AAUSAT3 emit two types of messages

1) Messages for which you need special decoding SW (and HW)

2) Old fashion morse/CW beacons.

It is 2) you can receive if you have an radio that can recieve around 437.425 MHz.

So you can record the morse/CW beacon
from the audio/headphone output on the radio.

We use audacity (program) for editing sound and the beacon you see on the hoempage is just a screen snapshot from audacity. So I think hand decoding is possible :-)
You can download orbitron(windows) or gpredict(linux) and select AAUSAT3 in cubesats. It can predict/calculate when you will be able to see AAUSAT3 meaning direction(azimuth) and elevation. So having a watch, a compass and a handheld antenna you should be able to point at AAUSAT3 and receive beacon.
Doppler:

Due to the 7.5km/Sec velocity there is doopler shift on the radio. AAUSAT3 is on 437.425 MHz but when comming over the horizon you should increase freq on radio with approx 12 kHz. 0KHz when above your head and subtract 12 kHz just before leaving behind the horizon. It is not so critical but many radios has a input filter with width approx 15 kHz so you see it is better to correct a little

We are working hard on our Blue Box ground station. It is a small - with USB interface - radio for receiving communication from AAUSAT3. It is based on the same ADF radio chip as AAUSAT3.

It is our humble intention to give it away to people who will help us listening to AAUSAT3.
