Please note that the above photo is of my SW200, though Rod’s no doubt looks exactly the same. A few months back, I received this note from Rod KQ6F – Hi Dave – I very much enjoyed your review on this product. It was largely the reason I bought one. My application is AM […]
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 […]
Note that although the audio processor described in this article is intended primarily for Part 15 AM broadcasters, and perhaps also low power licensed AM broadcasters on a budget, it may also have applications for hams with their AM endeavors. I’m thinking of the AM enthusiasts on 160, 80, and 40. Some of them are ex-broadcast […]
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 […]
Since completing The Sproutie Regen in it’s basic form in August of last year, I have been spending lots of time listening to it, and also some time winding coils for extra bands. On top of that, I wanted to add some extra thoughts and observations on building it and instead of creating a new […]
A couple of weeks ago, I posted about some reduction drives I had acquired, including a classic National micrometer dial and PW gear drive, in nice condition. The PW drive has an output shaft that runs parallel to the front panel. Conversely, the drive in which the output shaft effectively runs straight through is called […]
I was quite excited when Aaron N9SKN told me he was building a Sproutie. Sometime earlier, I had discovered his website, billed as the “Home Of The 500mA Sidetone Oscillator/Shack Heater” I was searching for information on building HF receivers, and came across Aaron’s build of W7ZOI and K5IRK’s Progressive Receiver, as described in the […]
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 […]
As a follow-up to the previous post, in which I discovered that the Sony SRF-59, though cheap to purchase, offered surprisingly good performance due to a rather creative and interesting receiver architecture. I did some reading up on external antennas to help pull in weak stations. Among the Ultralight DX’ing crowd (those who DX the […]
After finishing the VK3YE Micro 40 DSB Transceiver, I did fool around with crystal radios a little, but didn’t pursue those experiments very far. Perhaps they will continue at some point. However, thinking about crystal radio sets did keep me on the subject of Medium Wave AM Broadcast Band listening for long enough to find […]
