I'm interested in all sorts of stuff....
Amateur Radio - CW and HF mostly, but I often take a detour into other areas of the hobby.
Calculators - as long as they use RPN
Music - I noodle on recorder, mandolin and guitar
Diary Keeping - I write a daily diary and include small sketches and other ephemera to illustrate my own life-story....
Chess - I'm a rank amateur playing only for fun and only against close friends
Anything geeky or nerdy.... gopher, *BSD & Linux....

G-QRP : 2377
SKCC: 3214

Carried away with the Selcall / Codan / Barrett mood from seeing @oe1lfb with his Codan, and dusting off my Selcall-capable Jenal SC2 mics I've made a rambling ramshackle (isn't everything I do rambling and ramshackle?) video on Peer Tube:

If anyone wants to experiment let me know. We can even cheat and use Allstar as an Engineers-Order-Wire (my node number is 481483) for co-ordination and chit-chat

Demo of CCIR493 HF Selcall

PeerTube

After my excitement last night that my AR7030 is still alive.

I have taken out the faulty tuning encoder to inspect it and find the internal pcb with the printed tracks is broken in two pieces.

Now is the time to replace it.

Has anybody got a definitive spec or part number for the original ALPS mechanical encoder - PRR etc. or a part number for a modern replacement. I can fit a Bourns optical encoder, but again, I'm not sure of which part would be correct.

Inspired by @oe1lfb posting a pic of a new Codan Envoy I was reminded of my previous experiments with CCIR493 HF selcall.

I haven't done anything with it for a few years but I have some old notes on my wiki

I've connected a Jenal sc2 mic to my G90 and its monitoring 14.342MHz with selcall id 3658 if anyone fancies doing some tests. The G90 will send revertives out (@ 20 w) for direct selcall, direct beacon call and "99" beacon call

Didn't take me long to realize that as a #morsecode fan I perhaps shouldn't follow the hashtag "cw" on Mastodon....

content-warning != morsecode

Thanks to Christopher @M0YNG for re-activating my old and dormant account, which I first set up in 2022.

He suggests an #introduction post, so here goes...

I'm up in #shetland and have been resurrecting my #amateurradio interest recently, so I thought it was an ideal time to re-connect to the world via Mastodon, too.

I've also started a #peertube account with #makertube to put up the occasional radio-related video.

Cheers & 73,
John
