Because I liked the concept, I started building the DATV MiniTiouner receiver with PCB’s from the British Amateur Television Club (BATC).
The receiver consists of a (very good) wide band tuner from 140-2400 MHz, including the 2 meters and 13 centimeter band.
The tuner is built together with the other components on a motherboard controlled by USB and the Minitiouner software.
I have added an extra OLED screen on which the settings of the tuner are indicated. This is already prepared in the software.

The results where very good. I received PE1ASH directly on 23 and 13 cm.

The Portsdown transmitter

After completing the Minitiouner project, I started building the Portsdown DATV transmitter. This was a hard job, especially the modulator PCB with it’s very small IC’s.
Unfortunately, the mode is DVB-S while now more and more hams are going to work with DVB-S2. Maybe I replace in the future the modulator of the Portsdown by a LimeSDR….
