What piece of hardware am I looking for to observe the transmitted radio signal? Would an oscilloscope come in handy here? is this a 2-channel RF remote, a 3channel RF remote, or something else?
My goal is to build my own circuit that emulates this circuit. Would I require a bus pirate for this? I realize it might be much easier just to buy a new remote but I'm using it as a learning experience rather than a cost saving endeavor.
googling the IC, a message board mentions its probably a custom IC. The IC has the following printed on it: 0412 SEMEFAB 051-8728 0821-D (LF) D[big letters, on right]
