Am - FM
If I have understood correctly, most people equate the AM and FM R/C signals with our regular audio AM and FM signals for our car and homes. But my understanding is the FM and AM signal for R/C is not the same as that used for Stereos, The industry has labeled them this way because AM for public broadcast is a single wave and AM for R/C is a single wave , FM for broadcast has two waves (stereo) and FM for R/C has two waves, and that is the main reason the R/C has been given the AM or FM designation, The actual signal of a R/C AM and FM is not that different and nothing like the broadcast AM and FM. It has always been known that a AM Can interfere with an FM of the same frequency and FM with AM similar to FM and FM/PCM. The fact is AM radios are just as reliable as FM if properly tuned , back before narrow band it was not always the case because of inaccurate tuning .
