They were founded by loonbag crazies
You might disagree with them, but that's not true. When they began, Pacifica stations were among the highest of the highbrow stations, with articulate talk and serious classical music. That continued until the early 90s. Then they went stone cold nuts.
How about a frequency swap with KPCC and some cash? KPCC sure does more with its 600 watts than KPFK with 100,000 watts!
You need to read the letter in the OP. They will not sell or swap under any condition. The Foundation is doing everything it can to keep these stations operating, and they're fighting against the people at the stations. Anyone who suggests selling or swapping stations is seen as the enemy. It's not going to happen.
I think KPFK should go silent over the air. 90.7 at 100k watts is much better put to use for a real public radio station and the KPFK people should just be doing podcasts
They're doing both. They know they own beachfront property, and they're not moving.
