I'm in the Chicago suburbs, and can see at least a dozen wi-fi access points in my neighborhood with NetStumbler, yet I have worked AO-51 in mode V/S with a K5GNA downconverter with corner reflector, hand-held inside the house. With the barbecue grill antenna, I can use an in-line 6 dB attenuator AND the receiver's attenuator, and still have armchair copy.....

Joe,
My neighbors have several "wireless" devices that operate close enough to our frequencies to raise my noise level or produce a series of clicks and other noises. The worst offenders are a wireless network and a cordless phone. During the AO-40 era I bought a cordless phone from a neighbor that was very troublesome. I have since moved to a country location, and find it interesting that I can tell what direction town is by moving my antenna (pointed at the horizon) and listening to the noise level on mode S.

Hi Joe
Your comment about Mode S interference interests me I have not been on since AO-40 In those days there was no interference on mode S. Unless it was another Ham. Would you kindly explain?
Thanks
