Check the 25 volt DC input from the power supply board to the VCO. If that
voltage is low the VCO doesn’t have the range it needs to tune the 10 and 15
meter bands. If your power supply board is the older type with the dc to dc
converter, check the core on the transformer to make sure it hasn’t slipped out
of position. The voltage should be between 23 and 24 volts if I remember right.
