"This website is dedicated to interesting and unusual electronics engineering projects in the field of radio receivers, transmitters, television and general electronics." Undersells itself quite a bit! There are some very detailed and well-written articles here about radio and TV restoration, and a few on test equiment and the Sol-20 computer.

uBITX -A compact HF transceiver edit / delete
Applying the BITX philosophy (good performance out of absurdly cheap parts) to a multiband SSB radio. The trick here is using an Si oscillator chip that can provide three separate outputs -- so you can do things like switching sidebands by tweaking one oscillator either side of the final filter frequency. Very neat!

From the Trenches | Ideas | CBC Radio edit / delete
"PhD students spend years hunting for answers to the world's unanswered questions. They usually toil away in obscurity.... until now! Producers Tom Howell and Nicola Luksic shine a light on these emerging thinkers and their work." What a great idea for a radio programme!
ZR6AIC: Creating a 2m Fm Repeater with a Raspberry Pi (B) and a RTL dongle. edit / delete
As it says. They have a hat board with a 2m filter on; it could really use an amplifier too, I suspect.
