Roland,

Are the other bands still the same as they used to be?  The high voltage
indicates that the PLL is attempting to reduce the capacity of the
varactors - which means that there is too much capacity in the VFO circuit
somewhere for those bands.  Check the value of C73 - it should be marked
'470'.

The only thing that is common for 30m and 15m is C73 (also common for 40
meters if the K60XV option is installed).  Go to the secondary menu and be
certain the D19 parameter is set to OFF.

You might check for solder splashes in the vicinity of Relay K13.

73,
Don W3FPR
