This was not a QSO at all. It was simply a one way transmission from a signal generator at my end to a receiver at his end. No QSO was attempted. > Now to your question.

Now I don't yet have the 1 Hz option programmed in, and it might well change the behavior completely, but I'd still like to find a way, if one exists, of checking this with the equipment I have. The signal generator is no longer supported, but I could try my luck seeing if there are any known problems with this unit, or firmware upgrades available - currently revision 29, May 1991. > But I don't think so.

I also know a lot of people run portable stuff on 10 GHz, where achieving frequency stability is more of a challenge, although less so with GPS. But this is a laboratory instrument, from a reputable manufacturer. I personally would not expected this behavior. I actually purchased this very cheaply (£650 GBP, which would have been about $900 at the time), but they are not cheap to buy now.
