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.

Prince George's County New 700 MHz Licenses

Prince George's County was recently licensed for many 700 MHz frequencies.  The county will be building a Project 25 Phase II radio system--one of the first in the country.


Prince George's was also licensed for some 800 MHz frequencies, which are to be used in Metrorail tunnels.

Prince William Forest Park New Freq/NAC

I found the new frequency and NAC for the Prince William Forest Park today.  They're using 172.5000 with a NAC of 754.  I don't know the repeater input.  Base appears to identify as "Central."

Inauguration Logs Coming

I have a TON of logs from the Inauguration.  I'll try to clean them up and post them to the website in the next few days.  Stand by...

Raw Data from Today

I have put some very raw data that I collected today from Gravelly Point.  There are many abbreviations, etc.  Some of the frequencies are not even related to the Inaugural events, but most are.  In short, use caution with this data until I get a chance to process it.

Go to this address: Events.  The raw data starts several lines down, and is clearly delineated.

Other Pre-Inauguration Finds

Here are a few more pre-Inauguration finds:
  • 866.0125 [156.7] (used as an interoperability channel among numerous agencies)
  • DC TRS 37648 (unknown use, probably related to Inauguration)
  • Arlington TRS 136 (Coordination 2)
  • Fairfax TRS 20640 (encrypted, unknown use, probably an NCR channel)

CBP Active in DC

The Customs and Border Protection helos are active over DC.  They're on the nationwide CBP frequency of 165.2375 [100.0].

From my location in Fredericksburg, I heard a few calls from the helos on the input frequency of 166.4375 [100.0] this afternoon.  (The repeater out freq is very weak.)

Quantico Fire Using Prince William Numbering?

It appears that fire apparatus from Quantico Marine Corps Base are now using Prince William's numbering scheme.  I have heard Engine 533 on Quantico's FD freq (149.3500).

FLASH: LTR System In Use for Inaugural Set-up

The people setting up the various stages/platforms and the audio/visual systems for the Inauguration are using an LTR system on the National Mall.  Here are the details:

452.0375 (1), 452.2875 (2), 452.4875 (3), 452.6875 (4), 452.8875 (5)
0-01-010"looking for shuttle"
0-01-015talking about scheduling workers, etc.
0-01-019Cranes? "Staging 1"?

There are several other talkgroups in use, but I could not identify their uses.  Talkgroups referenced included "Staging 1," "Staging 2," and "Catering."

Note that this system is fairly low-powered, so one needs to be fairly close to receive it.  (I was monitoring yesterday from Gravelly Point, and was able to receive fairly well.)  452.0375 appears to have better signal strength than the other four repeaters.

This system may also be used during events on Inauguration Day.

Popular Communications Article about Inauguration

The January 2009 issue of the magazine Popular Communications has an article about the Inauguration.  It's written by Alan Henney, a DC scanning expert and veteran of previous Inaugurations.  I haven't read the article, but I'll be checking it out the next time I'm in Borders.
