I'd get a part 15 AM transmitter and broadcast your own material. Your 37-116 has a much wider band width than radios do today. This will not help you when listening to broadcast stations using your 37-116 but if you get a SSTran AMT3000 AM transmitter it has a wide band width so the material you broadcast will have much improved frequency response. SSTran claims 20-20k response though I doubt it is that good. My father has a 37-690 and I built him a AMT3000 and the sound is very good not stereo but as good as mono gets.
