Okay, sorry for referring to them as "crappy" I didn't mean to be rude.
The major issue with these bugs is finding the right broadcasting frequency with either the bug's trimmer cap or the radio's tuning knob. This is where the advantage of the generator comes in. Because it displays the frequency digitally on a screen, so now the transmission frequency can be exactly determined, and the radio can be tuned to that frequency.
I also kind of want to learn how FM works.
thank you.
