Country has an incredibly bad track record in the broader San Francisco Bay Area (SFBA) market (which runs from Wine Country in the north to Garlic Country way south of Silicon Valley, a span of at least 100 miles). It's been tried on a number of full-market, full-signal stations and failed each time. However, it has done well in the South Bay/San Jose sub-market, specifically in a long run at a lower-power Class A station (KRTY), and up in the North Bay/Santa Rosa sub-market at KFGY.
KRTY's long-time owner died at a ripe old age about 5 years ago, and for estate reasons the station needed to be sold, so it was, to EMF for another K-LOVE repeater. The Country programming and personalities were moved onto the web, which Alpha Media (owner of KBAY) thought gave them a market hole, which they grabbed when they flipped KBAY to "Bay Country" along with a sister station up in Concord in the East Bay. It's been a mediocre performer after an initial burst of interest/listenership.
I recite this history to make the point that there is an audience for Country if a local operator knows where to find it, but if you think that a full-market station is going to ignore history and flip their station "to compete with Bay Country", you don't know the market. (And it so happens that any audience for Country in the immediate San Francisco/Oakland area can likely pick up one of the two stations I mentioned above on their car radio, so it's not like they have *no* country options. I'm halfway down the Peninsula and can receive both on a table radio.)
KFGY anywhere south of even Marin is very; very impressive: https://www.rabbitears.info/contour.php?appid=34074a63e69140788529c1b6063ebeb7&map=Y
KBAY has a much better signal though, yes. Agreed there.
