After making all of the recommended changes, I hooked up my MFJ and got
650 readings regardless. When connected to a 75 ohm dummy load, it
reads completely normally, as does shorting the input (R=0_ If I had
managed to damage the MFJ with DC voltage on the input, would you expect
no readings

I would like to know which diode because mine is doing the same thing.
There is nothing in the manual on how to calibrate it either.

I would like to know where to get those diodes! Right after I bought my
last MFJ-259B, I e-mailed MFJ about buying a spare or two just in case.
They never replied.
Anyone have a Mfg. name and P/N?

Is no one going to suggest that a ³gyrator² should be put into the circuit
instead of an inductor?
There was a W3 who had some of the diodes for replacements. They are
surface mount and small! Obviously, one wants them to have a very low
conduction threshold voltage. I suspect Tom can suggest
