Hi Scott,
Sorry.
As it turns out, after double checking, I have the opposite problem! The KPA500
follows the K3 just fine but the K3 will not follow the KPA500. A press of the
band buttons on the KPA500 has no effect on either the KPA500 or the K3.
Strange, no?

The MV89A is pretty incredible-- especially for the price.

It isn't basically "on frequency" from a cold start. It drifts 10's of

Thanks. That is exactly how I had - and have - it set up, and it worked fine

Yes, I bought one as well, along with the matching 8 channel distribution

Are you using the Elecraft USB adaptor lead? I ask because initially I was

Moving to using the Elecraft USB adaptor instead cured that. As a

Hoop,
I do not have that Fred Cady book, but I would think that is intended
only to switch between the K3 and the KX3 when both the K3 and KX3 are

If you want to operate the KX3 with the K3 powered off, you can remove
the cable from the K3 ACC connector.
