My MFJ-259B was out of order in the end of the year 2001. Not the whole analyzer but a main function.
So I wrote in January 2002 an e-mail to MFJ Enterprises and ask the company for a schematic of my analyzer.
Wow!
Some days later I found a large letter with the searched schematic in my mailbox. Hooray!!
I thought that more user of this analyzer searchs the schematic, so I put all things here on my webpage.

MFJ-259 - Calibration

One month later a German user in Malaysia send me the copy of the same things for the MFJ-259B. Thanks again on this way to Gerald, 9M2/DL3KGS.

Many thanks to MFJ Enterprises for the fast service!
