RE: JR 6102 Questions
(b) An R/C transmitter which incorporates plug-in frequency
determining modules which are changed by the user must be certificated
with the modules. Each module must contain all of the frequency
determining circuitry including the oscillator. Plug-in crystals are not
considered modules and must not be accessible to the user.
Does this mean JR tx are in violation of federal law since the crystal is right there on the back accessible to the user?
where are Futaba crystals located ?
