Flex 6600M Display lock up


During this past weekend's contest I experienced the following problems:

  1. On occasion the display on the 600M would "freeze" and lock up. I could still tune (by ear) and N1MM tracked the VFO but the display would stay frozen. It would sometimes recover and then lag behind the VFO. Changing bands also resulted in a long lag before the display caught up to the band change. A reboot of the 6600M would fix the problem, but it would then reappear. My guess is this is an issue with the LAN (I had spots displayed). I have high speed cable internet fed from the router using about 15ft of fibre to a DLink 16 port unmanaged switch (metal case DSS 16+). this has happened in the past using N1MM, but was persistent this weekend.
  2. Rapid tuning would result in the TX signal not matching the TX frequency on the display (the tuning indicator would be accurate and I could complete the Q, but the actual TX "spike" was several Khz away from the frequency). Resetting the size of the display or centering it would correct the problem. This would only appear if I tuned rapidly from one end of the CW portion of the band to the other. I have this problem using N1MM or DXLab.

Any ideas?

    Did you try changing the Display settings to reduce the bandwidth required on the LAN?

    Good thought. I did not and that would obviously assist. I will try that.

    Thank you.
