Hi,

I have come across the following Talkgroups for Fairfax County:

17523
17043
17331
16947

17043, 17331 & 16947 come up quite frequently and sound like Police talkgroups but I am not sure for which area.

I don't see them listed at http://www.radioreference.com/modules.php?name=TRSDB&sid=182 Does anyone know who these talkgroups belong to?

Thanks,
KB3IPD

These are normal TGs with status bits:

17523 = 17520 (Sully Dispatch) with bits 1 and 0
17043 = 17040 (W. Springfield) with bits 1 and 0
17331 = 17328 (Reston) with bits 1 and 0
16947 = 16944 (Franconia) with bits 1 and 0

Take the TGID, divide by 16. Take the whole number part of that and multiply by 16. That's the TGID. (Or just AND the TGID with 65520 (0xFFF0).

All 4 are status bits of base TG's,
16947 is a crosspatch for base ID 16944 FCPD CH-6 Dispatch Franconia
17043 is a crosspatch for base ID 17040 FCPD CH-7 Dispatch West Springfield
17331 is a crosspatch for base ID 17328 FCPD CH-5 Dispatch Reston
17523 is a crosspatch for base ID FCPD Sully Dispatch

Some other talkgroups

Ok, here are some more that have started to appear when using "ID SEARCH"

and then this one which shows up as "723739-722605"

Any one else in Fairfax County picked these up?

You must have a Uniden scanner, those are I-Calls, the last 5 numbers are associated with the ID.

You got that post all to yourself. :) (I was away for the weekend.)
