SOTA alerts for this weekend

I’m planning to do 3 SOTA summits this weekend while we’re camping up on Independence Pass between Leadville and Aspen. Hopefully in the following order:

Saturday 8/18/2012 at 10:00 local Mountain time: W0/SR-108 using QRP 14.343 SSB and 146.52FM
Saturday 8/18/2012 at 14:00 local Mountain time: W0/SR-115 using QRP 14.343 SSB and 146.52FM
Sunday 8/19/2012 at 10:00 local Mountain time: W0/SR-020 using QRP 14.343 SSB and 146.52FM

I’ll have my TH-D72A beaconing to

I’m trying to pick up an Arrow Yagi for 2m. If I have that in time, I’ll try both FM and SSB on 2m.

Yaesu FT-817ND with Buddistick vertical

Made big headway today with my new setup. I had only made one contact so far and was getting frustrated. The SWR meter on my 817 showed nothing so I assumed everything was tuned correctly. I finally hooked up my old Micronta 21-525B gifted to me by K1LQH, and found my SWR on CW was 3:1! I shortened the whip about 12″ and immediately was copied 5-9 by a station in CT and another in MD!

10 meter antenna part II

I used Nylon rod turned on my lathe to mount the mast to the ground plate. I may switch to fiberglass later, but cheap is my goal and I had the Nylon and PVC pipe for the vertical. I used 14 gauge Romex stripped out for the conductors. At the top of the PVC I’ll add a plastic compression fitting to seal the copper that extends just beyond the pipe.

Homebrew 10 meter vertical

I’m working on a 10 meter vertical antenna for the roof of my house. It’s a quarter wave ground plane centered on 28.8 MHz, so it will be 97.5″ tall with 4 97.5″ radials. I used the formula Length of Dipole (feet) = 468 / Frequency (MHz). Since the radials comprise one half of the dipole and the vertical is the other half, you divide the length by 2.
I’m looking for some 1/4″ diameter fiberglass rod for the vertical. We get a lot of wind in Colorado so it needs to be tough. The base is a 1/4″ thick aluminum plate with a SO-239 bulkhead connector. I will weld on a round piece of stock on the top side, then turn it on my lathe as a receiver for the fiberglass rod. A length of 14 gauge stranded copper will live inside the fiberglass tube.
Here are some pictures of the base that I started on today:

Road Trip!

I got to spend 2 weeks camping with the dogs between California and Colorado. We hit up Zion, Bryce, Moab and the Dixie National Forest. Great trip!

High Park Fire photos

Here is a gallery link to the photos I’ve taken (and will take) of the High Park Fire burning near Fort Collins, CO.  This fire apparently started from a lightening strike that smoldered for several days, then roared to life early on Sunday morning, 6/10/2012.  I’ll continue adding photos to this gallery as I take them.

Element Bed, part 2

I am about finished with the construction of my bed, and it turned out as good as I had hoped for! It can be installed or removed in less than 15 minutes, and it retains all original functionality.

The rear legs support the bedframe against the floor of the Element.  They need to be removed to get the frame in/out of the car, and can be easily removed with a 7/16″ wrench.  I used Nylok nuts to keep them from vibrating loose.

I added Unistrut spring loaded nuts to the Honda strut rail where the original seats attach.  I did need to grind a tiny amount off the strut nuts to fit the metric rail.  These nuts can stay installed when the bed is removed.

Bed frame before paint and plywood.

Full view of bed frame.  The plywood is attached with #10-1″ self-drilling metal screws.  They fit the 3/4″ light-gauge square tubing very well.

Frame with plywood, getting ready to staple on the faux leather.  I used automotive headliner as the backer for the leather, to add a little cushion.  It turned out to be very comfortable to lay on.

Bed with front section folded back for travel.  The plywood measures 47″ Wide.  The rear section is 48″ long, and the front section is 24″ long.  I used a piano hinge for the joint.

I stapled continuously along the bottom edge.  I plan to make a lighweight aluminum trim strip for the visible section on the front folding section.

Honda Element camping / sleeping platform

Getting ready for a 2 week road trip from Colorado to California, then back through S Utah, I’m deciding it is finally time to outfit the Element with a proper bed. In looking under the trim piece where the rear seats attach, I noticed that a Honda-made unistrut piece exists! And, it is compatible with standard spring strut nuts. I am going to weld up a frame from 1″ square tubing, that will attach at these two points with wing nuts and all thread. There will be 2 vertical supports at the rear, and a piano hinge at the front, so that part of the platform will store folded over the back section, and will fold forward and be supported by the front seats. Puctures of that to come. My idea is to have full access under the platform for storage.

Radio parts for my near-space balloon project

I am assembling my own electronics for an APRS based weather balloon project. I’ll be launching a balloon with some friends that transmits various weather data and location via APRS ham radio, and also logs high resolution data via a basic stamp computer.
