Transmit Delay With PGXL/6400

edited November 5 in Power Genius XL Amplifier

EDIT: I turned the amp off for a few moments, then back on. All is well again. Guess I'll have to turn the amp off after a day's operation, but that's no big deal.

Trying to operate the Sweepstakes CW contest. However, when I go to transmit, whether with my Begali key or the CWX (F1/F2, etc), the transmitter starts sending, but the PGXL doesn't kick in until AFTER the W in my call (W8ASA). So, the other station gets 8ASA every time and has to ask for repeat. I initially solved this by sending twice, but that's not the answer, I know. It only started doing this today.

Sometimes, I'll just hit a quick Dit and send my full call after I hear the amp kick in.

Latest firmware all around.

    Ideas? - Yes, Flex has to fix that bug.

    It appears once in the while and like you already figured it out, PGXL power cycle fixes the issue.

    Same issue here. I tried adding a space in front of my call in CWX. Did not help, so I added an 'e' before my call to wake up the amplifier. Not an issue barefoot with my 6600, only with the PGXL. At first I thought it was an RFI issue, but it happened into a dummy load and at lower RF power settings on the PGXL. Tried QSK and various Delay settings but no change. The 'N' was always clipped. Added Mix31 ferrites everywhere.

    SmartSDR v3.5.9

    PGXL v3.7.32

    update the amp to 3.8.4

    Try this. Use 30 ms TX delay. Set CW delay to 30 ms.
