Hey all, new flyer here hoping for some help.

I have a Mobula 8 with HdZero Box Pro and a Radiomaster TX15.

I've been having a persistent issue when flying that it only transmits from the VTX at 20Mw and digital feed becomes static at around 25m when my understanding is it should be much much farther. I've tried a few fixes only including in my LuA Script and forcing power level 2 (did nothing) and ensuring properly set up on SpeedyBee. Not really sure what I'm missing.

Hopefully I've provided enough info and I'm missing something simply (I have thick skin). Attached are screenshots showing my R : 1 : 20 and my SpeedyBee settings, not sure if that's even helpful.

Thanks I'm advance for any help on this, not sure where else to turn to.
