One could argue that an electronic device that converts a non-electronic signal is an electronic device. However, that would mean the Driver Station is an Electronic Device because it receives communications from the robot, which is outside the Castle. Or if there is a student that wears a hearing aid ...

G29 During a MATCH, DRIVE TEAMS may not use electronic devices which have the capability of receiving communications from persons outside of the CASTLE (e.g. cell phones or wearable
technology). Violation: YELLOW CARD

Also, it never states that the drive teams can't use electronic devices which have the capability of sending communications outside of the castle.

So I'm saying...maybe as an example: The drive team has a wireless transmitter that is connected to a wireless receiver that the spy has.
This will only work if it's a receiver that is only able to receive communication from a single paired device, the one in the castle, or else it would have capabilities of receiving communications from people outside of the castle.
I don't know any 1-on-1 transmitter - receiver systems by name, or where you'd get them, but if you do, they're in compliance with the rule.
The drive team in the castle is only receiving communication via non-electronic methods from the spy, and the spy is only receiving information from the drive team within the castle.
