Building Things – QRP Gear: Dummy Load, Antenna Tuner and QRPometer

As part of my interest in QRP low power work & gear, I’ve been putting together a few kits as I assemble a viable QRP station.

First to dust off the soldering iron, a simple Dummy Load kit was tackled a couple weeks ago. Took me more than ten minutes, but then I had to find & set up my gear too!

Next put together was a Summits On The Air (SOTA) style antenna tuner kit. Technically this one isn’t quite done, as I have the back-of-case label to sort out. I want to confirm the antenna lengths & setting for various frequencies myself before doing a label.

This weekend I snuck a bit of time and put together what looked to be a harder kit, but turned out to be pretty straight forward. The QRPometer is a SWR Meter kits designed for QRP use. I want to reconfim my calibration one more time, then there a few final steps beofre it is fully mechanically assembled. Thinking of upgrading my kit to use BNC connectors rather than the supplied RCA ones before the final bolting together.

Next up is a Small Wonder Labs Retro-75 and Retro-Helper VFO kit.

I gave away my QRPme setup (Two-Tun Tuna & Sudden Storm) but have another set unbuilt, so those may follow.  Already complete is a Small Wonder Labs Rockmite in a MityBox enclosure.  I’m not happy yet with the American Morse key I put together and I have to knock it down and get agressive on lapping the paddles for clearance.

Slowly coming together, and will eventually be a complete multi-ability QRP Station in a Cigarbox for grab-n-go QRP fun!
