fm radio gear

[Alex... (GKD)]

recently got a big box of free stuff from a guy who used to do helicopters and with in this were four transmitters.

all are FM and different makes

My question is, does anyone use FM and if so what are the rules and regs on this,


 I shant be using them for a car as there all 4 way with various switches for the choppers (idle and other such things)

cheers alex

This most people know, or need to:
27MHz - All radios, including broadcasting
40MHz - Surface Only
35Mhz - Aircraft Only

27MHz and 40MHz are normally AM (Amplitude moderation)
35MHz is normally FM (frequency Moderation)
Futaba started using 40MHz FM for their "Synthesized" Radio setups, which effectively does the same job as 2.4GHz, however they weren't quick enough to get it on sale, and 2.4GHz took over. They were also doing the same for 35MHz, but again, never really took off.

Nowadays, the only 40MHz FM systems are basic 4-channel, possibly 6, but for things like Tamiya Tanks, Lorries or maybe robots

Any other questions, please ask
