[Boatanchors] Hand held frequency counters?

[Jim Wilhite]

Chuck after posting that I went out to the shack and hooked my 259B to my Singer digital sig gen.  I set the output to 0 dB and ran the frequency from 1 Kc up to over 290 megacycles and it read the frequency correctly.  Dunno, but it worked very well at 0 dB and accuracy was well within ~5%.

I bought mine in 98.

  Jim,

  The 259B "manual" I have only says "The sensitivity of this port (freq.counter input) ranges from 10millvolts at 1.7 MHz to 100millivolts at 180MHz.  The freq. counter is not design (sp) for use below 1MHz."  (My experience with MFJ is that they are stingy on schematics and specifications)

  I've never tried it as a freq. counter.  I use an Optoelectronics handheld that must be 15+ years old.  Still does a good job.  The bench counter is a B&K.

  Happy New Year All...............

Does anyone know what the count range is for the MFJ 259B?  It is in the 
260 dollar range and can be run with a wall wart so you would have a 
full time counter and much more.  I can't find the specs anywhere for 
the counter.
