AAUSAT4 transmits CSP packets encapsulated in a custom spacelink framing format. The radio subsystem works as a router, where subsystems communicate directly with the ground station server.

The spacelink frames start with a variable length training sequence (default 60 bytes 010101010....), followed by a 6 byte syncword ("OZ4CUB"). The packet format supports two different packet lengths, either 25 or 86 bytes. A one byte Frame Size Marker (FSM) is used to differentiate between long and short packets. The FSM is 0xA6 for short frames and 0x59 for long frames.

Frequency: 437.425 MHz
Frequency deviation: 9.6 kHz
Modulation Scheme: Gaussian 2FSK (BT=0.5)
Bitrate: 1200 to 19200 bps (default 2400 bps)
Callsign: OZ4CUB
Forward Error Correction:
Inner code: Rate 1/2, k=7 convolutional code
Outer code: (255,223) Reed-Solomon code.
