[Elecraft] VCO Alignment

Bob:

You have a definite problem in the PLL Circuits.  The PLL Circuits are on 
the schematic of the RF Board Page 1 of 4 and is everything on the top half 
of the page.

You need to check all the componets in the PLL circuit.  It appears that the 
PLL is unlocked in all but three bands.  Any reading near 8 volts indicates 
an unlocked condition.  It appears that the only bands that are in a locked 
condition are 80 - 40 -15 Meters.  The rest are not in lock.  One of the 
major problems can be the wiring of the Thermistor Board.  Also make sure 
you have the coreect diodes installed in D17-D26.  Make sure all pins are 
soldered on K13 - K14 - K15.  Also check the resistance across RFC15 and 
make sure it is not open. It is very easy to damage it while installing it.
