10th Anniversary Giveaway!

On April 30th, it will be ten years since the "W2LJ - QRP - Do More With Less" blog was born.

In appreciation for all who read this blog, I am going to give something away to one lucky reader. I have a new, mint condition, unused, complete sheet of fifty United States Amateur Radio stamps, issued in 1964 on the 50th Anniversary of the ARRL - Scott #1260. I am going to have the sheet matted and framed - ready for display on some deserving shack wall. All I ask is that you send an e-mail to w2lj@arrl.net - entitled "Blog Anniversary Giveaway". Include your name, call sign and mailing address.

Any Amateur Radio op worldwide can enter. I will package and ship the framed stamps to any destination that the United States Post Office will accept.

The names and call signs will be loaded into a software program such as RandomPicker on April 30th and a winner will be determined. The winner will be announced here, and then the framed stamps will be posted.

Good luck, and thank you for reading!

Wrist Rocket Redeux

I needed to re-spool the fishing reel on my antenna launcher.


My first version used a plastic tent peg as a platform.  The sling shot was held in place by a bolt and nut going into the handle from the bottom.  This ultimately proved to be a weak point as the plastic handle of the sling shot broke over time from the stress at that point.

So when I bought new fishing line, I also bought another 8 inch corner brace.



I cut a 3 inch section off the "vertical" with a Dremel tool and a cutting wheel. I then attached the sling shot and the fishing reel to the corner brace using hose clamps.  I may take off the hose clamps from the sling shot handle and replace them with tie wraps - not sure.  When I grip the sling shot handle tight in my right hand, the clamps tend to bite into my palm a little bit.  To secure it well would require a bunch of tie wraps, but it would make it more comfortable to use.

I've been practicing in the park and I've been getting my 1 ounce fishing weight to get over branches 50 - 60 feet high with no problems.  I have discovered one thing, though.  My fishing weights (not the one in the photos) are painted bright yellow.  I think I am going to re-paint them with a very bright orange paint.  The yellow ones are a bit hard to notice when they fall onto the grass amid a bunch of dandelions!

Hello Larry,

A short strip of bright red surveyor tape works well and is easy to see as it flies through the air.

Ah, great minds think alike:

I found that the open-face reel offers much less resistance to the flight of the antenna launching weight than using an closed-face reel.

This is really a great tool that every amateur should have in his toolbox.
