Hackerhotel 2020: Dustin Snijders -- Amateur TV
Channel: OpenEvents (Conference Livestreams and Recordings)
Date: 18/02/2020

Like all other technology, wireless communication is subject to 
innovation, which translates into digitalization. From a professional 
perspective, virtually no analogue communication takes place.

Digital radio and television (DAB+ and DVBS2), digital communication 
between emergency services, digital telephony both wireless and wired, 
WiFi, Internet of Things, you name it ..




All cable companies and telecom providers almost exclusively provide 
digital services. Even the last analogue television channels that were 
offered via cable have almost disappeared (in Pijnacker only the 3 
public channels left) … The set-top boxes are the last rescue for those 
who do not want to lose their tasty and wild CRT-box.




For radio amateurs, the same thing actually happens, but the 
consequences for these non-commercial activities are always lagging. 
Nevertheless, digital forms of communication are makingtheir appearance 
here too.

During this talk, three applications will be briefly explained. Later 
they can be viewed as a sort of ongoing workshop in the hacker room of 
the Hacker Hotel. Ofcourse you can test and play with it.




Dustin Snijders

Dustin is married, has two nice adolescent daughters and is an employee 
of KPN ICT Consulting as consultant / lead IoT. Part of his work runs 
smoothly into his hobbies. In his spare time he likes to make. 
Electronics, telecom but also 3D printing. Recently also CNC milling.  
Dimitri has also caught

him with the laser virus. As a result, he also started to build his own 
full-color projector. This in turn led to the manufacture of a CNC 
milling machine. Just to be able to mill aluminum parts. Drones and

kites are at a somewhat lower level at the moment. You cannot do everything at the same time…




Workshop




There are three configurations in the hacker room of the hotel deployed:

– Digital communication via the short wave with the help of FT-8 – with 
the help of a short wave transceiver and a laptop, the possibility of 
making wireless connections is created. Experimenting with antennas, 
adjusting antennas and varying transmitting power, supplemented with a 
little patience, is normally crowned with a nice connection to other 
radio amateurs at an exotic location, often thousands of kilometers 
away.




– Sending and receiving digital video via the first geo-stationary 
amateur (television) satellite available for radio amateurs – the QO-100
 (Hailsat-2) satellite can be used for both digital video and 
“old-fashioned” analogue speech. During Hackerhotel, digital video will 
mainly be broadcast and received.




– Experimenting with a Tetra network from Motorola – digital radios, 
still used in the Dutch emergency and security services (C2000), can 
used to play with and do some tests with. Maybe nice to start 
understanding the protocol, helped by an available RTL Software Defined 
Radio stick and laptop? The base station frequency is adjusted by the 
owner. The station now uses the 70 cm amateur band, completely legally. 
This does not change the form of communication and protocol.




The above is legal for the owner of a Full Licensed radio amateur. 
Dustin (PE1OZS), supported by Arjan (PE1MYH), makes his license 
available and will be present during this weekend. Dustin has requested a
 callsign especially for the event: PA6HACK (linked to PE1OZS)
