I just realized something that may be throwing it off - I installed the Elecraft 4:1 balun inside the rig and hard wired it to ANT 2 on the tuner after I'd done the bridge null - is it possible that that has thrown off that null and I am not actually getting a 50 ohm load to the front end? I'll have to redo that tonight and report back.
Thanks for the help so far. Tom On Sun, Jul 19, 2009 at 11:12 PM, Don Wilhelm <[email protected]> wrote: > Tom, > > That is exactly what I said.
