    Actually, you are quite lucky with SDR, as there are many such stations on the Internet where you can tune in locally at that location and listen as if you are there. I operate one for listening to our local ham radio frequencies on VHF at https://openwebrx.gadgeteerza.co.za. But mine is very simple compared to some of the more complex one’s available.
