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 ...

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.

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 ...

Richard,
this could be the same issue as with my Hermes/Thetis.
If Thetis was turned on while 20m was previously selected before turning power off click 30m pb and then click 20m pb again.
It works for me, I consider that as minor issue.

I deleted the wdspWisdom00 file and re-installed Thetis. It did not help. SSB filters were still ringing.
So the last resort was clean Windows 10 install, however all important data, passwords etc. had to be saved.
After clean Windows installation I've installed Thetis and tried it with Hermes. This ...

I've installed Thetis v2.9.0.6 on my laptop. That was fresh install, FFT bins had to be created.
Started listening SSB on 40m and... no SSB filters ringing.
This test proved that my PC somehow influence Thetis.
I re-installed Thetis few times on my PC but it did not help.
To do fresh install I will ...

Scott,
I'm not using VAC for audio.
My headphones are plugged in directly to Hermes headphone connector.
Is it possible that Thetis filters ringing problem is caused by PowerSDR still installed on my PC?
By the way I've been using PowerSDR mRX PS v.3.4.9.

I got back to SSB listening during last WPX Contest. It turned out that filters 2.1kHz and wider are ringing very strong making SSB signals impossible to copy. Only 1.8kHz filter is free of artifacts however it's too narrow making signal copying difficult.
It doesn't matter I use TAPR Hermes or 14 ...

Scott,
thanks for your prompt replay.
I've downloaded firmware ver.1.5 to 14-bit Hermes and the board is up and running again.
After using old Hermes board purchased from TAPR in 2012 my mind was stuck with that version of Hermes. I haven't realized that other version of Hermes was built.
I made ...

I received HPSDR 14-Bit Hermes board. It came with firmware ver. 1.5.
Using boot loader I setup IP address, no problem here.
Thetis 2.9.0.6 recognized the board, however while antenna connected to RX port no signal was displayed on spectrum.
Tried PowerSDR mRX PS ver. 3.4.9 with the same result ...

Scott,
I was running Thetis v2.9.0x64.
I've uninstalled that version, rebooted my PC and I installed v2.9.0.6.
Thetis 2.9.0.6 is working fine with split. I verified that checking spectrum and listening my CW signal on different receiver.
Thanks for your help.

Running Thetis under Windows 10.
For some reason Split is not working. I got embarrassed calling DX station working with split.
It turned out that I was calling him on his frequency despite selecting Split and setting VFO B 2 kHz above VFO A frequency.
VFO B turned red TX, TX CW frequency indicator ...
