L6 is good, it measures 1 ohm. But I'm seeing only 1 to 4 ohms from min to max RF gain. That tallies with what I'm hearing- the RF gain has almost no effect on received sigs. So I'll look for whatever is pulling R1 down. Thanks again- it always helps to have a second set of "eyes". 73 Bruce N7CEE _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
