• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

RRDB indicates that 154.3925 is a Dispatch Patch. I have monitored that frequency numerous times and never heard anything on it. Does anyone know if it is really used?

If it is not being used now; it will start to be used in the near future. It is part of their radio system upgrade. It is my understanding that the 154.3925 frequency will replace their low band (33.820) station alerting/minitor pager frequency.

I've monitored it from Hollywood in St. Mary's County and had it full scale on a desktop scanner, regular antenna nothing fancy when the techs were doing testing on it about a week ago doing a bunch of number counts back and forth with the same PL as listed in the database. I'm curious as to what they were doing.

Umm testing it to make sure it works, when buying a new radio system, everything has to work before it can be accepted by the agency that is purchasing the radio system.

I drove through Calvert yesterday. 154.3925 was silent / not simulcasting their fire dispatch TG on their current SmartNet system.

Another note: the RRDB lists TG 2512 as "Fire Co Trng / "Ch. A10 County Training," but was carrying radio traffic that sounded like Parks and Rec.

They haven't switched over to the vhf high simulcast frequency as of yet. Simulcast of their dispatch TG occurs on 33.820 pl141.3

The Training channel was probably being used by one of the companies at a special event like a carnival or concert.

I've noticed increased traffic on this frequency. There is some fire department patched to it but it doesn't sound like anyone local.

If you're not using the PL tone, you may be hearing the Baltimore City FG simulcast freq. 154.385. It does bleed over

Good call but I'm using a PL tone. Yesterday there were radio checks being conducted. They were somewhere going room to room giving a room number and an indication of signal quality.
They were doing the same with the 800 TACs a few weeks ago. Why they are testing frequencies meant for mobile on street with portables in building, IDK. Maybe testing some BDAs?
