I thought this topic fit in with all the other ones that go against the grain.
WVIA in Scranton (Pittston to be specific), back in the '80s and early '90s, used to air a lot of non-PBS fare. Reruns of Leave it to Beaver, the Honeymooners, I Love Lucy, All in the Family, and even Dark Shadows.
There was a time they had "Star Trek" marathons on Saturday nights. Any other PBS stations doing or did this?
WVIA/44 also played a lot of Creature Features on Saturday nights back in the 80's. I picked them up frequently during summer trops (when local WGBX/44 in Boston would be off the air overnights). It was a very unique PBS station.
But also, today, KBYU-TV (Channel 11, Provo, UT/PBS) carries reruns of
"Perry Mason",
"I Love Lucy",
"My Three Sons",
"The Brady Bunch" and yes.....
"Hogan's Heroes" on a regular basis. Last time I was in the SLC area I was quite surprised and pleased to see such unusual fare on a PBS affiliate. It must be good for them come pledge time! (But then again, the LDS (Mormon) Church owns them as well as Bonneville's KSL-TV (Channel 5)).
The old WQEX/16 (Pittsburgh) also ran a unique sked of mainstream programs as well in the 80's and early 90's. It had quite the following, more so than the mothership station WQED/13. But, 'QED quickly put 16 as a simulcast with 13 and sold it a few years ago after a few years of home shopping stuff. (16 had always had a commercial license, but ran it non-commercially)
Also, the old
New Jersey Network used to run
"Dark Shadows" as well, back in the 80's. Jonathan Frid ("Barnabas Collins") used to do the pitches for NJN. (Some of Mr. Frid's NJN pledge breaks can be seen on YouTube!)
