Most things seem to be working. Went through the RF alignment today, a
few of them were way off. Gain over the range is now more consistent.
The meters I have for it are aftermarket and I need to make some
adjustments for the Carrier meter. The VU meter I had was not working so
I stuck an old one I had in. It seems like all I need now is the 15.5MC
xtal and to see if I can get the osc levels a little higher on #2 and
look into the high level on #1. Prolly tubes will do some of that.
Line/local level is working fine. Then I'll see about that carrier pot
adjustment mod. They are both picking up WWV on 10MC the same now but
there's a lot of static. #1 seems to have more static than #2, might be
a noisy tube in it.
