hi,
Im creating a VHF receiver, i need to build an oscillator that will resonate at 136 Mhz. I'm planning on using a crytal and overtone it but i believe i need to buy a crystal that has already been overtoned, but i cannnot find a 136 Mhz crystal. Is there any way i can create an overtone crystal using a fundamental crystal oscillating at 19.4Mhz and overtone it to 7th overtone. Could you guys give me some ideas.
