Does anyone know where I can find detailed alignment instructions for a MFJ-259B?
I bought some Vishay precision non-inductive power resistors - 25 ohm, 50 ohm and 100 ohms 100 watt rating to use as dummy loads. I assembled them to a proper heat sink and connected to an SO-239 with zero length leads - and when I tried my MFJ-259 with these resistors, it told me that these resistors were OK only up to 10 MHz or so!!! At 30 MHz, the 50 ohm resistor read 62 ohms with a reactance of 10!!! Given the specs on these resistors (flat to at least 170 MHz), I now tend to disbelieve my MFJ-259 and would like to calibrate it. I have the instruction manual that came with it and it is not adequate for a calibration task. 73, Don W3FPR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
