We share several of our UHF bands with unlicensed services, and from time to time, you’ll encounter those signals on the bands. Another reason to be familiar with them is that there are companies that have their eyes on them.

The C. Crane Company has for many years sold radios that they claim have superior AM band performance. They used to advertise a lot on the Coast to Coast AM radio show, touting how the radio was capable of pulling in the show, even if your local station didn’t carry it. They probably still do, [...]

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 [...]

For our Ham Radio at the Hands-On Museum project, we want to set up a television station. My first thought was to buy a transmitter from PC Electronics that sends standard-scan analog TV. Then, I got to thinking, why bother with that? If our goal is to show that we’re at least up with current [...]

From the April 3, 2009 ARRL Letter:

According to AMSAT-DL President Peter Guelzow, DB2OS, the Earth-Venus-Earth (EVE) transmission is another step in preparing for a mission to [...]

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 [...]

Someone recently offered to give our club a 900 MHz repeater. 900 MHz?? Who uses that band Well, apparently, there is a lot of activity up there, and maybe the least of it amateur activity.
I got to thinking about how we might use it. The first thing to cross my mind was digital TV. [...]

On the HamRadioHelpGroup mailing list, a ham asked:
Will a CB SWR meter work on a 2 meter ham radio??
Mark, K5LXP, replied:
Yes and no.
I use a CB SWR meter to check 2M antennas all the time. There is a trick to it however.
If all you want to to is check SWR on your 2M antenna, [...]
