mfj 969
 

Hi folks

Blew my 969 tuner and purchased both boards from MFJ. However there are no
calibration details with it. Anyoe has experience calibrating an MFJ 969?

Any details appreciated.

I went through the calibration of my 949 recently by borrowing a buddy's Bird wattmeter and connecting it
in-line with my 949. The adjustment pots are easy enough to figure out from the silk screening and schematic.
I also used an external dummy load as the 949's resistor was outside the 5% tolerance. Easy enough to do with
good results and the only differnce between our units is a roller inductor.
