Al Skierkiewicz has a reputation beyond repute

I am interested in this as well. The inteface to the radio modem is RS422, which uses a "balanced" wire pair for both transmit and receive. This serial protocol was developed for high speed data transfer with good noise immunity. The PWM cables do radiate though, so I am interested in a full assessment.
Teams have reported problems with radios in the past and many of them are due to common problems with mounting the modem. i.e. mounting deep inside the robot, antenna mounted against metal(especially the end of the antenna) broken wires in the serial cable and pinched or crimped wires at either connector.
Good Luck
