I need to do some more testing as some of my bench numbers look like they might be better than Jim's.
TP 1 @ 7.150MHZ 700uV gave 0.1 p-p
TP2 " 200uV gave 0.1 p-p
TP16 took like 300uV to get to 0.1 p-p, so a lot more
TP17 took much more like maybe over 2000uV.. have to go back and measure.
(It might be my signal generator doesn't get close enough to the BFO.. have to try playing with it a bit more).
