I had posted about this a couple years ago but never followed through because I found a source of more transmitters for the frequency I was looking for. Now I'm in need of having to convert again.
I mapped out the markings on the components of the 433 vs 315 board and found all these differences. Some of markings on the little beige components are too difficult to read, so I'm missing 3 parts. The 315 board is also missing the SAW resonator because I had tried soldering in a 433 MHz resonator and that alone didn't work.
Do the experts think I really need to swap this many components to make this work, or are there obvious ones to try first. Thanks much!
