        Hi all,

        Well finished my AT-11 in 5 hours and 45 minutes. Applied power
to it and it worked first time.

        Ran into the same problem with the connector but tried a
different technique. I pressed the connector tightly against the holes
and flowed solder thru the vias to the connector. I made sure the
connector had a solid flow of solder where the pins contacted the holes
and that worked fine.

        I calibrated the unit to a 50 ohm load at 3 watts and it worked
fine. According to my swr bridge I have very little if any return loss.

        I did try hooking it up to my G5RV with Amidon 4:1 Balun and the
tuner didn't like the match. The best it could do is 5:1 SWR. Has
anyone else tried the tuner on a ladderline balun antenna? When I use
my SLT tuner I can turn the antenna to 1:1. I also have a Diawa tuner
and I can tune the G5RV also to 1:1.

        Could someone tell me what I am doing wrong???
