Happened to fall across this article published in December titled "FM In Liminal Space". It's about LPFM stations and the value of community radio and so forth, but what caught my attention was it's brief mention of a part 15 AM station we've talked about here in the past:

"..... This isn’t Collinsville’s first rodeo with radio. About 15 or so years ago, a gentleman used to set up a hobbyist Part 15 station on 1620 KHz. AM in the parking lot of the canoe rental place on the weekends. It was a sporadic operation that despite its excellent engineering was still limited in range by the restrictions placed on it by license-free operation....."
I knew what he was talking about and just had to dig it up again. I've always found this Part 15 AM pickup truck station interesting. The Herald Courant did a story on it back in 2007 ( https//www.courant.com/2007/01/25/radio-collinsville/ ) it's a fun read, and the Hartford Radio History website used to feature a pictorial story on it but apparently took it down at some point, but it is still available on the Internet Archive: RADIO COLLINSVILLE https://web.archive.org/web/20111007212832/https://hartfordradiohistory.com/Radio_Collinsville.html
I'm wondering two things, one, what kind of transmitter is that? A homebuilt unit I'm guessing but what I find peculiar is that there's no cover on it, it looks exposed. The guy that took the pictures said he didn't see the owner of the truck around, so it's not like they took the cover off for the photo shoot or something. He also had an interesting grounding system that I've found peculiar. I wonder what of ever became of that part 15 pickup station. I recall something about another part 15 station in a van.. can't seem to recall where that one was right now.
