Solar activity took a dramatic plunge over the recent reporting week (June 23 to 29) but geomagnetic activity stayed exactly the same. Field Day weekend saw rising geomagnetic numbers, with planetary A index at 8, 16 and 23, Friday through Sunday. On Sunday the geomagnetic activity was a problem, although not severe, with many stations in Field Day reporting increased absorption. The planetary... [...]

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 is one of those projects that has been residing in my head for a long time, as something I wanted to build. I’ve always liked direct conversion receivers. With them, as with regens, I felt that they have been underestimated by many builders and hams as being novelty items. Their apparent simplicity can also […] [...]
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 […] [...]
In this post from May of last year, I detailed the construction of a 1mW solar-powered HiFER beacon. I named it the Boris Beacon, in tribute to my neighbor’s cat. The beacon was never mounted permanently outside. I kept it indoors, powered from a small solar panel in the window, and feeding an “antenna” of […] [...]
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 […] [...]
To many, this will be just another Si5351 VFO project, with nothing to distinguish it from the others. In fact, that’s exactly what it is. The “how to” of connecting an Arduino board to an Si5351 board, wiring up a display, and loading the firmware, is straightforward, and well established. To me though, it was […] [...]
My build of the K7TMG HF Morse Code Thermometer was fun, and it inspired me to use the same circuit to create a new HiFER beacon to honor my neighbor’s cat Boris. With some of my indoor cat-owning neighbors in the past, I have acted as caretaker when their parents are out of town or […] [...]
This was a fun little project – and it gave me an idea for a future one. Sometimes, I find that the more complex undertakings, which require more planning, can get to the point that they “take me over” somewhat. At that point, for me, some of the fun starts getting squeezed out and that, […] [...]
Note – lots of photos, so please allow time for them to load! In a previous offering, I posted a few photos and a brief description of a QCX 5W CW transceiver from QRP Labs that I recently assembled for Fred, a ham friend. It was fun, because I got to assemble and experience first-hand, […] [...]
