Hello,
I am experiencing an issue that I cannot use my full analog vtx capabilities. I wasn’t able to set the 2.5W transmitting power, the power levels were locked at 25mW or 250mW. After setting output to higher level the vtx power on OSD just started flashing.
Also I wasn’t able to change vtx channels with ELRS lua script.
I was using IRC tramp.
The setup is TBS Lucid H7 and GepRC Maten 2.5W.
Maybe anyone had any success here and could help me?
can you share you .param file
also refer this Video Transmitter Support — Copter documentation
i am using hglrc zeus 800mw vtx with IRC Tramp and it is working fine upto 800mw and i can adjust band, power, channel, etc easily using params of the vtx and pit mode works too.
Yes I can share the file with you.
I was following the copter documentation for the full setup, but I still was only able to change channels through the GCS not the Lua script in my radio 
Thanks for help

You need to modify the ardupilot firmware to increase the power level beyond 1000mW, ardupilot is currently not configured to be able to send a command for a higher power to the VTX.
You actually need a slightly more sophisticated solution for Tramp - AP_VideoTX: surface actual transmit power and bound Tramp retries by andyp1per · Pull Request #32937 · ArduPilot/ardupilot · GitHub
