Negentropy syncing notes over meshtastic links would be cypherpunk af. fully distributed, p2p, signed application data over radio. Who needs ISPs? They are a chokepoint anyways. So many cool usecases to explore outside of microblogging.
Imagine a lora setup for a local community, syncing notes between each other without any real internet infrastructure in place.
To send a note would be simply writing it to your local database. When nodes are online at the same time they simply sync with each other or a local relay server.
You could totally build distributed, low connectivity, store and forward applications this way if nostr was used for your application data.

Ham Radio License Test Preparation:
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.

DYK: The Solar Cycle (☀️🚴♂️) has a huge impact on HF radio propagation. This cycle is looking to be one of best cycles for propagation in decades and we are going to soon be entering the peak of the cycle. If you were on the fence about getting your ham radio license or upgrading your license to do HF, perhaps this will provide you some FOMO to get on it now.
Digging Deeper: The solar cycle is an approximately 11-year cycle in which the Sun's magnetic activity fluctuates, causing variations in solar phenomena like sunspots, solar flares, and coronal mass ejections (CMEs). During the solar maximum, the Sun is most active, with a higher number of sunspots and solar flares. In contrast, the solar minimum features fewer sunspots and reduced solar activity.
The impact on radio communications, especially in the high-frequency (HF) range (3 to 30 MHz), is significant. During the solar maximum, increased solar activity enhances the ionosphere's ability to reflect HF radio waves, improving long-distance communication. However, solar flares and CMEs can cause sudden ionospheric disturbances, leading to radio blackouts and disruptions in navigation and communication systems. Conversely, during the solar minimum, while there are fewer disruptions, the ionosphere's reduced ionization can limit long-distance HF radio propagation.

Earth-Moon-Earth (EME) Radio aka Moonbounce is Inspiring Electronic Musicians to Create New Music Delay Effects.
Radio signals can be bounced off of the surface of the moon in a process called “moonbounce”. This technique has been in use since the WWII and is still practiced today by radio amateurs. Although radio waves move at the speed of light, the moon is far enough away that there is a delay for the radio signal to get to the moon and return back to earth. There are other properties of the moon surface and radio waves that also impact the signal on the received end. This effect is now being used to create new musical delay effects such as the one in this video, “Echos from the Moon”.
On a moonbounce radio & bitcoin tangent:
"...I believe every nation should commit itself to achieving the goal, before this decade is out, of bouncing a bitcoin transaction off the Moon and returning it safely to the mempools of Earth.” ~made up historic quote circa 2024

Ham Radio Crash Course (aka HRCC) takes a look at latest software releases on various meshtastic devices. The new t-deck ui is coming along and will be a significant advancement. There was also a segment about a new version of the firmware that was made special for events with large numbers of mesh devices such as Def Con.

During the intro segment, NVK calls on bitcoiners to go out and get a ham radio license. In the main segment, they cover the new releases for Reticulum and RNS. They cover the open source M17 Project digital radio mode release updates and they close on wanting to do a full panel with ham radio bitcoiners and lament the lack of ham radio nerds in bitcoin.
NVK summed up the radio topics with “radio is magic”. 📻⚡️=🧙♂️

Yes, you could do it cheaper.
Thanks. In time, I think the word will get out that radio is a decentralized freedom technology & that bitcoiners and nostriches will greatly benefit from mastering the rf domain. Either way, I enjoy doing this and appreciate all of the folks who are already here.

⚡️ 🚙 📡 Radio direction finding made very easy for less than $1000 in fiat.📡🚙⚡️
Check this out and think about what is currently possible with low cost civilian radio direction finding. This technology will only get cheaper and more features over time.
Definitely check out KrankenRF’s github too. Link in thread.
DYK: In ham radio, there is a sub-community or sub-hobby within the hobby interested in rf direction finding. These folks put on “fox hunting” events where teams compete to find a hidden transmitter (aka “the fox” 🦊 ). Even with technology like this, it may not be as easy as you think because of other factors that can come into play that you will learn about as you go further down the radio rabbit hole. 🐇🕳️

This is a great DIY project for cypherpunks. It is also a great project for using a cheap SDR.
It can also be a great way to introduce pre-coiners in your local ham radio club to bitcoin and why bitcoin nodes are important. There are a lot of very smart people in your local ham radio club that we can bring in to our side.
1. ⚡️⚡️ Satellite Transmission: Transmits Bitcoin data, reducing reliance on internet connections.
2. ⚡️⚡️ Global Access: Provides Bitcoin data access in regions with limited internet.
3. ⚡️⚡️ Network Resilience: Increases resistance to internet disruptions.
4. ⚡️⚡️ Privacy Benefits: By not relying on local ISPs, which might monitor internet traffic, satellite nodes enhance privacy and reduce surveillance risks.
5. ⚡️⚡️ Equipment Needed: Requires a satellite dish, USB satellite receiver, and a computer.
6. ⚡️⚡️ Lower Costs: Reduces bandwidth costs in areas with expensive internet.
This system promotes Bitcoin network decentralization and ensures privacy by enabling access and participation without traditional internet dependency.

For around $30 fiat, you can get a SDR, an extremely powerful radio that you can use with your computer and FOSS applications. You don’t need a ham radio license to buy one and start playing with it.
There has never been a better time to start learning about radio.
Q: What is SDR?
A: Software-Defined Radio
