Short form:
- QMX ordered
- waited ( waited, waited, waited patiently)
- built, => firmware installed, => turned on, => running.
Once again confirmed, the kits from QRPlabs are great.
To fit so much RF technology into such a small space is quite a challenge.
Even for the experienced solderer.
But it is exactly as described in the assembly instructions in many places: Read carefully, some things twice, look closely with a magnifying glass, and take your time.
I took my time, but nevertheless I was done with the soldering after about 15 hours.
The installation of the firmware is really very simple. I only had to get a USB C cable.
7 Volt, 250 mA, take a deep breath and....
no smoke, no smell, everything wonderful, the little wonder box is running.
Antenna on and immediately signals on the 40m band.
Now the installation in the enclosure takes place.
Fine thing.
