[RFI] 6m spur

[bill steffey]

I also bought one of those nice looking FM transmitters, wanted to 
forward stuff to my 12 acres while tractor mowing..

Put a spectrum analyzer on it ...  wondering how clean.


What I found was a signal in the aircraft band MUCH stronger than the 
carrier in the 90 mc band.   Would not have been a good idea to put this 
on an antenna!!!!

made it gone....
