Is there an adjustment pot on the MFJ259b for the freqency counter and

this may or may not help, but at the site,
http://www.mfjenterprises.com/produc...rodid=MFJ-259B they have a
link to "calibration instructions"

The original 259 has the counter on a daughterboard. There appears to be a
trimmer cap on it. Adjusting it is another matter, but it might be
possible to drill a hole in the main board to allow access to the trimmer.

Disassembling the 259 is non trivial, but easier than putting it back
together.
