Used it for my last three activations. This time with an experimental amplifier for a pretty rewarding experience.

Thought I would post mine…here operating on 0.25W powered directly from a USB powerbank at 5V.

For any new owners …be sure to calibrate the frequency, mine was around 0.5kHz off.

Hello,

here another new user of this toy; pictured aside the tiny BaMaKey and a pen; I can’t believe it’s that small!

Today I chased a couple SOTA from home with it, after repairing my kit from the transistor blown …
Looking forward for its first activation soon.

My order on eBay (hison-818) from 31. May 2022 for (tr)uSDX (assembled with case) and ATU10 arrived today! It is working out of the box. Powered from USB port on my home computer it delivers 0.5 Watts output power - with this power I managed to chased OK8CX/P on CW and IW2OBX/P on 40 m SSB, both on my first call! Amazing.
Will see tomorrow how it delivers with 12 V battery.

Best 73,

I’ve had one for a few weeks, but didn’t get around to doing a SOTA activation until last weekend where I used mine to make 3 20mSSB contacts on w4v/sh-016. One of those was F4WBN, which surprised me because I was only putting out about 4w.

Antenna is a coil-loaded EFHW 40/20/10 (only 40/20 usable on the Tr(uSDX)). The whole thing, radio, antenna, battery, and earbud weigh in at .85lb.
