Hi All, I’m happy to have a new public version available for OpenTuner. This version had a focus on improving various stability and performance issues while adding some quality of life features. This doesn’t mean its a boring update though with some fun new additions added as well 😉 Apart from the usual bug fixes…

PicoTuner – An Experimental Dual TS Alternative
Colin (G4EML) has recently been working on a great new project. Its a Raspberry Pico USB interface alternative for the FTDI FT2232H module. This module is fairly expensive and difficult to get in some countries so this is a welcome project. This project also supports dual TS reception with the advantage that you only need…
In The Shack – 2024 – Week 3
Hi Everybody, I tend to usually only post if I have a new version of software ready for testing, or completed a specific project. Unfortunately this leads to long times before posts and then I get emails asking whether I’m still alive :p I’ve decided to start a weekly post or so just chatting about…
QO100 DATV Decoding with SDRangel and SDR
Introduction SDRangel recently had an update (v7.8.1) with a couple of enhancements and fixes. One of the updates was an addition of adding a dial to flip through DATV standard symbol rates. It’s not a big change, but it has inspired me to download it and try to decode some DATV transmissions from QO-100. Being…
PlutoSDR on Network via Raspberry PI
I’ve been playing recently with the QO-100 high speed modem, its been working well, but one of the smaller issues I’ve been having is that every now and again I get bad packets. I’ve been tweaking all kinds of settings on my SDR Console as per the documentation and while I receive most packets it…
Practical DATV Network/Internet Streaming Experiments – Part 1
Background Whenever you deal with media be it audio or video, streaming it over a network or the internet always comes up. The amateur radio television hobby is no different. We are creating content that is being transmitted over various platforms including satellites. The QO-100 satellites has also opened up these kind of experiments for…
QO-100 Dish Calibration Using Longmynd
Setting up your dish for QO-100 is always a fun challenge, especially if you are using it for the Wide Band transponder on QO-100. Larger dishes are more difficult to fine tune. I’ve been thinking about building the functionality into the Android Longmynd Client, but there is still a bit more work to be done…
Offline Oscar 100 Wideband Spectrum Monitor with SDR
If you have been playing with DATV on the Oscar 100 satellite, then hopefully you know all about the online Wideband Spectrum Monitor provided by the BATC. Its bad form to transmit without keeping an eye on the spectrum because you could be transmitting over someone else. But what if your internet is down, or…
Adalm Pluto Rev C/D Configuration for DATV
I recently got a new Adalm Pluto (PlutoSDR) which I wanted to setup for DATV transmissions on the Oscar 100 Satellite. Its the new revision C/D (It says revision C on the Box, but shows revision D on the circuit board). Its been a while since I’ve setup my previous one which was an older…
Oscar 100 Wideband Spectrum Clock
I needed a clock for the shack and it seemed fitting to put something fun together. Since I’ve been busy playing with DATV on the Oscar 100 Satellite, I figured a clock that would also show the wideband spectrum activity would fit nicely. The spectrum data for the clock comes from the BATC Wideband Spectrum…
