Hi all!
I'm not sure that a new topic was necessary (if not, please correct this and let me know...).
I have "a problem" with RF key of my car...
It works only about 5-7 meters around the car (the battery is OK) and I want to buy/build a car alarm which will use as a remote control the RF car key.
So, I need to increase the distance of transmitter action (I made some tests and I'm sure that the transmitter is to poor and the receiver is OK).
The RF schematic/photo of the TX attached.
Thank you!
