Answer 1

it looks good cept you might need to switch around your ant and ground because it looks like nothing would get into the base of the transistor because of the grounds placement but I not sure, looks pretty tight though...

Answer 2

Your 9V supply is turning the transistor on, then discharging through the transistor to the negative side of the 9V supply, and also through the inductor to ground. What is that dial looking thing, next to the pitiful drawing of a speaker? At any rate, this circuit will not work. Try looking up AM receivers, if that's what you want to build.

Answer 3

Remove the connection from the LC tank circuit, between the antenna side and collector.
Unground the base.
Ant and earth, to tank, would be ok.
Add a detector diode from ant side of tank to a small coupling capacitor, then to base of transistor.
Connect low ( +)side of battery and emitter to ground along with low side of tank.
Add an appropriate bias resistor from ( -) battery to base, to supply forward bias current to permit linear operation of transistor. ( Class A ).
Gain will be insufficient to drive a speaker.
Add an appropriate load resistor from bat (-) to collector.
Add a small value electrolytic cap from the collector and connect in series with a crystal ear piece and then to ground.
Remove speaker and rheostat.
There won't be an excessive volume problem.
Only local strong AM signals will come thru this.

Answer 4

No, it won't work.

There is a d.c. short from collector to base through L1.

I don't have time (or much inclination) to design one for you but search through Google for "simple radios" or "simple radio receivers".
