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.
