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 […]
There are a few things I’ve been wanting to write about here. A couple of fellow builders have regen builds that I’m keen to relate. I have also wound two more coils for The Sproutie and would like to pass the details on, as well as a few thoughts on the subject, and coil-winding tips. However, […]
Followers of Jason NT7S’ blog “Ripples In The Ether” will know that he has been experimenting with the Si5351 chip. This little $1.50 (or cheaper) device is a PLL clock generator which provides 3 independently programmable outputs from 8KHz to 160MHz. While it’s phase noise is not quite as good as the Si570 (the chip […]
Since building The Sproutie a few months ago I have had a great deal of fun with it. It is only the 4th regen I have ever built, but it is the best one so far. One of my main motivations for building it was to own a “serious” regen. I have long thought that […]
About a week ago, Joel KB6QVI, tipped me off to the fact that Cecil K5NWA was selling 7.28MHz ceramic resonators on his online site, The Parts Place. Enthused, we both ordered some, and both our orders arrived yesterday. Joel slipped his into a test circuit, which gave him coverage of 7.015 – 7.236MHz. He used a […]
