Did some cleanup on the web page today.

There actually is a global public network. I host a #public #reticulum node that you can connect to over the commercial internet: https://reticulum.n7ekb.net. It provides a bridge from my local low power RF-based (#LoRA) nodes to other RF-based networks. I also run a mobile RNode in my car that can use my mobile phone to tie it into the "global" network.
I just posted about this early today:
#reticulum #nostr #development
Here's one for #asknostr: Filed in https://github.com/greenart7c3/Citrine/issues/61.
I run #Citrine on my phone (Thank-you!!!) and also run a personal nostr relay (strfry) on my VPS so that I have two locations for all my notes. These are entirely dependent on the commercial internet however. I also run a program called #Sideband which connects to the #Reticulum network using a locally hosted transport router for Reticulum. How feasible/difficult would it be to add support in Citrine to publish/interact with my local Reticulum transport? The Reticulum transport has a lot of options: Reticulum Interfaces. Such a feature would make nostr over Reticulum possible in areas where commercial internet is unavailable (#disaster/#censorship).
I've migrated from #Anytone to #Tytera. I use the MD9600 (a dual band analog/DMR base mobile radio at $220) and the Tytera UV-390 (also dual band analog/DMR at $120) as my handheld. Both radios came shipped with the #OpenGD77 firmware. This common firmware means I use the same #codeplug for all my radios, and the #DMR programming is #ham friendly with the OpenGD77 approach. These radios support #hamradio as well as commercial, so they meet my needs in the #EMCOMM space really well. (Our town's EOC uses DMR). I've found the UV-390 to be more rugged than the Anytone handhelds for daily carry, especially outside in rainy weather.
It's fun indeed! Most #meshtastic devices are easily converted to #RNodes for use in a #reticulum environment as well. Double the fun! https://reticulum.n7ekb.net

A lot of #hams ignore the other radio services which are often better suited for meeting the needs in some parts of a #disaster plan. You're wise in connecting the dots between the experimenting nature of #hamradio and the use of the knowledge gained there to solve real world problems with ALL the tools available.
Finally got around to troubleshooting my #NIP-05 setup after the move to a new #Debian #Linux server. In the process I used #Grok to research the needed Apache configuration to allow #nostr client access to the /.well-known/nostr.json file.
Grok did great on the basic research query! But on my subsequent bunny trail queries it determined that I'm the ONLY #hamradio operator known to the interwebs that hosts a nostr relay!
#CQ, CQ all #hams! Tell Grok you use nostr and that you host a relay! 🤪
On #linux you can specify a /dev/serial/by-id that is persistent across reboots. That's unfortunately not a native option in #MacOS. It might be possible to mimic the linux behaviour with a custom Python script using the pyserial library to enumerate the serial ports and create /dev/serial/by-id links for you.
This looks like it be a great platform to run Liam Cottle's #reticulum #MeshChat!

Are you referring to reticulum.n7ekb.net:48086? It doesn't appear to have any issues on this end.

I actually read just the opposite from someone who posted about their test results. Higher SWR with the 90 degree angle versus straight. Antennas, feedlines, and RF are so fickle.
Is anyone working on enabling the #Meshtastic UI to operate over a #Reticulum network?

Try Liam Cottles' #Reticulum MeshChat app. You can send audio snippets over #reticulum links.
#Reticulum would be a better suited protocol for this application.
Ugh. Why not build this as a software layer on top of the existing RNode devices? Yet another firmware that's incompatible with any other existing mesh... 😢
The #Reticulum Network World #Map Project went live today:
I'd like to see some #EMCOMM minded #hamradio sites show up on this map. In theory #EOC client computers running reticulum-meshchat day-to-day would have transparent fallback to RF-based connectivity when their commercial TCP network goes away in a #disaster event.
Has anyone investigated the possibility of building a LoRa-like low-power transceiver for 49.82-49.90 MHz band for use as an #RNode? This might have greater range in rural, tree-covered areas that limit 800/900 MHz signal propagation.

( Quoting from the https://www.hfunderground.com/wiki/index.php/Part_15 )
The 49.82 MHz to 49.90 MHz band allows for personal hobby transmitters up to 100mw output with any modulation as long as the modulation stays within the 49.82-49.9 MHz band. This provision within Part 15 opens up opportunities for 49 MHz beacons, provided an effective antenna is used.
§ 15.235 Operation within the band 49.82–49.90 MHz. (a) The field strength of any emission within this band shall not exceed 10,000 microvolts/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. (b) The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodulated carrier or to the general limits in §15.209, whichever permits the higher emission levels. The field strength of any emissions removed by more than 10 kHz from the band edges shall not exceed the general radiated emission limits in §15.209. All signals exceeding 20 microvolts/meter at 3 meters shall be reported in the application for certification. (c) For a home-built intentional radiator, as defined in §15.23(a), operating within the band 49.82–49.90 MHz, the following standards may be employed: (1) The RF carrier and modulation products shall be maintained within the band 49.82–49.90 MHz. (2) The total input power to the device measured at the battery or the power line terminals shall not exceed 100 milliwatts under any condition of modulation. (3) The antenna shall be a single element, one meter or less in length, permanently mounted on the enclosure containing the device. (4) Emissions outside of this band shall be attenuated at least 20 dB below the level of the unmodulated carrier. (5) The regulations contained in §15.23 of this part apply to intentional radiators constructed under the provisions of this paragraph. (d) Cordless telephones are not permitted to operate under the provisions of this section.
