ooh. That is great advice! We used the RadioHead mesh solution but it is super non optimal for us and we plan to switch. I'll definitely do some reading on DASH7.

Oh yes, totally agree. We have a rough duty cycle spreadsheet now and we will be careful to obey the rules ;-)

There are already a couple of companies doing similar kickstarters I think. But we want this to be a non profit open source project for fun. We are using a GPL license, but if someone wants to eventually sell devices (as long as they obey

Oh yes, line of sight makes a big difference (also working as mesh helps for forwarding packets). Also we use a very high spreading factor so the bit rate becomes super low (with lots of chirps)

encryption is allowed for low duty cycle digital usage on that band. I'm also a ham and really into APRS. But not requiring a license is a big plus, also the way these chirping radios achieve their long range with a super high noise f

Thanks! alas, I think that is a bit to big for what we have to work with in our ESP32s. We started our sw design based on what off the shelf hardware we could find and worked from that.

yes, that's what we thought also. Also, the phone is optional for our case (though you need it for sending texts - if you don't have one the display still shows rxed texts and headings/distance to members of the channel)

Hi ya'll, so we've spent a few weeks making device software and an android app to convert a $30 chinese gps/radio into a long range mesh radio for hikers. It is working fairly well now (though still an alpha) and we'd l

We're making an open-source $30 GPS/mesh radio, would like advice(meshtastic.org)
