I finally received my SX1262 from Waveshare and was able to build a Meshtastic image on a 32GB SD card, on an 8GB Pi5 (on my dev workbench). This image is based on the current version (as of 11/01/24) of Bookworm (with the Labwc Wayfire compositor selected). I have since copied this image to a 1TB NVMe drive - it's a "brisk" little Pi to say the least.
Works like a champ! Plus I was able to establish comms on channel 0 with my NOMAD device. I was a bit concerned about my NOMAD's radio. Since upon unpacking and in my excitement, I switch NOMAD on for a few seconds w/o the antenna attached. :-o
GUYS you really need to attach an easy to remove sticker on the front of NOMAD prior to shipment; warning to *NOT* switch on before attaching the antenna.
One thing I noticed, although every message sent was received by the opposite radio. Sometimes the msg header in the senders Web UI was never marked with a "Check Mark". Which I presume is meant to be an acknowledgement of receipt by another radio? Or perhaps I am assuming incorrectly about this?
Thanks!

You are right about that sticker - we need to add it.
Found an old, "official" 7" touchscreen I had around. So, I grabbed a 22 to 15 pin DSI display flex cable and cleaned up my bench LoRa "base unit".
Nice! That's a neat setup.
Thanks!
Adding a Nooelec NESDR Mini, a decent antenna, some RG-58 coax. Might make a marketable Spec5 base station?
Something like that is on the roadmap... and it will have some fun twists. When its closer to being materialized, we'll share and get your feedback, as well as of any other interested community members.
After a bit of thought/experience. I don't think a SX1262 needs to be in the Bench Unit. Even low loss LMR cable will cost you 2-3 db in a 30-50 ft length. Maybe the better omni verticals can achieve 10 dbi. So 7-8 dbi ERP at best.
I think it would be better to put a nice SDR (maybe a FUNcube dongle?) in it for use with gqrx as a spectrum analyzer and then let it connect via WiFi to a small, wx tight repeater on the roof for mesh work. This way you'll get your full 10.1 dbi on the vertical.
Just my two cents...
p.s.
I ordered my SDRPLay RSPdx yesterday. I've been bitten by THE BUG! :-)
The base station system will have an SDR for sure; though it may be an option since some folks might want to save the extra cost.
