In my e-mail just now, I got the following:
Hi , Daniel
My name is Rick, and my call sign is XXXX. I’ve been a contester since 2004 when I became a ham, and I love it!
I wanted you to see this information from a friend of mine, Trippy, about a new contest that will be [...]

Every September, our ham radio club, ARROW, does a construction project. In the past, we’ve done a keyer kit, J-Pole antennas, and other small projects that you can complete in an evening.
This year, we’ve decided to build a low-cost version of the Arduino microcontroller called the Bare Bones Boarduino, from Modern Device. This is a [...]

Here are some more links to interesting Web pages I found by Twittering:

N3OX’s Remote Tuner Control. N3OX has added some servo motors and controls to a manual antenna tuner so that he can move it closer to the antenna, but still control it from inside the shack. Very inexpensive solution.
Band Plans for 900 MHz and [...]

Sonnet Lite Release 12 from Sonnet Software is now available for free download. The no-charge three-dimensional (3D) planar electromagnetic (EM) simulator is an excellent training and learning tool for those new to the analysis capabilities of EM simulation software. It is a fully functional software program based on the company’s full-featured Sonnet [...]

WD6CNF has a number of cool-looking programs on his website – hotamateurprograms.com. Most of them are Vista-compatible, and they are all available for free, including:

CW Decoder
Audio Spectrum Analyzer
Audio Generator/Audio Spectrum Analyze
Digital Voice Keyer
Simple Windows Packet Controller
DSP Audio Filter
Instrument Tuner
Dual Channel Oscilloscope
Dual Function Generator

I plan to download and try out the CW decoder at the museum. [...]

Dog Park Software is now offering two packages free of charge:

iSpectrum Audio Analyzer
MacMemoriesManager

The catch is that they’re unsupported.
MacMemoriesManager doesn’t support my IC-746PRO, so I haven’t tried it. I haven’t downloaded the iSpectrum Audio Analyzer yet, either, but it looks like it could be a nice addition to my shack if it will work on [...]

ShackBox is an all-in-one CD for amateur radio operators. Shackbox claims to include programs that will allow you to:

control rigs and scanners,
design antennas,
design PCBs,
etc., etc. etc.

The feature that attracted my attention is that it will run on Macs. Unfortunately, it only runs on the newer Intel Macs, and I only have [...]

I know it’s pretty dopey to do New Year’s resolutions, but I’m going to do it anyway. Maybe if I list them, I’ll actually get some of them done this year.

Build more. High on my list of things to build is “A Simple Regen for Beginners.” I even have the PC board already. I’d also [...]

Last October, I purchased a used, iBook G4 Mac laptop and promptly started looking for logging programs. I found one that was kind of expensive (MacLoggerDX); one that was free, but didn’t want to work so well (RUMLog); and one that worked OK and cost somewhere in between the first two (Aether).
I ended up [...]

Here are a couple of items from mailing lists I am on.
Free Spectrogram ProgramKen, K3IU writes to the Elecraft mailing list:
For those interested, Spectrogram is again available as Freeware. Richard’s website, says:
Version 16 is being made available as freeware to replace the older freeware versions of the software relied upon by the majority of Spectrogram [...]
