[Kenwood] TM255A

[zl2aaa]

Hi All I have a TM255A which has a problem with frequency stability.If tuning
in one direction it will jump frequency either up or down also in transmit mode
it will transmit on one frequency then return to another receive freq .It would
appear as if the pll is unstable .Has anyone had this problem or know of a fix
as I have only the circuit diagram and no service manual Tnx Morrie
