• 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 have just picked up a Pro-197 scanner and I have my local system programmed in it (Central Maryland Radio Committe 700 MHZ APCO-25) the radio will scan and stop on a channel, I can see that it is receiving something but I cannot hear anything. The signal master jumps around (it doesn’t stay steady on a certain reading) I know the speaker works, the radio will revive stations just fine when I turn the volume up I just hear a light hissing sound.

Pro-197 Is Phase 1 I Believe MD 700 Is Phase 2.

Good Morning 1977addis. If you are familiar enough with the Pro 197, you may want to consider running a Limit Search for say, 768.0000 thru 775.0000. If you do that the 197 is great for landing on any control channels that lie in within range of your system. That will give you an excellent idea of what you can receive and decode, and what you may not be able to. It could simply be that the transmitter is just a little far away to receive all of the data, most likely an encryption though. Hope this helps, take care up there
