Good point, Tony. You missed the "calibrated s-meter" in my post though.
No antenna on 20M - S3 With antenna, no sigs - S10 50uV from the XG2 - S9 73, Mike N2TK, Tony wrote: > Maybe the S-meter needs to be calibrated as per the manual after the RF Gain > test? > With no antenna attached on 20M I get no reading on the S-meter.
