Not much info on Scotland in the RRDB. I would suggest searching for a local enthusiast group via Google or on YouTube to start. You could also purchase a RTL-SDR and download SDR Sharp (or similar software) to scan the radio spectrum for active frequencies. It can be a complex subject, and a little daunting for beginners.
Sorry for a general answer to a broad question.
