[NJARC] A slightly off-topic request

[Scott Roberts]

I could always sell you the 39-116RX Philco I have...
Tear it apart and use the remote control receiver and
transmitter- the receiver drives a couple small motors
to change the station... You could adapt that I
imagine. Only problem is, the remote is the size of a
small hatbox! lol
