I need a schematic for a Dosy TC-4001-P. I can not get the Mod function to calibrate on AM mode....I run out of dial before it gets calibrated... seems to work ok on ssb. Has anyone ever had this problem??

Buck I have had that problem twice and all I have done is check my connections to the meter, turned the radio off then on, and each time it worked

Have you checked your pl connectors? I find that one bad connector, it will not operate correctly. That would be one place to start.

Buck,

I have the 4002PSW meter. On mine, I must have the radio deadkey no lower than 4 1/2 - 5 watts or it will do the same in all calibration/set modes. I'm lucky I have variable power to turn it up and down. I set it that way.

I don't have the answer but a similar experience with a similar Dosy.
