I have been trying to figure out what frequency Hagerstown City Services uses on UHF. The city is licensed on both VHF and UHF. I know that Lights, Parks, Water, & Streets all use VHF. And they drive white marked pickup trucks around that have obvious 18" VHF antennas. But there are quite a few of these marked city pickup trucks that have shorter, probably 8-9" UHF antennas as well. I know that the city has some channels up there. Here's basically what I've been able to gather so far:
There is a long-standing license for KNEX271 on 453.150 and 453.650. The only user on 453.650 appears to be the County Commuter Buses with a tone of 123.0 PL. However, I have concentrated some attention on 453.150 and found some interesting things.
There appears to be a repeater up on Fairview Mountain for 453.150. I am beginning to think that it is PL-independent, that is, that it will repeat all traffic w/ input of 458.150 regardless of PL, and that it will pass the PL along. This may not be true, however, as I'm still trying to determine if all of the traffic I'm hearing on 453.150 is going through the repeater.
I have heard Airport trucks clearing off the runways at the Regional Airport on 453.150 w/ 103.5 PL. I have also heard 453.150 w/ 77.0 PL referred to as "Local Government Talkaround". Other users of this frequency have been found using 67.0 PL and 71.9 PL. And it's possible that the talkaround channel was referred to as channel 16, implying that they may have up to 16 different channels in their trucks (it would kind of make sense to have the talkaround channel as the last one in the radio anyway).
If anyone knows anyone in the city who would be willing to let them check out the channel lineup in their trucks w/ frequencies and tones, or if anyone has any information on this, please post it here. I doubt that there is anything especially interesting to hear, but it bugs me that they all sport UHF antennas and yet they seem impossible to find on the radio. For the record, I have searched 451, 452, and 453 MHz and cannot any users among those frequency ranges that would match up with the county government trucks. Maybe someone knows what jobs or responsibilities these trucks w/ UHF have and can add this information as well. Thanks for any and all response.
