[Kenwood] TS-440S issue

[howard holden]

Have subject unit. Issue with operation 22Mhz and up, dots only. Adjusted VCO1, coils T21-T24 per the service manual. Monitoring voltage at TP10, T21 voltage sits at 2.11V, not adjustable. T22 23 and 24 all adjust just fine and unit works well 21.999Mhz and below. This is a later model from what the original owner told me (SN 8010002). VCO1 has no glue in it, no signs of any having been cleaned off.

Has anyone encountered this problem, and if so what was your fix?
