Can't help with RadioHead library sorry, but if you haven't seen them already
Microchip has LoRaWAN modules that incorporate a PIC18LF46K22, SX1276 radio
chip, crystals, EEPROM with ID, antenna matching networks etc. See the RN2483
(dual freq 433 &amp; 868MHz) and RN2903 (915MHz). Cost is not too high, probably not
much more than what you can buy the individual components for, and it's in a nice
small metal shielded module.

You can re-flash the firmware on these to run anything you like (ICSP I/O pins come
out on external pads), but they come with a pre-qualified LoRaWAN application
which could well be suitable out of the box. The source code is also published, so it
could be alternate pathway for you.

The Radio Head library can be made to work with that model PIC - I did it for a specialized application. Unfortunately the work I did cannot be easily shared and I'm over committed at the moment.

I use the CCS C compiler - PICC  which is a little different than the Microchip one.
I think there is a version of the RadioHead source on the HopeRf site.
