The portable ‘shack’ in the field — and the need for a keyer

I took the completed portable shack that I’ve been working on into the field last weekend. It was all setup and working in about 15 minutes. I was on for about 4 hours on 17 meters and talked to about 15 contacts across 3 countries on SSB. I was focused more on playing with the settings and options than actually making contacts so I was pleased with the performance, overall.

I did realize there was one thing I wished I had and that was a disposable iambic keyer. I have a nice keyer at home for sending Morse code, but there was no way I was leaving it in my portable shack box or (more likely) forgetting it at home so it wasn’t there when I need it. Once again, it was time to call on the 3D printer.

keyI came up with a design fairly quickly that used about a dollar’s worth of spare parts I had lying around and half a hacksaw blade. I printed out a couple of samples to refine the model. By the time I had the second one done, I declared victory and now have a small iambic keyer. It is a simple keyer without squeeze functionality, though there are some designs out there that do that. The only real refinement I’d make is to create a tunnel in the base to run the wire through, rather than using a zip tie on the post where I screw down the hacksaw blade. We’ll see if it is ‘good enough’ in the field, next time. I’ll likely screw it into my clipboard.

If you are interested in the iambic keyer design, I uploaded it to: thingiverse

Some people probably find it hard to believe that there are still folks that operate CW, but it has its own challenges and can get the message through when little else can. I used to operate CW a great deal, but am a bit rusty now. We’ll see if having a keyer like this helps.
