[R-390] 390-A alignment

[Paul H. Anderson]

Howdy Folks,

I was aligning an EAC 390-A last night, and ran into two things I want to
ask the list about.

Firstly - the calibration osc reads about 20dB on my carrier meter across
many bands pretty consistently.  In the 3MC band, it reads 0 dB.  I can
use the BFO to determine that the signal is still there, but it is weak.  
2MC and 4MC are strong.  Also, the bands above about 19 are similarly
weak.  What gives here?  Is this a sign of mechanical misalignment?

Secondly, when I attempt to peak the trimmer on Z503, the diode load
voltage doesn't change at all.  I think I'm following the manual correctly
- is something busted, or is it just real flat?

Thanks in advance!

Paul
