Jeremy,
Since you now have 8 volts at the left end of R30, I would wait and see
if you can get all the band end R30 voltages into spec with adjustment
of L30 and the turns spacing of T5. If so, I would ignore the DC
voltages at U4 pins 1 and 2. Those voltages are partially a result of
just where within the 10 kHz range of the PLL reference oscillator it
happens to be.
I am glad to hear that you now have it working within a reasonable range
- good work.
73,

Thanks Don,
I'll rewind T5 and see where that gets me.
U4 pins 1 and 2 are still low (no change), and U7 pin2 and U4 pin5 are
equal. Do you still suspect there may be an issue with U4?
