Re: Tracing receive signal for low signal

Yep that was a great suggestion by you.  Those measurements were at VOL- high.

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.

Just as a suggestion ..Use the "VOL-H" point as a reference on testing rf levels ...that way both the V3 and V4 boards will be applicable
