Smallest possible all-mode POTA kit?
Minimalist radio fun in the form of a challenge? Yes please. When @HamRadioCrashCourse proposed the 1 lb POTA Pack Challenge, he had to have known I'd take it as far as I could. An upcoming work trip presented the perfect opportunity. I prepped the "Classic Band" modified truSDX with audio amplifier circuit, larger display, and thinner/flatter filter design, and paired it up with a minimalist EFHW built from an SMA connector, custom PCB, FT37-43 toroid, and 140 ft of 36 ga PTFE insulated copper wire. A 300 mAh 3s LiPo fed it the rig power. I used the internal mic and the rig's now amplified speaker for phone operation, a capacitive touch key installed in the rig for CW, and a custom audio adapter made it possible to run digital modes. Here's the story of the activation. truSDX digital audio adapter: https://oshpark.com/shared_projects/L...
