I got married, on 26 April 2003, to a lovely lady whose name now is
Melody Andrews. She wanted me to put a photo of her on the site; I am perfectly happy to do so. We're coming up on our fourteenth anniversary. It's good! |

| Robert, WA5CAB, very kindly provided a TIF file of GE Ham News for May/June 1951: Transmitter Tube Testing, for those who want to build test rigs for their transmitting tubes. | Robert, WA5CAB, also very kindly sent me a TIF file of the data sheet for an RCA 8122A transmitting tube. | Need a custom transformer, or just interested in how they're constructed? Here is an article on deconstructing, disassembling, designing, and making your own. Thanks to Paul Kraemer for the PDF file! |
On May 10, 2010, there was a significant outbreak of tornadoes in
Oklahoma. Here is one of them, photographed by Melanie Herbert,

Oklahoma City:

It appears here by his kind permission. | The ARRL used to put out a little 4-page booklet titled "Your Novice Accent", to provide guidance on operating procedures to newly-licensed operators. I sure wish I'd had a copy of it when I got my Novice ticket, back in 1962. Here's a scan of it. |
If you're interested in storm spotting, or in listening to what's happening
while there's severe weather in your area, you might want to print and post
the relevant pages from this site: USA storm spotter radio frequencies, by state for reference. These may be a bit out of date, but could provide a good starting point. |

Stories | Lots of amateur radio operators ("hams") work with electronics in their day jobs, too. Many of them have stories. I'm trying to collect them. Look for them here. If you'd like to contribute, please send mail to me here: mikea@mikea.ath.cx . | |||
| Mr. T, W9LBB, told about working at a capacitor factory. It was hair-raising in more ways than one. Read about it here. | Mr. T, W9LBB, also was involved in testing really big high-voltage power supplies. That story is here. | This one happened to me. If you're a news crew and you need bright lights, how do you know if that wall socket will supply enough Rich, Chunky Amps? This is one way, but I don't recommend it. | Ben Dover wrote about taking the FCC Second Class Radiotelegraph Operator's exam, back in 2006, here. | |
| Here's another that happened to me, illustrating a side of amateur radio that does not make us hams look good. The bad actor(s) got a comeuppance, too. | I suppose that you could use the heat from the power tubes in your final to make coffee. Here is a rig that could have done it easily. |
Not ham-related, but a major missed opportunity. |
Sometimes people get a bit cocky. This is the story of one such, and his comeuppance. | |
| This one happened to other folks at my day job. Talk about pothole repair! | Life on the ocean wave can get very boring. Carl, KM1H, did something about it. | Sometimes radio ops wind up chewing the rag when they should be doing something else. | Kids learn languages very quickly, especially when given incentive, | |
|
KU4AF, John, tells about a net I'm not in a rush to join. |
Sound advice posted to the glowbugs mailing list by Ron D'Eau Clair. | Abbreviations can be misread. What you meant and what the op at the other end thought you meant may be two different things entirely. Read about one instance of that here. | David Ring had some good stuff to say about Straight Key Night (SKN) here. | |
| Hans, K0HB, had an interesting experience when taking his Amateur Extra Class exam. | The "slap, slap, slap" of signal light shutters. | Submariners got into the act, too. | Jim, N2EY, tells a tale of a different sort of secret communications, in Daisy and the Dynamotor | |
| Jim, N2EY, reappears with a tale of life in his high school, titled Graduation and other events | Every 2500 hours or so, you need to check the oil in the transmitter. | Hans, K0HB, copied CW as a radioman. Then he started hearing it in his bunk. | The Golden Comma award went to CW operators who didn't follow the rules. David Ring has a bit to say about it. | |
| Sam, N9FUT, stopped traffic sometimes with his transmitter. | Dick, W1KSZ, tells about ... well, about a bug in a Bug. | Chris Suslowicz relays a colleague's story about working at a BBC radio site where Voices Were Heard. | Chris Newport, G4JCI, found that professional radio operators have problems that amateurs just don't have to worry about. | |
| They don't make school field trips like this any more, I'm told. That's a real shame. | "Percussive maintenance", a.k.a. "brogan maintenance", sometimes does locate faults, as Bob K1BC tells us here. | Sometimes the janitors locate faults, or at least cause a pending fault to surface. In this case, they used a mop bucket as a tool. | Most transformers are small enough to hold in a hand, bigger ones may require a forklift to move, and really big ones move around on a 53-foot semitrailer. But one turned out to be bigger than a football field. | |

| For an F-105 to get into the air, a great many things have to work correctly. Here is a story of one thing that didn't. | Some of the places I was sent, weapons familiarization sometimes got short shrift or lip service. | Aircraft, like arrows, have to be put together very precisely if they're to fly straight and true. Some had ... well, problems in that regard. | Units of measure sometimes change, as a friend found, from "each" to "set" | |
| Most swords cut both ways, as this story illustrates. | ||||

| The National Security Agency has declassified some books recently. Spartans in Darkness, one of those books, is a (heavily redacted) history of SIGINT operations in Viet Nam. Even with the very many deletions, it still is illuminating. | I happened onto a copy of a US Army World War II training code. Here it is. | Sometimes remodeling doesn't go smoothly. | When you short out a 480 VAC 3-phase feed, things can get interesting. | |
