Montgomery County Fire and Police were using some talkgroups on the 800-MHz Apco-25 digital system... I'll have to go to the radio and look it up... think on the fire side it's called 75-something... it's one of the "special event" or "major event" talkgroups or something like that.

> 467.6875 [ 97.4] Parking
> 469.5000 [ 88.5]

> This year I plugged them into my scanner (Alinco DJ-X2000) to monitor

> with a 70 cm super sensitive five element beam and a Win Radio 1500e set
> up (one person asked me if I was connecting into the internet!).
>
> The three I found were:
>
> 467.7500 [110.9] Channel 5 (?)
> 467.8000 [136.5] Channel 3 (?)
> 467.8700 [?] Channel ?

> I tentatively assigned the channels as I caught the personnel referring to

> available, I received no hits I could ascribe to the missing channels.
> All monitored traffic I heard seemed confined to these three frequencies

> Using my Win-Radio 1500e to scan the 450 - 470 band I did not see any of

> The fourth frequency I registered was FRS Channel 12, 467.6625 which was
> used for parking control. As my scanner is set up for all the FRS
> frequencies, I was surprised I did not hear any general fair goers use the
> FRS for communications, e.g. families, groups.
