• 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:

Why do air traffic controllers and pilots never say the third number after the decimal? I.e. they say "Contact Detroit approach on 124.97." when the freq is actually 124.975. Are they really in such a hurry they can't spend another second saying the last number? Or do their radios have different numbering schemes that prevent them from adding the third number?

When the controller tells me what freq to switch to, they leave off the last # because it is assumed that the radio will automatically add the 5 at the end (it always does) and to speed up radio communications. Check out this brochure that has a great image of the front of a Com Radio!
