I couldn’t believe my eyes when I saw it or held it – just how small this kit is. Tim (N7KOM) and I met up in December 2023 when I was on a trip in the Pacific Northwest and he and I stopped for a lunchtime activation.
His kit is super light and small. I’ll let Tim take up the description from here:
A Pocket HF Go Kit.
by Tim (N7KOM)
There are few pleasures in life more satisfying than making QSOs on a thin wire tuned for a half wave.
One of my favorite radios is the classic MTR3B. At 9.8cm x 6.5cm x 2.4cm it is truly a pocket radio. Everything I need to get on the air fits into an Amazon external Harddrive case. Here’s a breakdown with weight measurements:
- MTR-3B – 126 g
- 9V Li-Poly USB-C rechargeable battery + power plug – 29 g
- K6ARK 3D printed paddle and 3.5mm cable – 22 g
- Earbuds + external volume control knob – 26 g
- Trapped EFHW on an RCA connector (matching the radio’s connector) tuned for 20m/30m/40m. 28-32 ga wire on a 3d printed winder. – 42 g
As is, it weighs a total of 323 grams or 0.7 lbs. Add in a lightweight 9 foot mast from ali-express and I have everything I need to make contacts. I could even string the wire on some bushes or the ground if I was really in a pinch.
I could reduce the weight and packability further by using shorter cables on the earbuds/volume control as well as the paddle cable.
The antenna winder is a K6ARK 3D printed winder printed at around 70% size.
A 41 g external speaker may also be added to the kit, but it does not fit in the HDD case and must be carried separately.
Here is a video tour of the kit on YouTube:
