This past summer I had been monitoring this LTR system:

http://www.radioreference.com/apps/db/?sid=3372

It covers a large area from Delaware to the Maryland mid-eastern shore.

The license actually includes these channels:

460.850
464.850
464.125
452.7375
462.53125

463.825 *
463.300 *
451.7875 *
452.2375 *
464.5875 *

* This year these five channels are carrying data (no voice).  The signal fluctuates but I receive frequent close-call hits on my Uniden scanner.  And when I get one hit, the next transmission will typically move to one of the other five channels.  It is almost as if this were a digital voice system because of the system usage and the fact it appears to be local mobiles.

Here is what it sounds like on the mobile input side:

I thought maybe DMR, but the output in this case sounds similar to the input which does not sound like DMR to me.

Maybe Eric Carlson can tell me what I�ve been hearing?

Any ideas?

Thanks,
Alan
