<font size="-1"><font face="Courier New, Courier, monospace">I have
an Atlas system (Metis, Penelope, Mercury, Excalibur).<br>
<br>
I have recently noticed that the TX frequency is slightly high.
On 40m, it is approx 70Hz high, on 20m about 140Hz high. RX
frequency seems to be fine as verified with WWV and also
external Elecraft signal reference on 7040KHz.<br>
<br>
I have verified the unwanted TX offset via another radio
(SDR-1000).<br>
<br>
I can correct for the offset using XIT.<br>
<br>
The internal oscillator is linked to Mercury as shown in the
setup screens.<br>
<br>
I'm running latest PowerSDR Mrx and firmware and using Windows
10.<br>
<br>
I recently upgraded to latest powerSDR. At that time the
upgrade installation procedure was able to apparently
successfully import the existing database (although I was
expecting to have to do a full manual database setup). The
previous install was 3.3.9 IIRC. I do not know if the TX offset
was present with that version.<br>
<br>
Any ideas appreciated.<br>
