In a recent activation I found I had forgotten my CW iambic at home. This is not the first time it happened to me and I decided to build a homebrew iambic that I would always carry in a pocket of my rucksack.
Its features should be:
very compact and lightweight
low profile to avoid any damage when stored and during the hike
simple operating principle and built unexpensive parts
rugged enough for portable and country side, and
capable of being operated with gloves
With all these features in my mind I decided to create an iambic using paper clips as the levers, because they are flexible.
I decided to avoid the standard iambic shape with lateral motion as they require more height. In the past I built one like that; you can see it here:
But this time I wanted another design. Instead I rather preferred building a vertical motion that requires a lower profile.
The paper clips are first opened, like this:
You can see that the clips can be opened in two different manners; it’s better to open them sidewards.
Then the system is assembled into some plywood, glued with epoxi to fix the paper clips to the base, and a thick aluminum layer (from an aluminum tray) is added to be in charge of closing contact with ground.
See the final part assembled here, with a final decorative touch on it:
In order to protect my Sota Micro paddle while hiking, I’ve built a little cover with EVA rubber:
It’s not difficult to get used to the vertical iambic motion. In fact, it aids to keep the paddle stable while sending because fingers apply pressure towards its seat.
You can see it working in this video:
Did I mention I saved a lot of money with this gadget? Since I started activating for SOTA, back in 2011, I’ve always carried homebrew paddles, and I think I’ll get on with that…
Now, I’m not really sure if my micro paddle will remain as an emergency / backup solution or if will become my main paddle on summits, hi
