• 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:

Sounds a lot like old pagers, which were all often on 454.450 MHz back in the day. Not exactly, but close. Also reminds me of city water telemetry, usually on 173MHz.

But on FRS? Who knows. I've heard of some dog training collars and whanot on those freqs. Or perhaps Garmin Rino units TXing data to each other.

maybe.............

sounds like RTTY. also sounds like the " handshake " between two fax machines, but it can't be that because that go's over a hard line. do you live close to a hospital or some kind of medical place. i'm talking within no more than 4 to 6 blocks ? you hear alot of those types of noises over general coverage radio.
