When I built the VE7BPO DC Receiver Mainframe recently, it wasn’t intended to end up as a final finished project. The intention was more to have it as part of an experimental platform. The little box that contains the DBM, diplexer, and AF amplifier that make up the mainframe will most likely stay largely the […]
This will be a very brief post, and in no way constitutes a review. It’s barely even an “initial impressions” type of post. It’s just that I’ve been wanting a C Crane Skywave SSB for a while now, recently purchased one, and wanted to tell you! I’m sure many readers will identify with the search […]
Back in May of this year, Sheldon N6JJA began sending me information and details of his version of N1BYT’s WBR regenerative receiver. It went through several iterations, before ending up at the final version as shown here. Even this version is still a work in progress – as all good products of experimentation are. Sheldon […]
Andy and I have been communicating via e-mail since April. He is M6YAO now but back in April, he was plain old unlicensed Andy, who was about to apply for his Foundation License in the UK. He had built a Mark regen from Walford Electronics, which seems to have given him a taste for regens. […]
Firstly, I must apologize for posting so many pictures of these National HRO gear drives and dials. Once I decided that a building a regen with one of these dials and drives as the centerpiece was a goal, it became something of a preoccupation to find both a dial and drive that were just right. […]
The gradual (and selective) acquisition of vintage radio parts here continues, as I hone in on the perfect tuning dial and drive for my next regen, I’ve been wanting to find a really nice National HRO Micrometer dial and drive for the purpose, and have finally found it. I had to purchase 4 dials and […]
This morning, my 2 eldest kitties did a real number on me. The senior was the first. At about 5am, she sat on her food shelf (one of 3 shelves mounted on the wall next to my bed, specifically for the cats to hang out on), next to her empty food bowl and began meowing […]
I just knew that at some point, Jeff K1NSS would include Thomas Witherspoon, K4SWL in his Friends Of The Shortwaves series on Dashtoons. It was a no-brainer. Thomas’ blog, The SWLing Post has a very strong following and Thomas continues, through the blog, to make a strong case for the continued use of shortwave broadcasting […]
NOTE – Many thanks to Aaron N9SKN and Cliff WA9YXG, who pointed out errors in the schematics. They have been corrected. N9SKN, and several others, have built working Sprouties from the schematics in this post so rest assured that if you follow them, you can too. If you’re thinking about building this great little general […]
