CW transmission will be intermittent, video file is attached. Thank you.

Whenever I have CW sending issues, I do a shutdown, wait, and restart of the radio. That almost always solves the problem for a day or two.

Concur. More specifically, I always cycle DC power and not just a shutdown from the front panel.

I tried disconnecting the DC power supply and then switching it back on. After restoring to factory settings, the problem remains. The same is true for win10 and win11 system tests, which can rule out computer problems. I have tested almost all versions of V3 and the problem is the same.

Hmmm. Another thought…when you cycled DC power did you pause at least 30 seconds before turning it back on? I always do that because flex says that a background processor can still be running if the DC doesn’t decay sufficiently before you restore power. Otherwise, you may want to submit a support request. This is a common problem that’’s usually resolved by a power cycle. But apparently not in this case.

Yet another thought….Instead of using the internal keyer try using a straight key or an external keyer if you have one. See if the behavior changes.

Inexplicably, I feel normal again, and I'm also ****.😄

Great. Did you do something to resolve it or did the problem go away on its own?

Are you running 3.5.9 ? I believe this improves it, though it is not mentioned in the release notes; so it could just be the procedure below.

Also, here is the procedure I have found that resolves any cutout issues I was having:

Shut down SmartSDR if you are using it remotely.

Power down the Flex with the button on the radio.

Wait at least 30 sec AFTER the lights go out on the Flex.

Turn off the 12V supply.

Wait at least 30 sec after anything you have connected to the 12V supply goes off.

Turn on the 12V supply.

Wait at least 2 mins.

Turn on the Flex.

Wait for all the startup screens and loading screens. Do NOT log in to the radio remotely, and do not touch the front screen on the Maestro until...

Wait at least 2 mins AFTER all the changes happen on the screen (so at least 2 mins after you get to the final screen before you chose to operate OR connect from a computer).

Connect with SmartSDR or click Operate on the Maestro and enjoy.

Slow procedure, I know, but it does seem to get rid of any of the cutouts or ticking on my end. I think the most important "pause" is actually waiting for the radio to "settle" AFTER you power it on, but before you connect or operate from the Maestro front panel.
