[HBQRP] N3ZI counter kit

[kc0pet at embarqmail.com]

I have one of these that is in "half built" status as a stand alone frequency counter.  The price is definitely right.  I am adding a rotary switch for range and I think there are a couple of push button switches that will be on the front panel.  Anyway hope to put a write-up on my web site when finished.  

If I remember right I think the counter needs 100 mV input.  For lower level signals an RF pre-amp is needed.  I also have a pre-amp in "bag of parts" stage that I am going to build into a seperate enclosure as a more modular approach, but one might consider putting a pre-amp into the counter unit itself.

Jim, KG0RD was asking about a Freq.  counter kit that he thought I had at the last HBQRP meeting.  In actuality it was a AVR microcontroler project that used AVR-BASIC compiler to program..
BUT I see N3ZI now has a very inexpensive ($18-$27) Freq. Counter kit available at

which might be what Jim is after.  I thought that I would pass this along to the group too, asit would be handy for a test instrument, or its cheap enough that you could build it into a QRP project rig..
