FM broadcast music, USA FCC range is 88 Mhz. to 108 Mhz. Stereo, and today more than what's called a one channel. Actual frequencies for music probably haven't changed, but lots more broadcast these days with music.
My intent is to test "resistive" biasing of a bipolar amplification system, and I bought an old Realistic Tuner for it's variable tuning capacitor and coil for tuning an RF. And yes I was serious with my "conclusion to an unfinished matter" post and omitting coupling and bypass capacitors. All stabilization is to be done with resistors, WITHOUT capacitors, but sorry I don't have the terminology to explain why.
To kick it harder there's a much better way to test a bipolar amplification system than with a broadcast signal. That's to use the Digital-to-Analog Converter in my phone and route the audio to a homemade amp. using that "resistive" coupling. And please don't ask me why I didn't think of that in the beginning. Because I don't really know if I'm ever going to try building up a discrete tuning and preamp circuit, especially the troubleshooting of one. I'll probably buy an old Realistic amp second hand, and put together an audio amp. And use my phone as the source for music, and test it with my ears. That's my testing method, outside of a good, clean, simple design.
