• 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:

The FD bandplan lists 2A, 2B as "TA 241" and "TA 242"....are these talkaround freqs? I cannot find anything corresponding to this in our database. Also, do we have TG IDs for FP 78 & FP 88?

Thanks much.

TG 78 & 88 are in the Database.

Yes TA 241 & 242 are simplex frequencies I dont know what frequency they are though.

78 & 88 are in the database....but they are listed as multiple incident fire TGs....whereas 99 is listed as a Fire-Police Common TG. Yet, the fire radio bandplan shows 78, 88 & 99 as all being F-P TGs. Maybe the database needs to be updated/clarified if all are truly FD to PD in nature. Our current police database listing doesn't cite 78 or 88.....maybe these have been programmed into the police radios recently?

Dave, I heard PD using TG 78 tonight for a traffic detail in Northpoint following a fireworks display. It is the same TGID as before, I guess they just programmed it into the PD radios in addition to having it in the FD radios.

Thanks, Mo....that's good to know. Submitted the new designations of FP 78, 88 to the database admin folks.

The talkaround channels "241" and "242" are simply two of the trunked frequencies, on the high side, in simplex mode; I'm not sure specifically which two. The reason I know this is because we tried to use 242 in a dead spot one day, and every time we keyed up, the radio denied the transmission and unsquelched, revealing transmissions from the trunked system.

Back in the time of the STX, PD had talk-around channels too, and they were also simplex mode of a handful of trunked channels. I don't know if the new PD radios have the talkaround channels or not.

hey all,
I know I'm a dinosaur when it comes to this info, but when I used to work for BCOPD we had 78 and 88 as IAC 78 and IAC 88. We also had talkarounds TA 246 EST and TA 247 WST. The TA's were used occasionally at special events but other than that they were pretty useless. I have no idea what frequencies they were though, unfortunately. These were all programmed into the MTS2000's along with other TG patches to surrounding systems.

hey dave,
things are going great out here, its been a bit hot lately but thats the worst of it. Just wanted to pop into the MD forums to see whats changed since Ill be back out there for about a week. Hope that info above helped. As stale as it is, it dosnt look like Baltimore Co has changed much up with regards to their TRS.

Mike
