The Minitiouner receiver V2.0<\/h1>\n

Because I liked the concept, I started building the DATV MiniTiouner receiver with PCB’s from the British Amateur Television Club (BATC).
\nThe receiver consists of a (very good) wide band tuner from 140-2400 MHz, including the 2 meters and 13 centimeter band.<\/p>\n

The tuner is built together with the other components on a motherboard controlled by USB and the Minitiouner software.
\nI have added an extra OLED screen on which the settings of the tuner are indicated. This is already prepared in the software.<\/p>\n

The results where very good. I received PE1ASH directly on 23 and 13 cm.<\/p>\n

After completing the Minitiouner project,\u00a0 I started building in 2019 the Portsdown DATV transmitter. This was a hard job, especially the modulator PCB with it’s very small IC’s. But it came to a good end and the Portsdown worked perfectly. I made quite a few DATV QSO’s with it!
\nUnfortunately, the mode was 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……<\/p>\n

……. and this future came in 2026…\u00a0 I start building the Portsdown 4 based on the RPi-4 and the Pluto SDR module from Analog Devices.\u00a0 Not the LimeSDR, because that was too expensive ☹️<\/p>\n

After purchasing the necessary hardware, construction could begin. The housing also had to be modified due to the larger display. Once everything had been modified and installed, testing could begin. Loading the software went smoothly, including the necessary updates and the software for the Langstone Narrow Band Transceiver.<\/span><\/p>\n

Fortunately, everything worked 100% immediately, and switching to the Langstone software was also straightforward.<\/p>\n
