[Elecraft] KX3 birdie for my other radios

Stan,

Just set MENU: RX ISO to ON. This turns on the isolation amp, which  
should knock down VFO leakage out of the mixer by 70-90 dB.

We don't turn the isolation amp on by default because it adds about 15  
mA to receive current drain. (This same stage is also used for the 10-  
and 30-dB preamp settings and the attenuator, so if any of these is in  
use, RX current goes up by 15 mA.)

73,
Wayne
