Last night I attempted to chase a few POTA ops with CW my QMX Low Band, version _023.? I noticed that the dial frequency on my QMX to be 1500 Hz higher at 7.048 than the posted frequency on the pota.app web page at 7.0465. Curious, I got out my 40M QCX-mini, which has been calibrated with GPS,? and found the posted frequency to be accurate.
?
Before I attempt to deduce the TXCO offset to bring things into order, I'd like to ask if:
a) is this a result of some configuration?
b) has anyone had such a major offset with the TCXO? Seems very unlikely to me.
c) it's curious that the offset is 1500Hz - the WSPR offset
d) has this been introduced somehow in ver _023??
?
The QMX is set with an out-of-the-box ver _023 configuration except:
1. The Audio/ CW Filter has been changed to 300Hz @ 700Hz?? and the Auto-offset/tone has been set to Yes;? and
2. Sideband has been changed to LSB
?
I have not attempted a re-install of an older version and did not notice any such frequency offset before now.
?
Ideas anyone?
