Postcard (base, rover) with LoRa Serial kit setup help

[rftop]

You probably already read this thread, but Ryan M. (AORPLS) had the PostCard Base/Rover working over LoRa.

RTK and Lora

@sparky I switched to P2P mode, ran a airspeed of 9600 and got about 300 feet down the street and my base is in my backyard and I strapped the omni antenna to the tripod leg (literally so terrible LOS) so I ordered a pole clamp so I can get it up higher and away from the tripod. I was curious wouldn’t it be a benefit to switch the jumper to 5v to feed the LORA the lipo battery voltage and help the power levels just a little bit more?

Just in case you missed that thread when searching, but doubtful
