nats Park, possibly the Courtyard by Marriott. They mentioned an "eighth floor," which the Courtyard has.

Metro Train Collision

I got a chance to do some monitoring of the Metro trunked system and the DC trunked system (800 MHz) in the hours after Monday's tragic train collision. Neither of these systems comes in well in Fredericksburg, but the warm weather and nighttime hours probably helped reception somewhat. The scanner had trouble decoding the digital on 490.8875 (Metro trunked system) for some reason, so I was never able to hear a transmission on this frequency.

Metro Trunked System talkgroups:
1744 Buses
1840 returning shuttles to Virginia; "SOMs" (sometimes patched to 1904)
1904 Shuttles (sometimes patched to 1840)
1968 talking about keying up VHF radios
24688 Bus Supervisors
32784 Red Line Ops
32976 no voice; Red Line Supervisors?
50224 Metro Transit PD Tac 7

DC Trunked System talkgroups:
1648 DCFD 03 (primary operations)
1680 DCFD 05 (rescue/shoring/recovery)
1936 DCFD 013 ELO (EMS Liaison Officer) (EMS coordination/hospital status)
2720 DCFD 014 Stage-0 (coordinating Montgomery County fillers)
2752 Encrypted
9840 "rehab"
33840 Emergency Management Agency
33872 Emergency Management Agency
34448 Department of Health

400 Fire/EMS (Channel 2G)

DC Trunked System talkgroups:
2080 DCFD Inspectors (fireworks safety)
18320 MPD Harbor Patrol (fireworks safety)

Friday, June 19, 2009

Alexandria Red Cross Waterfront Festival

The Alexandria Red Cross Waterfront Festival is this weekend. Here are frequencies and talkgroups used last year:

458.4250 [ d754]
463.2500 [ d315]
464.6250 [ d431] Beer?
464.7500 [ d631] Logistics?
469.6000 [ d023] Gates/General Ops?
469.7000 [ d212] Security

Alexandria Trunked System Talkgroups:
48 Alexandria Police (Channel 3)
400 Alexandria Fire/EMS (Channel 2G)
1072 Citywide 1 (shuttle buses/other miscellaneous users)

In 2006, for fireworks safety/coordination, talkgroup 1696 on the Airports Authority trunked system and talkgroup 2080 on the DC trunked system were used.

Lake Anna State Park

Spent the afternoon yesterday at Lake Anna State Park in Spotsylvania. The park continues to use 151.4000 [CSQ] for operations and law enforcement. A Department of Conservation and Recreation (DCR) law enforcement officer who was patrolling on foot appeared to have a 700/800 STARS portable, but I never saw him use it. Most of the DCR vehicles I saw had older VHF radios installed, probably only capable of the legacy 151.2350 and 151.4000 channels.

As for STARS sites, I had a difficult time picking up any of them from the park. The Fork Mountain site seemed to be the strongest, sometimes reaching five bars on the signal strength meter, but moving the scanner even slightly caused the signal to drop significantly. The Louisa site was able to be monitored, but it was not as strong as Fork Mountain. The only DCR talkgroups monitored were 2005 and 2013, but there was very little traffic on either. Department of Game and Inland Fisheries talkgroup 3236 (Law 5) was somewhat active throughout the afternoon.

The Coast Guard Auxiliary (unit 868) was using Marine Channel 21A (157.0500) to communicate with "Lake Anna Station." Lake Anna Station must have been at another location on Lake Anna, as they were somewhat weak from the state park.

Louisa Sheriff (155.5500) and Louisa Fire (155.8050) were very strong at the park.

The Spotsylvania trunked system was able to be monitored, but usually had a lot of static (much weaker than the Louisa channels).

The North Anna Power Station trunked system came in fairly well. The only talkgroup active, as expected, was security on 9648.

Georgetown University FCC App

Georgetown University has an application pending before the FCC. The app calls for a UHF repeater on 452.3625, with 500 5-watt mobile units. The Office of University Safety is apparently coordinating this app.

