frequency counter
 

have a look at the unicounter by ron stone in qst.
when i first saw it (a 1-digit freq counter) i thought what a useless
idea!!!!!
when i saw a morse person in the radio club enthusing over a morse freq
read-out i went back to the uni-counter
read it again, made one, and then e-mailed ron s to apologise for writing
off his handy-work so unjustly!!!
it is SUPERB!!!
