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.

Took two of these tiny diodes out of my Icom 706mkII to get access to 60m. It worked! Thought I had broken it, then I remembered to open the squelch and tweak the AMU. Nerve racking stuff! 😅🧐

I highly recommend signing up to Hot Iron magazine, at http://www.walfords.net/ordering.htm it’s free and full of info on homebrewed gear, tools and circuits. A bit like G-QRP’s SPRAT. That said, the last one was a 20 MB Word Doc 😂 (2 MB PDF)
