<font size="-1"><font face="Courier New, Courier, monospace">After
checking all software settings and finding nothing obviously
wrong, I tried a database reset. This also had no effect on the
problem.<br>
<br>
I then shut the system down and removed Excalibur and ran the
system without that module. Again, no change - problem still
apparent.<br>
<br>
I reinstalled Excalibur but in a different board slot and low
and behold, the problem is fixed.<br>
<br>
I noticed that there is a green LED illuminated on Excalibur.
Can't say for certain if that was illuminated when the module
was in the previous slot. In any event, the problem seems to be
fixed.<br>
<br>
Thanks for comments, suggestions.<br>

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>
