Hey #nostr #Hams! Amateur Radio Newsline is available on Fountain.fm with streaming SATs enabled! Its the first #amateurradio podcast that I've seen that's supporting value-4-value.

Added this #BitAxe to the #Hamshack today. It's solo-mining (also known as the "Bitcoin Lottery"). It's a lot quieter than I anticipated. Now it just needs to hit the lottery to help pay for some new #hamradio projects! 😀

Just getting started with "block 44" in the #hamshack. Are there any other #nostr #hams using a #block44 address?

My #hamradio/#technology web site is still hosted on my VPS with an ordinary IP address, but is now also reachable at www.n7ekb.ampr.org .

I honestly don't know what the rules are for this ham in the Netherlands, but if I was to implement his design here in the US, I'd put the nodes on a commercial band frequency to avoid the encryption mess under Part 97 rules. For #EMCOMM I've been toying with the idea of using one of our town's dedicated public safety frequencies for a UHF band LoRA #reticulum #RNode network. #hamradio is too restrictive with the required individual licensing and rules regarding encryption, etc. For example, in a #disaster we can hand out radios from our town's radio cache to non-technical volunteers who otherwise meet volunteer requirements (background check, etc.), and not worry about a ham license.

A 2 watt RNode design. #reticulum #PE1RXF #nomadnet #hamradio #meshtastic #homebrew #esp32

https://www.meezenest.nl/mees/projects/reticulum_design_my_own_rnode/index.html

Looking at the below abstract from the #Reticulum manual brings the following ideas/questions to mind: How hard would it be to modify a #nostr relay to allow connections to/from a #Reticulum network? Along the same lines, how hard would it be to modify a #nostr client to utilize a #Reticulum network as a transport?

#asknostr #strfry #nostrrelay #nostrclient #meshnetwork

Pipe Interface

Using this interface, Reticulum can use any program as an interface via stdin and stdout. This can be used to easily create virtual interfaces, or to interface with custom hardware or other systems.

``````

`[[Pipe Interface]]

type = PipeInterface

enabled = yes

# External command to execute

command = netcat -l 5757

# Optional respawn delay, in seconds

respawn_delay = 5

`

I don't quite understand this article. I just finished setting up my own #XMPP / #Jabber messaging server on https://xmpp.n7ekb.net. I don't get the connection between a phone plan and XMPP. Especially the comment "privacy-enhancing phone service using XMPP".

#asknostr

I payed for the life membership when I first got my #amateur #radio license. I had too much money burning a hole in my pocket, and frankly didn't know any better. I'm still waiting on #ARRL to issue my #DXCC which was electronically confirmed within seconds after my 100th validated QSO in #LoTW. For an organization supposedly representing amateurs who 'contribute to the advancement of the radio art' they're woefully behind in technology. It's sad... 😢

The installation of my self-hosted Jabber/XMPP modern messaging server on #Debian is done. For the second time. That's right. I had it all up and running on a shiny new VPS a few weeks ago. I had the new installation passing with 100% compliance on https://compliance.conversations.im/server/n7ekb.net/. Then I *deleted* it instead of the old #Rocky #Linux VPS I had on the same hosting service...

Of course I made this swift rookie mistake *before* I'd setup my offsite backup!

Soooo. Guess what? The new re-installation is now backed up three ways to Sunday. My old friends git and rsync are happily guarding the server from this incompetent server admins!

Setup for family and friends and #hamradio, https://xmpp.n7ekb.net is ready for action.

So you configure your radios to talk into the repeater on one time slot and then listen on the other timeslot?

#dmr #hamradio

I just turned the example whitelist into a blacklist today! I also made some minor tweaks to print an "ACCEPTED" or "REJECTED" line along with the public key hash to the log file. Now I can grep through the logs and see who's being naughty or nice... A simple grep | cut | sort makes a list where large blocks of the same ID are easy to eyeball.

#bash #grep #nostr #spam

My self-hosted #Nostr #Relay logs were growing, growING, GROWING!

So I set out yesterday to determine exactly what was going on.

Guess what I found?!? A handful of clients from different IP addresses were causing a continuous stream of error messages where the relay was complaining of a "filter item too small".

So I tweaked the logging settings to get dumps of the requests generating the errors.

Each error entry looked like the following:

2025-05-02 13:12:41.038 ( 198.848s) [Ingester 0 ]INFO| sending error to [21]: bad req: filter item too small

The culprits were trying to request a list of articles with an author list that basically covers every possible Nostr ID... Or something along those lines.

If you're using a nostr relay you aren't paying for, remember to #zap your relay operator. They deserve a little love from time to time!

#sysadmin #admin #linux #cybersecurity

#nostr is not just #bitcoin

About the net:

The PNW Digital ARES & EMCOMM Check-In Net is held

every Sunday evening at 7:30 PM local time on PNW

Regional, DMR talkgroup 31771. DMR Talk Group 31771 is

available on both the PNW Digital and the Brandmeister

DMR networks. Anyone interested in Amateur Radio and

Emergency Communications is welcome to check-in. The

net is an opportunity for DMR-capable ARES and EmComm

hams to exercise their DMR equipment in a regional,

directed net. The net demonstrates the wide coverage

area and capability of DMR repeaters and hot spots in

our Pacific Northwest region. It also highlights the

wide range of EmComm-related organizations who have

members with DMR capability.

#net-reports #hamradio #EmComm #ARES #DMR #PNWDigital

Updated the python net report script to generate a better formatted report. Next optimization would be to publish the #nostr note directly from the script.

This still needs some work, but it's a lot better than the #RSS feed version turned out.
