[amsat-bb] S Band interference was RE: Re: Field Day mode for AO-51

[Gary "Joe" Mayfield]

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.

73,
Joe kk0sd

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
