Radio is fascinating. Check this out.
GMRS can be a gateway to ham radio. People like it because there is no test to get licensed and one license is good for the whole family, including for the children.
This video covers some basics on using GMRS repeaters.

Ham Radio Pep Talk: Ham Radio is Not Hard
Some information about encryption on meshtastic:
Perhaps we can get some of our eyes on this too for the meshtastic project.

This is a very cool demonstration:
RF can be very dangerous, don’t try this at home kids.
nostr:npub1ya20ep3dd0qt0suhzprxztv5y43arqwps73ercvqa44sp7qw0edsp4x9ty could you make an HF array antenna from domestic house yagi antennas? They’re only directional at VHF etc, at spacing of 20-50 m the way they’re wired into suburban houses all I see is a potential to have a distributed OTH tx/rx.
Obvs requires precision timing coordination between nodes in each home. I think it would be only modest power draw for each tx element…
Just a thought.
I hadn’t thought of this before, let me know how it goes if you try it.
For new hams.

I think there will be a lot of demand for this in the coming months as the word gets out about #Lora & #meshtastic.
There are already folks coding & doing cashu over these meshtastic devices.
These mesh devices should be able to pass messages via mesh for the coming coinkite satslink.
This will be big.

This is not a prank or an April Fools’ joke, during favorable conditions in the solar cycle, you can use a wet noodle as a radio antenna.

OH8STN on YouTube is a great channel for digital ham stuff.
1. Use HamStudy.org: HamStudy is a free website that provides practice tests for all ham radio licenses. It can help individuals prepare for their exams and find online or in-person test sessions. www.hamstudy.org
2. Check Out W4EEY on YouTube: W4EEY on YouTube offers excellent ham radio tutorials. He has playlists covering all ham radio license levels and occasionally conducts live classes. This resource can be valuable for learning ham radio concepts. Here are the playlists for the various licenses:
• Tech Playlist: https://youtube.com/playlist?list=PLZ_9BZQ8gpziUWPBT3rOvSV6MCCeCaiK0
• General Playlist: https://youtube.com/playlist?list=PLZ_9BZQ8gpziv2a26B_IoQ1RbXbIqieP2
• Extra Playlist: https://youtube.com/playlist?list=PLZ_9BZQ8gpzh7NC1WVKwCCmOTULSj1f93
3. Explore ARRL and Local Clubs: The American Radio Relay League (ARRL) website can help individuals find local ham radio clubs. These clubs often have information about local repeaters, club meetings, and ham radio "nets" (radio meetups). It's a good way to connect with other ham radio enthusiasts in your area.

Let’s get some eyeballs on this GitHub: BTC Mesh Demo
“The purpose of this repo is to demo a library that transmits bitcoin objects (addresses, raw_trx, psbt, etc) over a mesh network.
This project leverages:
The bdk-python bindings for Bitcoin wallet and transaction functionalities. More information can be found here: bdk-python.
The Meshtastic Python API for transmitting data over mesh networks. Documentation and details are available at Meshtastic Python API.
Setup
This example assumes there are three meshtastic devices (Alice, Bob and Charlie) sending around PSBTs. I used two different LILYGO T-Beams and a T-echo. You can adapt the demo to work with fewer or more devices as needed.”
