Saturday morning, I had the good fortune to have breakfast with members of the Michigan QRP Club.
I’d always meant to get to one of their monthly breakfasts (held the first Saturday of each month), but they normally take place in Flint, which is about an hour away. Only when they decided to hold one [...]

The Transistor Museum’s tagline is “Dedicated to Preserving the History of the Greatest Invention of the 20th Century,” and it does a pretty good job of it. On this website you’ll find articles on:

The First Germanium Hobbyist Transistors
Early Transistors at Motorola

Here’s a cute article on the use of ferrite beads written by a couple of engineers at Intersil. Some interesting stuff about why ferrite inductors work so well.

Ricardo, CT2GQV, writes the blog, The “Speaky” HF SSB transceiver and other homebrew projects. I found this blog because Ricardo linked to one of my blog posts.
I like it a lot. Ricardo is a hard-core homebrewer, and has posts on a number of projects including:

0-500 Khz converter to 4 Mhz
100 w dummy load
Attenuator [...]

Building is a lot of fun. You can build your own stuff, or take advantage of the work done by other hams and build projects from the ham mags like QST or CQ. One of the advantages of building projects from magazines is that frequently someone has already designed a PC board for it.

Hams sometimes bandy about the term “phase noise,” but few hams really understand it. Most of us can figure out that less phase noise is better than more phase noise, but that’s about as far as our knowledge goes.
To help you understand the concepts, there is a paper about phase noise on www.rfic.co.uk. While there [...]

Previously, I blogged about what every ham should know how to do. On a related note, the HamRadioHelpGroup now has a thread on what every ham should have in the shack. This is actually a revival of an older thread; the original poster, Jean, W4TYU, is now an SK.

From Terry, WA0ITP via the qrp-l.org mailing list. I’m thinking about getting an HF Test Set myself:
With the Holiday season upon us, it seems appropriate to provide an update of the Four State’s kit status.
