I'm building my first radio receiver (a simple Ramsey HR-40 kit). The "Alignment" section of the instructions requires that I have some other device which I tune my receiver to. Since I have no such device I plan on buying one. The cheapest option seems to be a crystal oscillator. However, how I would use this crystal oscillator to tune the receiver isn't very clear.
I'm assuming I would want a crystal oscillator in the appropriate range (for me a 7.2MHz one should be good). But I'm not sure what I'll need to do with it and what additional parts I'll need. Will the oscillator actually emit a signal that can be picked up by the receiver? Or do I actually need to add the oscillator to the circuit somehow? And what other circuitry will I need to drive the oscillator? Thanks!
