Remote operation with FT-847

Well, not bad. I put an ethernet cable around the study reaching out to the radio, plonked a cheap USB sound card and the Pi, with my old USB to Serial adapter into it and voila, it works with VNC quite well, CAT and the lot. There are future experiments to be made, like using something faster than VNC but it works, apart from 6m.  At 6m the cables are getting interference and the TX'ed signal is horrible. Needs more investigation.  Other thing to look into is the audio cables, right now they are electrically connected.

Overall I spent way too much money on this antenna compared to something off the shelf like a number of Am-Pro sticks could have been bought but that's not the fun (or frustration) part of it. I have had some MTB wheels in the garage for years, collected from bikes that have gone to the Rust section of the Silicon Heaven.  So finally this Saturday I got off the couch and wandered down to the garage. After checking out the two front and two back spares, I picked the one that's in worst shape, a front wheel with scored rims which came out of an old Raleigh bike i had picked up from Freecycle which was beyond any meaningful repair. The rim was in a relatively good rust-free shape and t...

M0!

 Finally obtained my full UK license - it's an M0. Unfortunately I had to surrender the M1 but I guess I could have insisted on doing it on paper and re-obtain that, I've been using it for a long time now, but hey, I like my new callsign. All I have to do now is remember how to say it.
