Just built and have used my KX3 for a week now.
Yes I'm loving it and am already thinking of selling my Orion II for a K3.
BUT.... when listening with a couple of other radio I'm hearing a pretty strong
signal being put out by the KX3 700 kz above the KX3 tuned frequency.
I just aligned the filters and am thinking it must be something I left on during
that. It only is there with CW.
It is easily seen on my Orion II band scope.
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.)
