• 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:

???? If you mean an echo, it can happen when someone is transmitting, and another radio is receiving the audio at the same time and it's inadvertantly being picked up by the mic (for example, if 2 people were relatively close to one another...) There's a very slight delay in when the audio is processed by the controller from the 2nd source, hence the echo effect. I've seen this happen on occasion on the ham bands, too.

I hear it on AA's system also, it seems to happen very intermittently. It sounds like a train whistle in the distance.
