I’m wanting to first build a transmitter for 108kHz (later a reciever). I started by asking for a quote from a company for a custom made 108kHz crystal. Now they meantion that I need to give them the “load capacitance” before they cut it. So in one single request, I’ve already gotten way over my head - I’ve no idea what to do now. I don’t know what they’re talking about, or what numbers I can give without actually having a TX curcuit design in mind. Searching 108kHz on google brings up nothing about actually transmitting/recieving on that frequency... is there anyone here who could help me design these?
