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…

QO-100 High Speed Modem and Weather Station
Overview If you have been active on QO-100 then you would by now know about the High Speed Multi Media Beacon. The beacon sends high speed data within the maximum allowed bandwidth of 2.7 kHz. I’ve previously done a post on development information as well as some tips and tricks to get it going on…
QO-100 High Speed Modem – Info/Tips/Development
The QO-100 High Speed Modem is a very exciting development from Amsat-DL and DJ0ABR. The modem itself allows for sending all kinds of different data including files, images and even experimental voice. The QO-100 Narrowband Transponder has a multimedia beacon currently running where you can receive and decode lots of interesting information using the High…
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…
Networked DATV Receiver Experiments
I have been having some fun playing with DATV on Oscar 100 lately. As DATV isn’t really a thing in South Africa the satellite has given me the opportunity to get a bit more involved in the DATV scene. If you are interested in DATV then the BATC should definitely be your first stop on…
