Small Wonder Labs SW 40
The SW-40 is a wonderful kit, and a
nice rig to operate.
If you want to lean a bunch and like to mod your rigs this is a nice little rig to play with.

I built the SW 40+ to have something to
play with and mod a bit. There is also the nice Elmer 101 series of
lessons available. I have been away from radio for a while, and
this looked like a nice kit to get me feet wet again.
I housed it in a slightly over sized case, Actually the case is an
old AB printer switch box. This leaves more room for me to add a
keyer, and other mods to it, as I have time and
ideas.
The radio is a
joy to use. It has a very sensitive receiver.
Planed Mods
- Built in Keyer
- Zero Beat Indicator
- Digital display
- S Meter
- Adjustable Power Output
- More Band Spread
I like to have variable audio on my qrp rigs. I added it to the stock SW 40 by adding a 1K pot to the audio output. This makes the rig much more enjoyable when working strong signals.
