Wouldn’t this be better served on the WSJT-X group, Amos??  This group is for HamApps.


Just sayin’….

Thank you for your comments.

I am not familiar with the internals of WSJT-X and JTAlert. Please explain the role of Hamlib.

I did create 6 instances of WSJT-X only 4 working concurrently. Lately I did create 7th and 8th instances but they did not work. Any explanation?

How many concurrent WSJT-X instances are you able to use?

I am facing the same problem as Frank, I2DMI, which is important because of its interaction with my StepIR antenna which is dangerous to the power amplifier.

In addition,  starting Tx on two instances makes 6600/SSDR Tx alternately on 2 slices.


Any thoughts will be welcome

Amos -

I didn't write that WSJT-X  doesn't work with SSDR - I run two 6700s, one of which feeds eight instances of WSJT-X and JTA. What I did write is that Hamlib doesn't fully support SSDR - it only supports "VFO A" and "VFO B" - it has no concept of switching between SSDR panadapters and/or slices, so it can't designate a specific slice for transmitting without resorting to COM port emulation for each slice. This was a bigger issue before SSDR and SmartCAR implemented 'Auto TX Switiching' but still causes some operational issues (as you noted) and I'm corresponding with the developers about how to implement a complete solution.

And, as I said, this should be moved to WSJT-X list.
