I prefer to use my own radio. How can I integrate it into the CubeSat Kit?
The simplest approach is probably to package your radio in the same form as the MHX transceiver, so that it can be plugged into the MHX transceiver sockets. You can then choose to control the radio from the Flight MCU, or externally via the CubeSat System Bus. Note that the MHX transceiver socket is supplied with +5V power from +5V_SW.
