In this video I look at an old homebrew direct conversion receiver built when I was a nauseating adolescent and compare it with the last project we built here:

The old design is by Drew Diamond VK3XU and is published in a number of places including the G-QRP club book “Radio Projects for the Amateur” available to members only here:

If you are not a member of the G-QRP club, there’s really no excuse!

Lovely idea for a video, I too made Drew's designs in my callow youth. You missed an opportunity to turn them on and demo the differences, that would have made a nostalgic and educational video. Oh well...
BTW Drew is on 160m AM weekdays almost without fail in Melbourne, I listen in from time to time.

Interesting build. Your soldering wasn't bad. Next question, does it still work? 73 Clark KG7LOI
