How to Grow A Rohn 25G Tower PART 2

Welcome back! If you are reading this, you are either here intentionally or the Google machine sent you here by mistake. Either way be sure to sit down and strap in because this is going to be an exhilarating experience!

So my fancy book readings told me that due to the magical properties of  concrete, you should build a box out of rebar and pour the concrete around it. Concrete has great strength in compression, but doesn’t have nearly as much strength when tension is applied. To remedy this, we add the magical properties of steel. Steel is STRONG in tension, so by building a box out of the stuff and pouring concrete around it, the steel takes the tension and “the crete” takes the compression. By putting some blocks/bricks/books/bills under the rebar cube, it will ensure that the box sits off the gravel base and no rebar ends extend out past the edges of your concrete cube. This is important so that moisture doesn’t rot away the rebar over the years, thus compromising your tower cube and possibly the tower’s structural integrity itself. read more

2018 Hamvention, ~Fin~

Well it looks like Hamvention just came to a close for the 2018 year. All prizes have been handed out, and all hams will start filing out of the building. Thanks to all of the DARA members that worked hard to put it on, everyone that attended, and to our OVEC members that were able to participate in the badge printing process to help fund the club for another year.

A special thanks goes out to our Vice President Ben, N8BD, for keeping everything moving in a forward direction and helping to resolve any issues that came up over the duration of the event.

I hope everyone had a great time, and look forward to doing it again in 2019!

73 Everyone

HAMVENTION 2018!

Hey folks! It’s that time of the year again, and we are at it again printing badges to fund our club for this year’s events. Want your own custom printed ID badge? It comes with a picture of yourself on the front, two radio related logos, your name, callsign, AND a current copy of your reference license printed on the back! HOW COULD YOU POSSIBLY SAY NO TO THAT?!

Come see us in the Flea Market for yours TODAY(and Saturday, and Sunday)!

How to Grow A Rohn 25G Tower

Well as with all flowers, spring is the best time to get them in the ground, and a Rohn tower is no different. You must make sure to plant no sooner than the final frost, or there is risk of your antennae wilting and falling off the tower.

Joking aside, we have lived in this house for 5 years and my Rohn tower has done nothing more than sit under the deck and collect more tower sections as I take other towers down. This is all well and good, but as an amateur radio operator I should probably have a place to put my antennas. So let it begin…

Step one when building a tower is finding a good place to put it. I did that, so step two is DIGGING A HOLE.

Now there are 3 main ways to dig a hole in the crust of our planet, but the most efficient one is to rent a backhoe and pay a man or woman to do it for you. Well I am cheap and slightly overweight, so the next best way is with shovels and a lot of hard labor. I dug this hole over the period of a year. I dug half one day in August of 2017, and the other half today!  Shovels opted for were a round nose, square nose, and a non-shovel, the “spud bar”. Little known fact of the spud bar, it will destroy you. A few hours of using it to bash rocks, and break dirt will turn even the manliest of men into a crying toddler, much like myself. That aside, your manly essence after using one of these things will waft through the countryside, meaning all the single ladies will be bangin at your door. Married men look out, you’ll have some splainin to do… read more

Repeater Live Feed Functional!

Well as with many things, getting the live audio feed from the repeater working ended up being a fiddly process, but it was a learning experience every step of the way. Feel free to check it out on the right side of this page!

The current setup is a Raspberry Pi running Raspbian, with an older scanner feeding the audio into the Pi, and then being uploaded using DarkIce to the Broadcastify servers. This offers a pretty small physical footprint, with low power usage, and makes it relatively bulletproof. In the future I look forward to getting everything reconfigured utilizing a USB SDR receiver, which will eliminate the need for the external scanner and the required power, since the USB SDR stick will be powered off of the Pi itself!

Once I finally get all the little bugs worked out from this project, I hope to build up a second Pi with an SDR receiver that can be web controlled. But, we shall see! read more
