Now and then you may find an MCS2000 with a VCO that will not lock in the ham band. The following link provides instructions for how you can modify the VCO if that is the problem:
Greg, KJ6KO, has run across one or two that had to be done so far. He did one and the other was done by someone back east using conductive ink and worked fine. You might contact him directly for help.
