I have an old Graupner 35Mhz transmitter and receiver which I would like to get running again. Bought batteries and connected power and a servo to the receiver but nothing happens when I use the transmitter. Both have the same frequency quartz.
Do you have any tips on how to verify that both the transmitter and the receiver are functional or how to debug? I have a basic oscilloscope and a multimeter at hands. Both batteries are loaded and connected properly, I think. When I connect the servo to the receiver I sometimes get a tiny movement of the servo as I am plugging it in.
Any helpful input would be highly appreciated
