[Boatanchors] Hand held frequency counters?

[cemilton at aol.com]

 Jim,
 That's good news.  I've never really thought of it as a freq counter (even though I knew it had the input) but I will put it on the bench and see if it works as well as yours.  1kc to over 290mc ain't too shabby............. hi hi

Thanks es 73 de W4MIL

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.
