Earthquake… again…

October 30, 2007 | General | By: Mark VandeWettering

Yep. Another earthquake. I had just gotten of the phone with Carmen when I felt the slow, periodic roll of an earthquake. The shaking was relatively slow but fairly large in magnitude, and persisted for nearly ten seconds. The cat was not particularly happy with the shaking either, and he meowed to be let out […]

First QSOs via AO-51

October 29, 2007 | General | By: Mark VandeWettering

Well, I’m not much for operating really, but I have been trying to work up the courage actually talk on the AO-51 amateur satellite.  It was down from October 18th, but today was back up and running the repeater.  I am still using a handheld Arrow crossed Yagi, so my hands are pretty busy, but […]

AO-51 appears to live!

October 29, 2007 | Amateur Radio | By: Mark VandeWettering

I was going to present a link the cool OSCAR Satellite Status page by KD5QGR because it can be useful for beginners to see which satellites other amateurs are hearing. If you’ll notice, for a long time only telemetry was being heard on AO-51 (the easiest of the LEO satellites), but in the last few […]

How I track satellites…

October 29, 2007 | Amateur Radio | By: Mark VandeWettering

I was chatting with my brother about my recent attempts at satellite tracking, and he expressed the opinion that it would be nice to present some of the details about how I actually figure out where satellites are. I’m not sure that my methodology is particularly noteworthy, but here’s what I use: There are lots […]

Buried in an AO-27 Pileup

October 28, 2007 | Amateur Radio | By: Mark VandeWettering

Well, I’m trying, but I’m finding that I need a third hand to work satellite handheld. Maybe some kind of tripod ala K7AGE would free up my hands enough to be able to be a little more calm. I managed to get my call out, but I failed to copy the responder’s call properly, so […]

Batting averages

October 27, 2007 | Baseball, Math | By: Mark VandeWettering

It’s the third game of the World Series, and the score is tied 0-0. If you can’t find any enjoyment in the reality of the game, perhaps the theoretical niceties of the game might provide some distraction: 11011110: Batting averages Me? I enjoy both. Technorati Tags: Baseball, Mathematics

Programming the Kenwood TH-D7A

October 26, 2007 | Amateur Radio | By: Mark VandeWettering

Modern ham transceivers are complex. Really complex. They have dozens and dozens of settings, hundreds of memories, and they are kind of a pain to program. That’s why most radio manufacturers now include an ability to “clone” a radio from another one, and perhaps even a way to actually use software to design a configuration […]

First Successful Satellite Communication!

October 24, 2007 | Amateur Radio | By: Mark VandeWettering

Hey, a milestone for me. During my morning commute, I managed to actually send a position report to the amateur radio satellite GO-32, which got picked up by W7KKE in Lincoln City, Oregon, a distance of 810 miles, not bad! I wasn’t sure it had worked, but I noticed that I had received some packets […]

More Satellite Stuff…

October 21, 2007 | Amateur Radio | By: Mark VandeWettering

Well, I haven’t had a lot of time to do anything good this weekend. I spent some time mowing my lawn, pulling weeds, fertilizing, and examining my fence for needed repairs. But I did spend some time to actually figure out what my problem was with receiving signals from the AO-27 amateur satellite. It wasn’t […]


October 21, 2007 | General | By: Mark VandeWettering

I spent yesterday wandering around Pacificon. Nothing too exciting to report: I picked up a book or two, no major purchases. The QRP related activities were a lot of fun, and I managed to win a bid for a BLT tuner kit from . Oh, and I decided to try to upgrade my Technicians […]

The photon/XOR system

October 16, 2007 | Computer Science | By: Mark VandeWettering

It’s 8:22AM, and I’m just waking up, checking my email and surveying my usual blogs with Google Reader. I don’t have time to explain why this link seems interesting, but if you are interested in random walks, computability or cellular automata, check out the following link. I haven’t had time to absorb it yet (and […]

Haskell Workshop 2007

October 15, 2007 | Programming Languages | By: Mark VandeWettering

In a break with my recent focus on radio related topics, I return to another topic that I’ve enjoyed before. The 2007 Haskell Workshop has made videos of many of their talks available. Some of it looks pretty nifty. Enjoy! Haskell Workshop 2007 – List of Accepted Papers

AO-51 Crashed?

October 11, 2007 | General | By: Mark VandeWettering

From the AO-51 status page: AMSAT – AO-51 Control Team News At 1848Z 11 OCT over Europe, the software on AO-51 crashed, shutting down both transmitters. Subsequently the repeater and BBS will be down for several days while the command stations reload. Sorry for any inconvenience. I’m bummed.

Hey, I can hear AO-51 from my car…

October 8, 2007 | Amateur Radio | By: Mark VandeWettering

I noticed that a 56 degree elevation pass of the amateur satellite AO-51 was going to occur just after 9:00am this morning, while I was commuting. I normally carry my little VX-3R with tiny mag-mounted dual band antenna on the roof. This is the same gadget that I used to receive the AO-51 broadcast of […]

FCC-1 Assembled

October 6, 2007 | Amateur Radio | By: Mark VandeWettering

Last week I got my FCC-1 kit from the Norcal QRP club. It’s a nifty little PIC based frequency counter, and is quite inexpensive. It’s not very hard to assemble, but I still managed to have a couple of minor problems. Hint to anyone assembling the kit: REMEMBER! The switches are soldered on the wrong […]
