    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 not seen it noted that when Washington Center RCAG site at Bucks Elbow combines the Montebello (121.675) and Azalea Sectors (135.4) when traffic is light enough to allow, each frequency acts as a repeater repeating not only Washington Center *but also the aircraft that was on the other frequency*. So if you are within range of hearing Bucks Elbow and you hear an aircraft on 121.675 or 135.4 at these times, it may actually be transmitting on the other frequency. (If you listen to both, you can usually determine which frequency the aircraft transmitted on as that will generally be stronger.) Essentially each frequency acts as an input to the other; of course some logic circuitry is necessary to avoid a "feedback effect". The UHF frequencies (263.1 and 284.7, respectively) are also simultaneously transmitted.
