This is an aspect of the Orion II which beats the present K3. When one

moves across a frozen display in sync with the VFO. Once one stops tuning
the VFO the display is no longer frozen. It does help in

Transfer loss is loss from the K3 ANT input to the KXV3 IF OUT. -18 dB
sounds high...as though you may have an older unit

The frequency display is not always simply MHz and kHz. It all depends ...

I've noticed that when you reduce drive power so that the 10W amplifer is

be produced.
I did an EEINIT on the advice of Gary at Elecraft and now my transfer gain is
