Redoing this poll due to a suggestion by @kilroy_was_here ...

What name do you like best for a non-profit #FOSS community for Ham Radio? Think Apache incubator but for Ham plus other open-source services and resources for the community.

FYI I have both the dot com and dot org as well as the hyphenated and non hyphenated versions of the below. Please mention which variant you prefer in comments.

So I am starting a #FLOSS HAM community.. Think apache for Ham radio. The idea is to address the state of open source software and standards in HAM radio.

Anyone, particularly open-source devs have any interest in talking to me about this, even if its just to make sure their ideas are considered as I launch... but people who want to help more directly are welcome too.

So apparently I just realized when i first started as a ham over a decade ago I participated in an E-M-E contact (Earth-Moon-Earth). I had no idea what it was at the time but i see in my notes it just says "EME net?" and now as a more expiernced ham i literally know I was talking with someone by bouncing our signals off the moon..... soooo cool.

What do you hardcore #linux users use for #Ham radio logging?

Found a nice little group of guys, mostly in west virginia who apparently are on 3.803MHz every night 8 - 9pm... it is right in the sweet spot for my antenna (80 meters band i have a limited window where it tunes up very nicely). Happy I found the group so i have something to do. All really clear tonight, s9+10 so very promising. its about a 280 mile contact, which is pretty decent for 80m too.

Another amazing 10 meter contact... this time 5,300 miles to argentina over RTTY!

Just got my first 10 meter contact on the new antenna! 2,400 miles away in washington on 28.1MHz... 59 signal over RTTY.... very happy with this antenna so far

Weird, all the bands are open, but no one is on voice....

WOOOOOT! First contact on 80 meters on my new antenna. 3.892MHz, 290 miles (PA to west virginia).

The last antenna (same model and configuration) never worked on 80m because we never tuned the whip right... but this one everything was 59, excellent stuff!

Made my first contact on my new antenna... 15m band, 1400 miles (PA to Texas).

Cant wait until this evening to see how well it does on 80 meter!

The antenna is up, tuned, and working!

I'm trying to implement the complete v2.2 Ax.25 stack.. made a lot of progress but the more progress I make the more I realize this was a really poorly designed protocol.

If you do any sort of #Electronics work where you have to strip tiny wires of 20 AWG or less I highly recommend you get yourself a precision wire stripper.

My old antenna fell down after almost a decade. It performed so well i bought the same brand again and am putting another one back up today. Its quite tall (like 30 or 40 feet or sonething) and requires the whole roof to be covered in radials. This tine im coating the radials with tar to embed them into the roof itself. Quite the project but it will be worth it.

I am making tons of progress on my #OSS . #FOSS APRS project called #Digipex.

I got an igate relay hosted (this will be neccesary to ensure we can get dup packets):

https://igate.digipex.io

I got a web-app going that will display allt he clients on the map and give some statistics/status info:

https://hub.digipex.io

I also have the most important part, working code that talks to the radios and routes / rewrites packets. Right now it can send/receive, digipeat, and gate to and from the igate.

The code for digipex is here: https://git.qoto.org/digipex/digipex

And you can see some information about my particular digipex node here:

https://hub.digipex.io/views/overview.php?id=43449

The picture below is of a microcomputer (like a raspberry pi, its a khadas) running digipex and showing the packets it deals with on the miniature screen.
