Its the built in standard. And recently was upgraded to be even more secure

This is awesome. I’m a big believer in stocking legacy tech because its cheap, readily available and usually can be repurposed for stuff like this. My only concern would be eating up a whole fancy SDR just for some more walkie talkies, but if you could find some dedicated 2G infrastructure radios on ebay or something I bet you could build a pretty cohesive system for a lot cheaper than other options. I personally always keep around a few dial-up modems still because I know that if a disaster ever strikes I can jack in anywhere where i can get a tone and dial up a telephone ISP to hopefully be able to access the internet

Basically meshtastic is a widely available system used to send location data and texts between a local network of devices. This allows for texting and location sharing between people within a group without reliance on infrastructure like cell towers or wifi, so basically you can text and see your friends on a map without service. It’s pretty widely available across a few different devices from different manufacturers and you basically just need the device, and a phone to connect it to in order to get up a running.

That would be a pretty cool experiment. HF is one I would love to get into but alas I too am at capacity for hobbies. I would also like to try to up the bandwidth on my network but I think my plan is to use traditional 5GHz internet radios to build an IP based network to hopefully not need to re-invent the wheel too much. We’ll both get there one of these days!

My recommendation is to get a couple lilygo T-Beams to start out experimenting. The Heltec radios are also pretty good but require a bit more DIY-ing to get them to the same level of functionality. The T-Beams are cheap, and include GPS, wifi and serial support all in a pretty good bundle. Pair with an old android phone and you’ll be rolling

Just spun up a community called comms. Hope to see you there friend!

Thanks dude. I appreciate the platform you’ve built here

I’ve begun to do very similar things. I’ve started to use a combination of different materials for sifferent components to maximize the functionality or aesthetic appeal of each part. Most often I’ve used either PLA+ or nylon for frames and large pieces and PETG-CF for small internals like mag releases. I think from what people have mentioned here I want to try out some PPA-CF next though
