Construction

Radios

Many different ones, some COTS, some home-made

Existing radios have been small and simple

They’ve also been slow (e.g. Libertad-1 at 300bps with AX-25) or power-hungry (MHX series receive idle current @ 115mA)

This is an unfinished / unresolved area of concern for the CubeSat community.

Bands / Frequencies

Primarily amateur due to licensing restrictions: 144MHz, 433MHz, 920MHz, 2.4GHz

Antennas

Patch (GeneSat), x4 (Delfi-C3), stubby (MAST), tape measure (CPn), genetic algorithms (NASA ARC)

Omni required if no attitude control. With ADAC, can improve antenna gain
