Thetis 2.10.3.5, 16-bit Hermes Protocol 2 no TX signal

Postby afilip » Fri Mar 21, 2025 2:11 am

Recently I installed the latest Protocol 2 firmware on my TAPR Hermes.
The receiver works fine. For some reason Hermes is not generating TX signal while Tune or CW key is hit.
This was not happening while Hermes was running the latest Protocol 1.
I believe this issue was already explained by Scott on this forum but I can't find it.
Any help would be appreciated.

This morning I turned on Hermes running Protocol2 and Thetis and to my nice surprise transmit signal appeared.
I don't know why the radio was transmitting yesterday despite turning it on/off couple times after Protocol 2 firmware download.

I'm adding another post which may be useful for those who experience this problem. The difference between first day tests after Protocol 2 download versus the second day was PC status. On the second day my PC was tuned on after being shut down at the and of first day.
So it look to me that after Protocol 2 download to Hermes, PC running Thetis must be rebooted Hermes to resume transmit.
