How the hell was that station interfering? 98.7 is 10.6 MHz from 88.1. The IF frequency of the usual FM tuner is 10.7 MHz. The 98.7 station was WAY more powerful than the 88.1 station, so powerful that some of it was leaking through the IF section.
That’s unusual. Images are usually twice the IF frequency above the tuned station. Some of those early transistor FM tuners had very poor RF performance. I could believe almost any bad tale about those tuners. I’m afraid that we are slipping back to these levels as various Apps and technology licensing deals steal money from the tuner design.
