[Yaesu] FT1000MP RF Feedback?

[Bill Morris Denton]

Steve I have the Same exact problem with my FT-990.  Have a friend that had 
the same problem with a Kenwood TS-450. He wound several turns of coax, like a 
choke on a beam antenna, and inserted it between the 450 and the external 
tuner OR antenna and it solved his problem.  I have not tried it with mine.  My 
situation changes with different antennas.  Some bands there is no 
problem at all.  Others I have to turn the external speaker off while I,m 
transmitting. It's usually worse on higher bands.
The strange thing is, it doesn't get into the transmitter audio.  I'm 
going to try the coil of coax tonight.
