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

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
