Experimentation in mind with this idea. Then later we'll apply the rules.

Has anybody ever fed the 100mW output of a part15 transmitter into a wide-band audio amp (with all high frequency attenuation removed)? Let's pretend it's a 10-watt amplifier.

Play it safe, we're using a dummy load.

Amplifier

I haven't done this but have thought about it on occasion. I talked myself out of it because I know from experience that wide band amplifiers are difficult to keep stable especially when reactive loads are involved.

I am not saying "don't try it" but rather "watch out for instability".
