Hi guys, I'm looking for a data sheet and schematic for two types of IC's one of them is used in a transmitter, like an rc remote control and it's part number is SCTX-2 9H012 and another one is used in a receiver i'm not sure of it's part number but i believe it's RX-2 9H018. also if any one can send me a website where I can search for ic's specially made for transmitters and receivers, or if someone could suggest some ic's. It would help me a great deal. Also I'm trying to design a transmitter, receiver system using FM, so if you guys can send me a circuit suggestions and one last thing, what do we mean when we say that a transmitter has 4 "channels" the word channel is confusing me if i know it correctly I think it simply means 4 "frequencies" so please send me the concept behind this. I'll stop right here 'cuz i've asked a lot but any kind of help would help me out a great great deal. Thank you very much!
