Code Proficiency Programs: Do We Really Want/Need Them?

In the wake of the recent decision to eliminate the Morse Code requirement, there have been several proposals to set up code-proficiency testing programs. I just got an e-mail today from our division director proposing a pilot project that VEs would be responsible for running in the communities they serve. And there has been some [...]

EEs in Training Get Some Hands-On Experience

When I was an electrical engineering student back in the 1970s, I was surprised at how many of my peers had little or no practical experience with electronics. Of course, I had the jump on them since I got my ham ticket when I was 16.
Well, apparently, times haven’t changed a bit. At Berkeley, some [...]

Yet Another Take on SMT Soldering

Here’s yet another take on SMT soldering using a convection oven: SMT Board Fabrication Project. What makes this page nice is that KD5NWA, the author of the page, includes lots of pictures.

Even More Fun With Baluns

After my successful experiment with winding a 4:1 balun, I started to think about how to package the balun.

More Fun With Baluns

I’ve written about building baluns before. I’m still quite proud of myself that I was able to build and deploy a couple of nice 1:1 baluns.
Of course, the next challenge is the 4:1 balun. I even bought a couple of AB240-125 kits to build one. Since my 40m dipole came down in the ice storm [...]

Two UTC Clocks

On one of the many mailing lists I’m on, someone asked if there was a simple clock program out there that would display UTC. Well, it just so happens that Vic, K2VCO, one of the regular contributors to the mailing list had written one. You can find it at http://www.qsl.net/k2vco/. It displays both the date [...]

This Weekend on the Radio at KB6NU

I wasn’t all that active this weekend, and in the next week or so, I’ll be even less active, on the air anyway. Let me explain…
Contests and More Contests
Last weekend was the CW portion of the North American QSO Party. I had several things to do on Saturday, including helping to get our latest Tech [...]
