I’m always intrigued when some former owner leaves his handiwork or mark on radio gear from the past. I recently came across the HRO receiver coil and caught my eye how much effort the previous user had put into making up a logging scale for the set. He must have been an avid listener to have taken the time to create such. I imagine that one could go back through the station list and get a pretty good idea of the year and even location of the previous owner.
