He must be a CW only guy.

An  ex-Pegasus (now FlexRadio) user has told me that he attenuated RF 
feedback  from an antenna in close proximity by bypassing his mike input 
line to  chassis ground  with a 100 uH RF choke. 

Has anyone else tried  this?  What, if any, were the results?

Many thanks and  73,
