Here are the toots from my Mastodon account. If you’re into ham radio and technology this is a great inclusive server with an awesome mascot called Alex.

It's Alex! A soft brown mastodon holding a handheld radio in their right hand and carrying a blue bag over their shoulder

Oooh: https://www.maplin.co.uk/ time to offload all the random junk I bought while they were closing down.

I always read “hihi” as some sort of maniacal fairytale giggle. Had no idea until today it was a morse thing!

Latest kit acquisition is a SMD Practice board. £1.72 from eBay and took about 3 weeks to ship. The board isn’t the best quality (and neither is my pic) but should still be fun to play. https://www.ebay.co.uk/itm/141890124297

Ordered a hupRF PAT board from https://www.sdr-kits.net/Panoramic-Adaptor-Tap-Boards then found out when it arrived that Jan G5BBL/PA5D the proprietor is local to me! Time I got around to visiting the local club I think.

Enjoying #introductions, so here’s mine:

I got my full license in July, having done my intermediate in Jan and Foundation in Dec, so I consider myself a newbie with an M0 license.

Got into radio to regain some knowledge in electronics (I have a degree in it, but don’t use it for work so have forgotten a LOT).

Loving it so far, especially construction and and messing with digital modes. Definitely still a bit mic shy but working on it!

Also, I 100% recommend the Bath based courses!

One of my staycation projects this year was the RSGB Centenary PSK Receiver.

I got the PCB from RSGB ( https://www.rsgbshop.org/cgi-bin/sh000044.pl?WD=psk&PN=Kits%2ehtml#a1385) and the bits I didn’t already have from Spectrum ( http://www.spectrumcomms.co.uk/), and then I bought an extruded aluminium enclosure from eBay to finish it off.

The build took about an hour in total and was all through-hole. The instructions also provide basic functionality tests which was a nice touch. Boxing it up took about another hour.

Not massively useful, but fun!

Built a Raspberry Pi Wobbulator and stuck it on top of an old Pi I wasn’t using (everyone has at least 2). It works and was fun to build! Got it via: http://asliceofraspberrypi.blogspot.com/2013/12/building-raspberry-pi-wobbulator-kit.html

Looking forward to building and measuring some home made filters with it once I’ve found some SMA cables.

The blue board on the right is a DDS module which it uses to generate a sweep of varying frequencies, then there are two inputs which measure voltage.

Back from a great weekend at Telford for the GQRP buildathon and convention, and hamfest. The convention talks were excellent and the live Soldersmoke episode was really well done. They put the last 15 mins in the latest episode (206).

Actually did finish it and it works! SWR, Lat and Lon(!), Maidenhead coordinates and more. Really fun evening.
