Hi, I am trying to recreate a remote for a very old toy. The current remote is broken and not working due to its age (1980's).

From my understanding it uses a 27.145MHz crystal to talk to the receiver, I did a test with a newer 4 channel 27MHz controller and the toy responded to the forward control.

I have know very little about electronics and would have no idea how to create a schematic for a simple 1 channel transmitter that uses a 27MHz crystal to replace the board in the old remote.

Any help would be greatly appreciated!!!

Cheers

Thought about fixing the old one....?
Other than that there are many keyfob remotes available but on the 400 or 900 mhz ...only a couple of dollars for complete setup....would need to convert the relay output to something usable though ....
What does the existing system consist of and how does it control the model..?
