Fairfax County Public Safety unidentified TGs

[n3ijw]

After several weeks of monitoring the FFX county TRS with MTrunker and getting to the point where I'm seeing 552bGrp.txt in my sleep (or nightmares, rather), I've compiled a list of talkgroups that I haven't been able to identify.

Here they are in hex and decimal:

0010, 16
1fe0, 8160 <- this one pops up on the control channel from time to time
3ea0, 16032 - Motor Ops 1 aka MOPS-1 (thanks freqhopping)
3ec0, 16064 - Motor Ops 2 aka MOPS-2 (ditto)
3ee0, 16096 - Motor Ops 3 aka MOPS-3 (ditto)
3f20, 16160
3f40, 16192
3f50, 16208
3f60, 16224
3fe0, 16352
4000, 16384
4020, 16416
4680, 18048 - Hospital?
4a30, 18992
4db0, 19888
4dc0, 19904
4f10, 20240
4f50, 20304
4f90, 20368
5090, 20624
52e0, 21216
5300, 21248
5320, 21280
5380, 21376
53b0, 21424
53c0, 21440
53d0, 21456
53e0, 21472
53f0, 21488
5420, 21536
5520, 21792

If anyone can identify these talkgroups, or simply point out where I'm screwing up interpreting trunker data, I would be grateful. Thank you.

18048 I heard once. I heard the words "conference" and "Med Com". One of the hospital TGs apparently.

I submitted these a while back. But it seems someone knows better.

I've found others, usually encrypted, thus identified that I did not submit.

I don't know about the rest. My BC250D no longer wants to search trunked systems and stop on active TGs.

I take that last bit back. I just checked my settings. The 'I-call Only' was selected. Didn't realize it was or that it would cause that problem. Time to start searching.

I know a guy with the SO. I'll have to see if I can squeeze any good info out of him.

Trunker is some pretty cool software, ain't it?

Thanks a bunch, leonzo. What are those last four Alexandria TGs used for?
