• 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:

I know, in Orange County, at least that the PSAP's have headsets in which the local dispatcher talks to the Central dispatcher or call-taker. Is the voice communications done over radio frequencies, and if so, are they scannable?

I know that Wallkill PD has a frequency that says something to the effect of 911 link. Does anyone know of any others?

No and no to both questions. The connection between the two centers is performed over dedicated ringdown lines.

All that "link" is a UHF (460.275R, 411) to VHF (159.135R, 118.8) crossband. The only other similair one I know of in the county is Crawford's (453.8125R, 0-01-115 to 159.135R, 118.8).

Thats kind of what I thought.

Why though, does Wallkill need the cross band? If I recall correctly, Wallkill has a 100MHZ radio in their cars, for the sole purpose of hearing the polling channel.
