Triode Regenerative Receiver Circuit - room for improvement and possible errors
I certainly don't have enough experience with radio circuits to say much here, but one problem sticks out to me immediately: your potentiometer R2 doesn't have its third terminal connected. Since turning a pot (or sliding, if it's a slide pot) can cause the wiper to bounce up off the track, it's usually recommended to connect the "unused" terminal to the wiper to prevent internal arcing when turning it, especially with an inductor on the other side of it.
