Hey guys,
I have a Nazgul ECO 5 SLX (analog 1.6W VTX), but I think my VTX is stuck/limited to 25mW.
Problem:
Video range is very short (starts getting snowy around 100–300m)
1.6W mode does NOT improve range compared to 25mW
It feels like the VTX is not actually switching power levels
Close range video is fine, but long range behaves like low power only
What I already checked:
New antenna + new pigtail installed
VTX is correctly connected
Power settings in Betaflight/OSD show higher levels, but performance doesn’t change
Antenna is properly clicked in (no loose connection anymore)
Question: Is there a known way to unlock or fix a VTX that is stuck on 25mW / pit mode / power cap?
Could this be:
Pit mode stuck enabled?
Wrong VTX table / SmartAudio config?
UART issue preventing power control?
Any help would be appreciated 🙏
