Hi,
I saw another post about multiple frequency FM transmission but it was a bit different. I'm looking to design a simple circuit modifying a single-frequency FM transmitter to 3-4 different frequencies.
Assuming I already have a signal at say, 100MHz, from what I understand I need to create a few other signals to multiply with it; e.g, at 1,3,5 MHz. I'm a bit confused about how to generate these signals. I've been told to use a crystal oscillator, but It's such a huge scope that I don't know where to start.
Basically I'm wondering how to get started on making these other sine signals. Any help would be appreciated.
