Stacking Tower

I'm way behind on updating here.. The tower itself is up. I home brewed my ginpole using an actual gin pole head I bought on ebay.  I added a 10 foot section of 1" galvanized pipe.  I didn't buy any brackets, so I used u-bolts to attach it to the tower.  Not recommended.  And I… Continue Reading

  1. Nice, now just don’t move in a year! 🙂 Will the ginpole serve as a lightning rod? Or will physically be breaking the circuit from your antenna(s) to your HAM shack when not in use? (I’m sure I learned something about how to handle that when I took my Technicians, but I’ve forgotten)

  2. Last time I built a tower we DID move. A friend here built a really nice tower last fall, he had about $12,000 in it. Very nice. Never even got the coax connected and he’s moving to Florida.

    The ginpole is just a temporary fixture to for lifting the tower sections and antennas up, then it will come down. I just u-bolted the pipe for the gin pole to a tower leg, which wasn’t ideal, but it worked. If I ever build another tower I’m buying a proper gin pole bracket.

Tower Construction – Part 2

Some photos this time around. To build a tower you have to dig a hole.  A pretty good sized one.  In my case a minimum of 30" square and 48 inches deep.  No problem.  In normal soil. I don't live on "normal soil".  Our neighborhood is notorious for limestone.  Even the electric utility had issues… Continue Reading

The Shack

I just realized that there are no pictures of the shack on the site. The shack is very small.  We don't have much usable space in the basement, so it was a challenge to set up an area for radios.  It was decided to carve out an area just over 6' by 6' in one… Continue Reading

  1. Thanks, Josh, for the invite. Although I don’t know a thing (other than digging a hole, I’ve done that plenty of times in my life) about what you are talking about, I will sitll read and learn.

    Build away, dude.

    • ke7fyn – you really need to find a cheap 10m rig. It’s a blast when it opens up in the evenings. They can be had for under $100, and you can get a cheap CB antenna at Radio Shack for $30 or $40 and trim a couple inches off and be on the air.

  2. yah I should. I really need to test for my general or extra class. I could probably study for a day or two and have my general.

  3. I took the general the same night as my technicians. I was one question away from passing. That was about 4 years ago, so it would probably take some work now.

Meteohub

I've been working with some nice software called Meteohub to interface a Peet Bros Ultimeter 2100 to the Internet.  Meteohub was originally written to run on a Linksys NSLU2 NAS device, to provide a low power, low cost, very small form factor device. It's a great concept, and works great, when it works. The problem… Continue Reading

  1. How did this work out for you?  I am using an NSLU2 for meteohub but it is very slow and I've gone through a couple of USB drives.  I'm concerned about the power use, did you measure it?
     
    Thanks!

  2. Interesting timing on your comment..

    It worked great, until lightning took out the power supply and the ethernet port. 

    I used an off the shelf 4GB Compact Flash card I picked up at Walmart, and never had any issues with it. 

    I'm in the process of rebuilding on an older EPIA Mini-ITX system.  Just waiting on the proper IDE to CF adapter so I can plug my card in.  As I recall, that PC was drawing in the neighborhood of 13W when I was using it in the past as a Linux based firewall with a 3.5" hard drive and an extra ethernet adapter, so I'm expecting about 8 or 9 watts with this build.  Hopefully my adapter will arrive in the next couple days. 

    Stay tuned..

I have some tower sections

I now have three 10 foot sections of Rohn 25G tower sitting in my yard. I hope to get started soon getting that thing up in the air. I still need a 36″ house bracket. Rohn gets $249.00 plus freight for their heavy duty “universal” model which supports both Rohn 25 and 45 (more on… Continue Reading

Just a quick update

I have a "new" (actually refurbished) ATV modulator to mess with.  It was donated to me by CadCo systems, and has firmware that allows it to be frequency agile.  I hope to get a chance to mess with it soon.  I will defiantly have more to say about this. I'm starting to cook up some… Continue Reading

ATV

For as long as I’ve been involved in amateur radio I’ve wanted to get into Amateur Television (ATV).  I just never seemed to have the money to get started. Now that DTV has made NTSC Television more or less obsolete, there is starting to be some surplus equipment available.  I suspect that more and more… Continue Reading
