-We want to encourage you to play around with radio waves through the use of SDR. If you have never used SDR before, it's a great chance to get started - it's easier than many people think. In our challenges you will have to decode certain messages in various modulations and read out the challenge flags. In the Bluetooth Low Energy challenges you will have to open various BTLE locks by either applying a known attack or sniffing codes from the air.+We want to encourage you to play around with radio waves through the use of SDR.

 There will be a scoreboard to measure your success against other participants with prices for the top players. If this is your first time playing with SDR we will give you a small price if you make it onto the scoreboard at all.  There will be a scoreboard to measure your success against other participants with prices for the top players.

 +You will need an SDR. We are unfortunately currently out of RTL-SDRs - if you want to participate, you need to bring one or lend it from someone.
  
-You will need an SDR. For those who do not have an SDR we have RTL-SDR devices that you can borrow (for a small deposit) at our assembly. +You will need a Computer with some SDR software. A good starting point is to have GNURadio, gqrx and Inspectrum installed. Or any other software that you are already familiar with.
