My QSO with K4TWJ

Like everyone else I was saddened to hear of the passing of Dave Ingram. We've all been inspired by Dave's magazine articles, columns, and by his books. I'll always remember his QRP transmitter in a pen!
It was my privilege to talk to Dave once, on the air. I was on 30 meter CW with a brand new,scratch-built, HB QRP transceiver. I was in Virginia. I recognized Dave's call, and was thrilled when he came back to mine. I told him I was running homebrew QRP, and that I'd found inspiration in his articles. I know he was happy to hear that.
73 OM!
Dave's wife Sandy put a nice message on his blog: http://k4twj.blogspot.com

Some Real DX: Andromeda Galaxy, M31

I mentioned that Billy and I had spotted the Andromeda galaxy. The photo above (not by us) is sort of close to what we saw. The astronomy books usually show these spectacular images of Andromeda in all its glory. But those pictures come from long exposures through big telescopes. Through our little six inch reflector, Andromeda looks like a cloud, not quite as defined as the one in this picture. This picture is a 4 minute exposure through an ordinary digital camera using a 300mm telephoto lens.

It is a real thrill to look at Andromeda. That little cloud represents 300 billion stars, and they are around 2.5 million light years away. So when you look, you know the photons hitting your retina started their trip LONG before there were homo sapiens. Icing on the cake: A satellite went through the telescope's field of view just as was looking at M31.

Another nice thing about Andromeda galaxy is that you can see it with the naked eye (you have to know where to look!). Because of this, people have been observing it for quite some time. Here is the first known drawing of M31. This is the work of the Persian astronomer Al-Sufi, and was done in year 964. The Persians imagined a constellation in the form of a fish in that part of the sky. Note the little cloud near the mouth of the fish -- that's M31.

Until 1923 astronomers thought M31 and other "nebula" were just clouds within our galaxy. The thought was that the Milky Way was the only galaxy. But then Edwin Hubble got some distance readings (using variable stars) on Andromeda and realized that he was looking at an entirely separate galaxy. That was a BIG discovery.

Homebrew transistors, QRSS Blog, Shep Show, Nose as toubleshooting tool

Some odds and ends today:

Ed, KC2TYP alerted me to this one: Jeff, K7JPD, has a very intriguing blog post about homebrew transistors. I suspect AA1TJ will have a rig made of these things on the air within a week. Check it out:

There is a new blog for the Knights of the QRSS:

Dave in Ireland sent me a link to the Jean Shepherd show in which he discusses his first soldering iron: http://www.archive.org/download/JeanShepherd1975/1975_07_30_Soldering_Iron_full_show.mp3

Alan, WA9IRS, alerted us to a nice EDN article on using your nose as a trouble-shooting tool:

The Sabine Shack

How's that for a shack! Elisa rescued me from the frigid front porch and got the owner to agree to let me use this little building. You can see the VW solar panel in the window.

Here's the view:

Here's a little silent video we shot of the Sabine Shack:



The HW-8 runs of a 7AH Gell Cell that is charged by my Volkswagen panel. Antenna is a doublet fed by TV twin lead. The Blackberry provides internet access, and I can send in blog articles from it by e-mail.

Springtime on Mars (as seen from the Sabine hills)

Ian Sharp in Britain took this image at 0:54 UT January 4, 2010. The North Polar Cap is huge and obvious. The slightly bright region on the southern limb (top) is the dusty Hellas basin.

After months of looking at Jupiter, we now have a good view of Mars. On Saturday night we had a "Mars-rise" over Monte Calvo shortly after sunset. Mars is really bright now (explained below) and the distinctive red color really jumps out.

I didn't take the picture, but the shot above gives you a good idea of what I was looking at on Saturday night. The Northern polar cap was very apparent in my six inch Newtonian Dobsonian. It looked like it had a dark border around it. Martian North is at the bottom in this shot. It is Spring in the Northern hemisphere of Mars now.

Mars is now in a very good position for observation from Earth. On January 27, it will be in full opposition:

So hey, this is the time for those of you who are hoping to win the Elser-Mathes Trophy! Aim those Yagis and be sure to tune UP!
