hello, new member so i'll start with a simple question. is there a circuit i can buy to boost the signal of a small pocket radio. i work in a building where the signal disappears and i cant hear anything and i was wondering if i could buy a circuit to attach to the pocket radio to boost signal. it works as i get closer to the doors or windows, it a little bit annoying! i would be very grateful for any ideas and in the process help make my monotonous job a little bit more interesting, thanks,p
