RAK Wireless RAK6421 with RAK1330x

Im having issues with TX power on the above setup.
I notice the dev branch has these omitted.
Is there an issue or should be looking at my boards (which are brand new)?

These boards should work, but you need the dev branch. as the core LIB has changes for these boards

Excellent. I will pull the dev branch. And see if that improves TX. I could barely get 10m on main branch. Thanks

Yes without the update core lib it will not power up the PA.

Aah. That makes sense with low power. I will report back later when I get home. Thanks again

I've removed, pulled dev branch twice. Im thinking it must be the board as its showing noise floor and drawing roughly 200ma when transmitting just got near on zero signal strength but great quality. Shame as I got this board as my waveshare (i already had) wouldn't TX at all. (Know issue)
