Steven,
What kind of numbers are you seeing for the Clock offset..
especially cold to hot.. I would expect that the variation would be
in the range of no more than +-30 units...
I don't have the 3k but the 1500 and 5k are quiet stable..
I sounds as if the DDS clock is not locked to the internal reference.
Have you tried a DB reset to factory defaults and then just a reference
calibration?
Have your tried manually adjusting the clock offset ( in case the auto
cal is failing) ?
Sounds a bit like it could be a hardware problem..

I am running PowerSDR 2.2.2 BETA on Windows 7 64. Radio is a Flex-30000
I never ran the frequency calibration before yesterday.
I have had an email exchange with a fellow flexer on this but I am
still having questions.
Every time I run the calibration from PowerSDR Setup> General>
Calibration I get a different result for the DDS Clock under General>
Hardware Config Clock Offest.
The rotation in the Phase display never remains non rotational for
long after I do run one.
The reason I got into this was I wondered why my ORG in WSPR was being
reported quite a bit high by everyone. I was transmitting at 10.140260
yet many stations reported me above 10.140280. Now I know that some of
those stations are not spot on on RX either but some of them should
have been close. Once I ran the Calibration some did get pretty close
to being spot on which is what I would expect.
Now the reason for the different result from different calibrations
and the rotation of the signal in the Phase display after adjustment
has me worried something might be wrong with my Flex-3000.
Quite frankly I'd go into withdrawals if I had to do without PowerSDR
for more than a few days if I had to ship it back to Austin. I also be
worried the whole time it was gone.I don't trust shipping companies or
that they would quickly replace my rig if they damaged it or lost it
in route. I don't have the money to replace my F3K or to fight with
shipping companies to get my damages covered should something happen
if I did have to ship it and something bad happened. The last radio I
shipped Texas was returned with a nice big hole punched onto the
factory shipping container and it was quite a bit more substantial box
than the box my F3K came in.
