Having grown up in Texas and Oklahoma and having spent a significant portion of my youth in and around Tulsa, I'm quite familiar with the area. My dad's family has strong ties to Pittsburg.
When it comes to what carries reliably, how many signals besides 106.1 and 107.5 could the average home in Parsons get? Both of those have towers north of the Tulsa metro. My parents were adamant about not paying for cable when we could watch TV for free. So, we had an outdoor antenna for TV that we also connected to the home stereos in our house in Midtown Tulsa. I could consistently get multiple FM's from OKC and Ft. Smith as well as a few from Wichita and even two from Springfield, MO. KLTY 94.1 and KDGE 94.5 from Dallas reliably came in on the digital home stereo until a move-in and a semi-local rural Class A signed on right on top of them. My friends' home stereos couldn't do that, and the only distant stations that were reliable on the average digital car stereo were KEBC 94.7, KLTE/KOQL 101.9, and KWKL/KYQQ 106.5. The last of those mentioned even occasionally showed up in the Tulsa Arbs, though most of its listeners were probably northwest of town in Osage County. People who lived in far east Tulsa and around Broken Arrow could get KISR 93.7 from Ft. Smith on good radios (and it even had a translator in Broken Arrow for a brief time in the 80's), but, living about a mile from the Fairgrounds, 106.1's translator on 93.5 obliterated everything on 93.3 and 93.7 at the house. None of those signals I could get 30-35 years ago have been consistently listenable, even on the best radios, in and around Tulsa for at least the last 10 years. Two translators on 94.5 and 94.9 make what's now KREF-FM difficult-to-impossible to receive, and all the other stations I could consistently get either now have translators on top of them or new signals on or adjacent to them.
Smaller cities and rural areas might have a little better luck, but even the upgrades and new stations since 1990 impact many of them. I doubt you have as many options in Parsons today as you had years ago. The dial in Southeast Kansas has shifted a lot since the late-80's/early-90's, both to accommodate upgrades in adjacent bigger markets and to upgrade their own signals.
