“None Simpler” Etched Spirals Replace Coils

After being thrilled connecting up a Pixie 2 based QRP Miniwat ham radio transceiver circuit board purchased on eBay to random switches and plugs I had around my room (see the Resilient Freedom post about my “Bumble Bee transceiver“), I’ve been rereading some classic QRP books (low power designs–great for backpacking and solar off-grid use).

I’ve also been surfing the web for new projects.

One that looks simple for beginners to mess with is the NS-40. The initials stand for “None Simpler” on the 40 meter shortwave band, which helps confirm my hope of it being quick and easy to build. But it also has some innovative elegance.

“Why is it called the None Simpler? Because there are only 14 electronic components, and NO TOROIDS or COILS of any kind to wind - NONE! All inductors are incorporated directly on the PC board as etched spirals.”

Before ordering the NS-40, I plan to finish the Ten Tec 1340 kit at hand first. That will give me more power, tuning range and better reception than my Bumble Bee. But it’s still only 3 watts output.

To get an old-timey feel for radio history, here’s a tour of the AWA Radio Museum of gear that’s been in use up to 80 or 90 years, including a 5,000 volt spark gap transmitter.

    Hey, thanks for the mention of my little transmitter kit. I just stumbled upon your blog, and think it is very in-line with my thoughts on technology and ham radio.
