This may be of interest to radio amateurs wanting to run LoRa on 2m

The now defunct SWARM satellite system used Modems (called M138) which would probably make good 2m Lora Transceivers without modification.

The SWAM service is now defunct - so these modules should be coming onto the surplus market.

The M138 modules were designed for 137-138 MHz (downlink) 148-150 MHz (uplink)

Onboard the M138 is LoRa, GPS (uBlox), processor and flash:

u-blox EVA-M8M-0-10 (bottom far right)

STM32L562CEU6 (bottom left of center)

IS25LP064A-JKLE 8MB flash (bottom, just left of center)

Sx1262 (left top)

There is also a RF amplifier (top right) 2x2mm, 12pin QFP package - possibly Qorvo TQP3M9008 - marking J2 and 2121 (date code?)
