I live in the suburbs, I have one am station that I can H-A-R-D-L-Y recieve.

You must be in the suburbs of a desert.
I also live in the suburbs, but of a large city. Good radios (super-het) pickup many AM stations (their sound quality is crap so I don't listen to them) and about 90 FM stations. I also didn't count all the TV stations I can receive (20? 30?) with an antenna.
A crystal radio or a super-regen radio won't work here.
 
I live in the suburbs of a medium-small city. The car radio can pick up about 2 am stations. I can recieve at least 15 fm stations

Then make a super-regen "radio" and let us know how poorly it works.
 
If I make them, I will tell how good or bad the reception is from the superregen and superhet.

Probably the superhet.

You are darn right it is better. By a longshot.
A superhet has many tuned LC circuits to select one station and attenuate the rest of them.
A superhet has automatic-gain-control which goes to max gain for a weak distant station and reduces its gain avoiding overload by a strong local station.
A superhet can be FM-only for superb interference rejection.

A super-regen is simple cheap old junk.
 
You probably won't find radio parts for sale anywhere since radios are inexpensive today so nobody makes only one.
Buy a radio, take it apart and use its parts to make your own radio. Good luck.

I know a site that carrys almost all the components you want and delivers in 2 days. I have 2 identical variable caps but have no idea what its value is; It says CBM-223P on the back. Could someone help?
 
You should just go down to your local dump and trash pick an old radio, why spend any money when you don't need to?

Did you take them out of something?, or did you buy them as surplus?.

Their appearance should give you some clues though!.
 
223p probably means 223 picofarads max capacitance. 365 pF used to be a standard used in AM radios.
 
It's probably nothing to do with the capacitance, it's probably only a part number.

Anyway normally the last digit is the exponant on capcitors, so 105 is 10*10^5 or 1000,000pF or 1uF.
