QSL Lyle, I think what it all goes to prove is what a good front end the XV50 (not KXV50 as in my previous) has. The only problem I see here with having a pre-amp connected to the KXV3 is that I also use the RX ant input for a HF receive antenna. I suspect that I would need to implement some external relay switching for that.. 73 Stewart G3RXQ > _______________________________________________ > Elecraft mailing list > Post to: [email protected] > You must be a subscriber to post to the list. > Subscriber Info (Addr.
