NJORP's "Chat with the Designers" Podcast

N2APB and N2CX of the New Jersey QRP Club have been hosting weekly, live, on-line technical discussions called "Chats with the Designers." They are recording these sessions, and turning them into -- in effect -- podcasts. Yesterday I listened to their session on circuit simulators and really enjoyed it. Today, I'll be listening to the one on digital modes. I think you guys will like this. Lots to learn from the NJQRP guys:

A Rare Tour of the HP Garage

Kim, VK5FJ, sent this to us. Amazing pictures. Inspiring! Look at that work bench. Note the ARRL antenna book.

The Allen Telescope Array

I'm really getting into the SETI Live project. Whenever I get a chance I go to the SETI Live page, log on, and classify a few signals. Today I was looking at the tech aspects of the antenna array. Very interesting, and very appealing to homebrewers. They are making use of dishes that were made for TV reception. And they are using software-defined receiver systems. All of this makes upgrades relatively easy.

Jill Tartar of "Contact" fame is running this project.

So, I'll be I'll be using a big array to listen (watch really) for the REAL DX on .5 to 11.2 Gigahertz. I'll let you guys know if I hear any "new ones"!

UK Balloon Launch and a North Sea Splashdown

I like balloon projects.

SETI Live!

Wow, this is really very interesting. The Allen Telescope Array (seen above) is back in operation and they are looking for on-line volunteers to analyze the signals that are streaming in. But unlike the now-familiar SETI-AT-HOME screensaver system, in SETI Live, they want you to personally evaluate signals -- very recent signals -- from the Allen Array. You'll be looking at waterfall displays similar to what we see with SDR rigs. They want you to mark and classify the signals and then upload your work. They are trying to screen out terrestrial sigs, man-made satellites, etc.

This is just the thing for those days when the solar flux is low and 17 meters is dead!

Planets Galore!

Good times for astronomy in Northern Virginia. The temperature is freakishly high, and daylight savings time has pushed the darkness into my early-morning shack time. My telescope troubles are sorted out, and I just discovered that with my current contact lens prescription, my right eye is much better for telescope work than the left. (Who knew!) I found an excellent and inspirational book on astronomy: "The Four Percent Universe." And this morning, while fooling around with my Stellarium program, I noticed that Saturn is high in the South-West before dawn. Coffee cup in hand I went out and was rewarded with a spectacular view of the ringed planet. I could even see one of the divisions between the rings. Titan was also visible. Last night Maria and I were looking at Mars. I can make out the ice cap and (vaguely) some the big valley features. No canals.

Happy Pi - Einstein Day!

The card is for a special event sponsored by the Lake Effect Amateur Radio Club:

I've been reading "Math and the Mona Lisa" so lately I've been more into Phi than Pi. When will we have Phi Day? January 6th?

Twisted Waves Across the Venice Lagoon

I don't really understand the physics behind this, but it seems to be important. And the video is a lot of fun. There is much Italian brio and bella figura in this. They even got Princess Elettra Marconi involved. And the video features audio from Marconi himself.

Mars in Opposition

Jupiter and Venus are getting all the media attention because they happen to appear close in the sky, but Mars is the real object to see this month. It is in opposition (see diagram). This happens every two years. Last time we were out in the Sabine Hills north of Rome (sniff, sniff).

I cleaned the 6 inch mirror on my Dobsonian telescope a while back, and when I put the whole thing back together, something wasn't quite right. I was getting dim and blurry views. So yesterday I went into telescope maintenance mode and, as the Brits would say, got it all sorted.

I was out looking at Mars last night. The view is not nearly as spectacular as the image above, but it is very nice. But I can't see much of the northern polar cap -- it is, after all, summer time in the Martian Northern Hemisphere.

Ralph Baer, Electronic Wizard

Here is a another nice video, this one about Ralph Baer, one of the pioneers of video games. At age 90 Ralph is still creating things at his workbench.

Amazing R/C Airplane Video From Germany

Wow, this is real techno-art. Take seven minutes, put it on full screen, crank up the audio and sit back to enjoy a unique aerial view of a beautiful part of Germany. Thanks to Bill, N5AB, for alerting us to this.
