Ebay Frequency Counter Board
|A frequency counter is
a great asset to any shack but they can be quite pricy. My old
Thandar FT-200 gives great service but its only good to 200Mhz. My
project to build a DMR repeater for GB7AY required something capable of
doing something a little higher.
I found this on eBay and found it to be really good value and surprisingly accurate.
A cheap instrument case also from ebay and it starts to look the part.
A word of warning though as with all frequency counter do not connect them directly to an RF source or you will burn them out. I use a isotee isolator made from a SO23/PL259 Tee coupler. You can find out details hoe to make one here:-
