Alexandria P25 Trunked System Growing

Alexandria's Project 25 trunked system, which will eventually replace the legacy Project 16 system, is being brought online. Several police talkgroups were active today; these are still being simulcast on the old system. Fire talkgroups do not appear to be in regular use, but there was some testing on them. Several city services talkgroups are also active on the new system.

Alexandria, like Fairfax, appears to be using the same hexadecimal talkgroup numbers on the P25 system that were used on the P16 system. For example, Alexandria Police Channel 1 is hex 1 (decimal 16) on the P16 system. It is also hex 1 on the P25 system (which works out to decimal 1).
