Hello!
I recently received a pre assembled unit from the web store (new diy tech). I am seeing ~.5w output via 5v usb on 40m upper side band. Tried running a battery today, unit shows 13.0v on transmit at ~1.8w. Is this normal?

1.8W is not normal.
Check Board setting, if you've bought Classic and it's set to Lo or Hi bands then this might be the case.

The website I purchased from [newdiytech](https://newdiytech.com/products/trusdx- ... and-dl2man) says they are selling the `[LO]` version. My board says 1.0. In the menu 8.7 is set to `LO`

Hello OM,
please measure with a power meter or with an oscilloscope at a dummyload, maybe there is something with the power measurement.
I can conclude this because you measured 0.5W @ 5V so you should get 2W @ 10V and 3.3W at 13V....
