• 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:

The weirdest thing...using a telescopoic antenna on my handlhelds, I can hear both side of the conversation when listening to the civil air band. When I hook it up to the 130J I only hear the pilot talking no ATC's at all !!! What's the deal with that ???

Hi Path and readers,

It has everything to do with the radiation pattern of the antenna and it's vertical takeoff angle in particular. It gets complicated but the short form if maybe a bit innacurate is the discone's angle is higher and fixed by means of it's mount while the whip is obviously variable and somewhat wider (both higher and lower) by means of it's dipole like design. See the aircraft monitoring forum for a similar thread. I shoot a signal in the air, it comes to Earth I know not where. That depends on the trajectory of the aircraft I just shot down, I'll see the wreckage on the 5:00 News.

Colin, what's an "attunuator"? (;->) I think you meant "attenuator" but in any case your off the beam so come right to 180 and decend to 3,000 feet. Approach 18L 36R and call me at the outer marker.

Edited for humor and directions to the airport.