Tuesday, June 9, 2009

Mount Vernon FCC App

Mount Vernon has an application pending before the FCC. The app calls for a UHF repeater on 452.3875 to be used for "maintenance and security activities." (Mount Vernon currently uses 464.5250 [ d073] for security, and 464.4750 [ d116] for maintenance.)

Friday, June 5, 2009

Weekend Events

Here are two events this weekend:

The Komen Global Race for the Cure is Saturday on the National Mall. This event usually attracts 50,000+ runners and walkers. In 2006 and 2007 (no data for 2008), organizers used VHF rental radios. Park Police will probably use 166.7250 [127.3]. MPD will probably use either talkgroup 16656 or 21232. DCFD will probably use one of the Special Event talkgroups (2096, 2112, 2128).

Celebrate Fairfax runs Friday night, Saturday, and Sunday. Organizers may use the analog coordination talkgroups on the Fairfax County Services trunked system. (The coordination talkgroups have been in use for other recent events in Fairfax County.) In previous years, organizers used UHF rental radios. County police/fire will probably use a few talkgroups on the Fairfax County Public Safety trunked system. (Last year, police used digital Coordination 2 and fire used digital Coordination 3.)

Monday, June 1, 2009

Market Common Clarendon

Spent some time in Clarendon on Saturday, and picked up a few more frequencies for Market Common. Here's the latest list:

151.7600 [ 67.0] Pottery Barn
154.6000 [ 67.0] Williams-Sonoma
461.2625 [ 74.4] Apple
464.5000 [186.2] The Container Store
466.0375 [ 94.8] Ann Taylor Loft

151.6250 [ 91.5] Pace cars/motorcycles
459.9375 [141.3] Specific cycling team?
469.7500 [ d371] Organizers
Arlington Police used talkgroup 11 (1K - Special Operations Section).

Washington Folk Festival

Here are frequencies used at the Washington Folk Festival this past weekend at Glen Echo Park:

169.7750 [NAC 4C5] National Park Service (S)
467.7500 [100.0] Organizers
469.5500 [ d506] Organizers

169.7750, when used as a repeater, is the frequency for the George Washington Memorial Parkway. The Park Service was using it in simplex mode at Glen Echo Park. (Glen Echo is administed by the Park Service as part of the GW Parkway.)

Herndon Festival

The Herndon Festival was this past weekend, and organizers used talkgroups 24272, 24304, and 24336 (Coordination A1, A2, and A3) from the Fairfax County Services trunked system. With more and more festivals in Fairfax County using these talkgroups, this may indicate that Celebrate Fairfax (June 5-7) may use them as well.

Arlington P25 Trunked System in Metro Tunnels

Arlington County has apparently installed the equipment to allow their Project 25 trunked system to broadcast in the Metrorail tunnels. It is up and running in at least the Clarendon, Court House, and Rosslyn stations and the tunnels in between. Previously, they had a single 800 MHz conventional repeater for fire (856.4875) and police (858.4875). These frequencies appear to still be in place.

Thursday, May 28, 2009

Potomac Hospital FCC App

Potomac Hospital has an application pending before the FCC. The app calls for two UHF repeaters (461.8500 and 462.2750) to be used for security and maintenance.

CSC Event Staff--New Repeater at Nats Park

CSC Event Staff, the organization that provides security/crowd control for the Washington Nationals on game days, has a new repeater at Nationals Park. They are using 463.8000 [ d152]. This appears to replace 461.5125 [ d152], which they were using before for the "Command Post." They are still using 461.3875 [ d152] in simplex mode for on-field personnel.

I happened to find this repeater accidentally at Saturday's game against the Orioles. They appear to have just licensed it earlier this month.

Scanner Master Review of BCD396XT Scanner

Scanner Master has an in-depth review of the BCD396XT scanner on its website. It's quite detailed for a commercial (as opposed to hobbyist) website, and includes criticisms as well as praises. It also does a good job comparing the scanner to the PSR-500/Pro-106, which is helpful for people trying to decide between them.

Tuesday, May 26, 2009

United Medical Center Switched to MOTOTRBO?

