• 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:

Can someone tell me if all of the talkgroups are cast across each site? Or is Bedford across Bedford only , Amherst across Amherst only, etc?

Thanks,
Todd

there are a few talk groups that can be heard over different sites other than their own ... for example, when I'm listening to the Lynchburg site I can hear Bedford Sherrif, Bedford Fire, Amherst Sherrif and a couple others ... I don't think you can hear Lburg PD from any other site than theirs tho ... I don't have my scanner with me bc I'm at work, but I can post some more "cross-site" talk groups later :) and, I'll actually be in Lynchburg this weekend so I'll take note of as many talk groups as I can that do this ...

edit: just wanted to comment on the fact that this system is at the very top of my list of favorite systems to listen to and monitor ... IMHO it is awesome and they did a great job on it :cool:

Sounds great & thanks for your help. We're going to SML next weekend so I'm getting my scanner ready.

I think the system works like most wide area systems. In other words, if a mobile/portable radio "affiliates" with the system on a particular site then it will repeat all traffic for that radios selected talkgroup on that site. In other words, if Lynchburg PD is not normally transmitted on the Bedford site but a Lynchburg PD mobile unit drives through the Bedford sites area it will start transmitting the Lynchburg PD talkgroup. Each radio is set to "affiliate" with the control channel when turned on and channel is changed. That way the controller for that site knows which channels it needs to rebroadcast.

You hear some talkgroups on adjacent sites since they have mobiles/portables that are close to the border and therefore there are some units affiliate on each of the adjacent sites.

Anyway, that is the way it appears to work. I know that is the way Motorola wide area systems work.
