TI LM386
(OP)
I was working on trying to use this amplifier for a small radio. I copied the design from the datasheet with a gain of 50. Has anyone ever utilized it for a radio? Were there any problems? Have anyone tried powering it with a small 6V solar panel?

It's a very common little audio amplifier. Widely used in such projects.

Voice is a no-brainer, since the bandwidth is low and distortion is a fact of life.
Music would be tolerable for most people, but those with "refined" ears would probably squawk.

RE: TI LM386
Just to be clear, the LM386 is an audio amplifier good up to near 100kHz. To amplify cell phone signals you need an RF amplifier good at a couple GHz. Not only are there four order of magnitude difference between these frequency ranges, there are about four order of magnitude difference in design knowledge needed as well.

You better read some serious text-books on RF before spoiling your youth on projects like that.
I am kind and extremely lenient when I say so.

You had better start from square one and explain what you're trying to accomplish, because not only are you on the wrong road to project success, I think your road is in a different country altogether.

That's what I meant. Thanks, but I already have. Don't worry I haven't spoiled my youth.
Understood. The frequency was what I was trying to find out. Proceeding to end. I appreciate the insult, I'm done with this board.