United Medical Center (formerly Greater Southeast Community Hospital) may have recently switched to MOTOTRBO. Their previous frequency of 464.8250 [186.2] was silent on Saturday, but a MOTOTRBO user of comparable strength and range was noted on 464.8250. (Georgetown Hospital continues to use the frequency with a tone of [192.8].)

Thursday, May 21, 2009

NSWC Indian Head Trunked System Coming Alive

The 380 MHz trunked system at NSWC Indian Head is beginning to have some activity. Talkgroup 22613 is used by security/police. This may have replaced 140.5250. No other talkgroups have been monitored. The current control channel is 381.7000.

Sirius XM Satellite Radio FCC App

Sirius XM Satellite Radio has an application pending before the FCC.  The app calls for two UHF repeaters.  These frequencies will be used for "internal security operations" at their headquarters in Northeast Washington.


Tuesday, May 19, 2009

Weekend Events

There are quite a few events this weekend:
  • The DC101 Chili Cook-Off is Saturday at RFK Stadium.  464.3750 [110.9] is used for general RFK operations.  461.8125 [ d311] is used for RFK Guest Services.  Try 461.5125 [ d152] for CSC Event Staff (security/crowd control).  Last year, the organizers used 461.4250 [103.5], but their frequency is not very consistent year-to-year.  DC Fire will probably be using one of the Special Events talkgroups (2096, 2112, 2128).  MPD may use talkgroup 21232 or 16656.
  • The Joint Services Open House is Saturday and Sunday at Andrews AFB.  See the "Special Events" section of this page for a good run-down of what was used last year at the air show.
  • The Preakness is Saturday at Pimlico in Baltimore.  451.9875 [ d223] and 461.5375 [179.9] were previously used at Pimlico, but appear to have been deleted from the current license.  Baltimore Police and Fire have many "special events" talkgroups available to them on their trunked system; they'll probably be on one/several of those.

Prince George's County Project 25 System Online

Prince George's County has their new Project 25 (Phase II?) system on the air.  I'm getting a control channel of 774.68125 this morning in Fredericksburg.  The system ID is 2A8 and the WACN is BEE00.  No talkgroups seen.  This information has been added to RadioReference.

By the way, the tropospheric ducting has been good this morning, which is why I was able to receive this system.

A Few Business Finds in DC

Harman Hall, one of two venues for the Shakespeare Theater Company, is using 452.6625 [ d503] and 457.7125 [ d503].  Both of these are simplex.

The new Courtyard Washington/U.S. Capitol, which opened earlier this month, is using 461.4875 [210.7] for security, engineering, and housekeeping.  It appears to be a simplex frequency.

The Red Roof Inn, near the Verizon Center, is using VHF portables.  The frequency has not been confirmed, but 154.6000 [  67.0] was heard in the area in the past.

Weekend Events

Here are a couple of weekend events with some scanning opportunities:
  1. World Bank/IMF Spring Meetings: World Bank security uses 151.9550 [107.2] in a base/mobile configuration.  The base side can be heard from many locations in the DC area.  World Bank engineering uses a repeater on 463.7500 [ d606].  There is no radio information for the IMF.
  2. Capitals Playoff Game: Best thing to listen to at the Verizon Center is probably CSC Event Staff on 461.5125 [ d152].  (They've also been heard on 464.5000 [ d152] at Verizon.)  Also check out Gallery Place security on 461.3250 [ d411].

Stafford County Trunked System FCC License

Stafford County was recently issued two licenses (WQKD203, WQKD204) for a 700 MHz public safety trunked system.

According to the licenses, the system will have ten frequencies, twelve sites, 1200 mobile units, and forty-two "base stations."

The frequencies have an emission designator of 8K60D7W, which probably indicates a Project 25 Phase II system.  (This is the same emission designator as the new Prince George's County system--which is supposed to be P25 Phase II.)

A quick search of the 700 MHz band did not turn up a control channel, so the system probably isn't active yet.

Chevy Chase Golf Club FCC License

Chevy Chase Golf Club was recently issued an FCC license.  The license shows a UHF repeater on 464.8375.  The frequency is to be used by maintenance personnel.

