• 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:

SQUARE ROOT OF 30,000 FT X 1.415 GIVES LINE OF SIGHT DISTANCE. Using 40,0' the MAXIMUM distance would be 290 miles. This will only give you an idea of the distance.

Ever heard an unknown A/C,but it was loud and clear?? A/C passes Altitude as 35,0. Us this fornula and it will give you an idea how far from you they are flying. I once monitored J-STARS at 40,0 over Ft. Campbell,KY.

... this is not always true... I have been at 28k and 120-130 miles out and had problems... I will also say that from air to air distances have been achieved well over 350 nautical miles
