Building a LoRa APRS 439Mhz iGate (Part 4)

…not just who’s been heard by your iGate, but which packets have been relayed, which came direct, and how many got garbled along the way.

Sometimes you might even notice familiar folk passing by. :wink:

Hello

All is okay with me, I was camped on Seatallan (G/LD-025) last night. Was very stormy, with wind reaching almost 40mph in the early evening, so quite a rought start to the night. Th eweather soon settled down though, and it was a glorious morning today.

I was also camped on the same summit on Friday night a week ago - when we had 48 hours of almost constant rain. It was very wet!

And a couple of weeks before then, I was on the summit to rescue my LoRa beacon, M0MZB-15. That night, it was a bit too windy for a summit camp, with wind in excess of 40mph, so I camped at the nearby Greendale Tarn. The Beacon went off the air a few days prior, and I discovered that the had cracked around the antenna socket, and the antenna fallen over. It looked like it had taken some rough handling, perhaps from a sheep. The box had filled with water, and the beacon died. I recovered all the parts and have returned them home with me.

The beacon lasted almost exactly a year, requiring only one minor repair during that time. It stayed on the air for all except a couple of gloomy days in October 2024.

I’ve no plans to re-instate it yet…currently working on some other projects.

Hi all, I’m late to the game with LoRa APRS, but amazed by the achievements of the group with these tiny devices! This could actually get me out and up of our wonderful South Wales hills when it gets a bit warmer!

I have a couple of LilyGO T-Beam units - one used as a tracker and the other an iGate - they work very well with CA2RXU’s excellent firmware. I’m based in Cardiff - not much atvitity here at the moment, apart from me taking it everywhere to test while the novelty lasts!

I also have a “Waveshare SX1268 433M LoRa HAT” (yet another Pi Hat!) and was thinking about this with a Pi 4 etc for use as a iGate. This does not appear to be supported by Richard’s firmware, so my question is whether anyone here has any experience with this unit, or know of any iGate firmware that could be used with it?

Many thanks and 73,

Steve MW0KST

Interesting stuff this LoRa APRS. Having set up an Igate/digipeater covering G/ SE001, I have been fiddling about with the tracker and found you can send them messages. May not be news to some but amazed me. Now in the tracker menu’s there is also an option to write a message but needs a keyboard. Could be an interesting option a message could be sent from the tracker. Anyone know?

Burrow back in the companion threads about the LoRa Tracker, and you’ll find posts about hooking the tracker to a phone via some variant of bluetooth (typically BLE if my memory’s not too flakey) and using the phone as a keyboard. For some, it worked, for others, not so much…

Thats very interesting, I did wonder as there is a Blue Tooth feature. I will have a dig back and play about with it.