Fredericksburg Auto Auction FCC App

Fredericksburg Auto Auction has an application pending before the FCC.  The app calls for two UHF repeaters and four simplex frequencies.  Note that this business has already been using the two repeater frequencies for several years; I believe they were on a previous (now-expired) license.

Boston Properties (Springfield) New License

Boston Properties, a property-management company, was recently issued an FCC license for a repeater on 461.8750.  This will be used at a building at 7375 Boston Blvd. in Springfield.

National Marathon Saturday

The National Marathon is tomorrow.  This event begins and ends at RFK Stadium.  In previous years, most of the good listening was found on the DC trunked system and amateur radio.  Surprisingly, the race organizers have not used two-way radio since the marathon began in 2006.  Here are some notes from last year:

Major Changes to the Fairfax County Page

I've redesigned the Fairfax County page on my website.  Most notably, I've organized and consolidated the business listings.  I've put all the businesses into categories, such as "Hotels," "Retail," "Property Management," "Attractions," etc.  This shortens the length of the page considerably, and makes it easier to find similar frequencies.  No longer is there simply one long alphabetical list of every business.

I plan to slowly do this with more pages, but each one takes a considerable amount of time, so it may be a while before all pages are redesigned.

Volo Aviation FCC App

JNCR Dahlgren Site Activity Increasing

Recently, there has been an increase in activity on the JNCR Dahlgren trunked system.  Most of the traffic has been on talkgroup 22311.  The system is obviously still in the testing stages--the primary base radio traffic remains on the LTR system.  The switch to the new system may occur when public safety agencies on the base move into a new communications center.

Great Falls Park Monitoring

While at Great Falls Park on Sunday, I picked up a few frequency confirmations:
  • 170.0500 [NAC 4C5] Great Falls Park
  • 169.6875 [NAC 4C5] C&O Canal National Historical Park (This frequency was strong at Great Falls.  A reference to the "Monocacy Aqueduct" was monitored.  170.3625 [NAC 4C5] was active at same time, but much weaker.)
  • 461.1625 [110.9] Madeira School (R)

Park Service/Battlefields Update

The family and I took a trip up to the Manassas Battlefield Sunday afternoon before the Super Bowl.  Here are some updates to National Park Service frequencies:

172.7250 [NAC 47C] Manassas NBP
170.0500 [NAC 5C2] Monocacy NB (this frequency may be shared with Antietam NB)
170.3625 [NAC 4C5] this frequency was weak from Manassas, but has the characteristic Park Service NAC.  I couldn't make out who it was, but suspect it may be C&O Canal NHP.  A user on RadioReference has also reported hearing 169.6875 [NAC 4C5]; this may be another C&O repeater.

National Park Service--Filling in the Blanks

Anyone have information on some of these National Park Service parks in the Northern Virginia/DC area?
  • Manassas National Battlefield Park: I have 163.120 [NAC 375], but suspect this may be incorrect.  The George Washington Birthplace National Monument uses this same frequency and NAC, so that's why I'm suspicious of it being used at Manassas.  I think I remember seeing an old listing for Manassas in the 170.xxxx range.
  • C&O Canal National Historical Park: This park has supposedly switched from analog frequencies to digital ones.  It's unknown if their old ones are still in use (166.9500/168.3000).
  • National Capital Parks - East: This group of parks was monitored briefly on 168.4250 [NAC 293].  This was the frequency they used before switching to digital.  They may change frequencies in the future.  Note that there is also another analog user on this frequency, who can be heard from the DC area and from Fredericksburg.  The user sounds like a security operation, and transmits CSQ.
  • Fredericksburg & Spotsylvania National Military Park: This park continues to use 166.9500 [127.3].  Unknown if they'll be switching to digital.
  • Shenandoah National Park: I can hear five simulcast repeaters from my location in Fredericksburg.  The Park's digital radio system has been installed for several years.  The inputs to the various repeaters are not known.  Encryption is in use somewhat frequently, mostly by law enforcement units.
