Simple and better circuit for MiniWhip antennas?
« on: December 20, 2022, 1812 UTC »
Boomer FWR this to me. Looks easy enough, and if I was stuck as an apartment dweller, IŽd build and try it. http://www.pa3fwm.nl/projects/miniwhip/

Since I did electrical training, for being an electrician, decades ago, I thought that I could always fall-back on that. Besides, what other field can you use trade terms like nipples, hickeys, and making male / female connections, without getting into trouble at work?

Or you could purchase a kit or per-assembled version manufactured in North America for a very reasonable price.

Is this the antenna he has in the bread bag up the tree, Mister Dood?

BTW, I was in contact with the guy's at the University of Twente when they first got their SDR up and running, I'd never heard of one of the things. One of the guy's was interested in the Grenade transmitter, he'd seen an online schematic. I gave him a few parts corrections from Boomer's hand drawn schematic and he built one. He was the first person I encountered that realized it was a Class-E device.

I'd hit him with an email when I was heading out to transmit and while he never got any audio, he could point out the carrier every time, which amazed me as you know how low powered the things were. I don't know what kind of antenna they were using then.

He used his Grenade for short-lived pirate station until he graduated. I hope it's still in use somewhere.
