That is what Facebook and other social media apps are for.
Most of the people I knew are of the age [probably about 5-10 years older then I am] that they don't use Social Media Apps [a few do and I have reconnected with them after several decades] a few remember me, a lot didn't since I was only there for a few months and the station was failing and everyone was in an "abandon ship, every man for himself" mode. Since I USED to be an avid DXer [What's the point anymore since most stations are running the same syndicated crap?] I actually called some of them....I remember a couple of them after playing a Paul Davis song wondering if he was still alive [after 2008, when he died] and they were from some station in NC or SC, can't remember exactly, and it blew their minds that I called them and I was listening to them from Ohio. And same for a DJ late one night back in the early 80s from WTMJ that sounded like he was bored and wondered how far away was that anyone was listening to him. I called and apparently I was the only one that had called. I ended up talking with him for a couple of hours. I was actually trying to pick up WSUN out of Saint Petersburg, which is what I used to listen to growing up there along with WLCY, and since WTMJ/WSUN were both on 620 they were fading in and out over each other.
