[Elecraft] LineOut on transmit

[Richard Ferch]

What you are seeing is the monitor output, which is mono (both 
channels). To turn it off so that you do not see your transmitted signal 
in both displays, adjust the MON control to zero. Using MMTTY, you will 
still see transmitted signals in the left channel display, but these are 
generated in the software, not in the radio (MMTTY uses the left channel 
to transmit).
