The best case scenario for FM radio (when you would finally find something that you could tolerate) was 1 hour. 1 hour of variety to stave off bordem and try to save your sanity. The effective range of the FM signal bubble was around 75 miles/120km. If you were unlucky 'Seek/Scan' button would be broken on the radio. Most radios in company supplied trucks were very shitty.
MY favorite times would be at night and manually adjusting the AM reception and picking up stations from all over the world. Trying to discern their location based on the commercials.
Sat. radio offered me consistency. It was wholly replaced once I discovered that audiobooks could be downloaded (and not cumbersome audio-cassettes).
Then as the years passed the variety on the stations offered diminished to the point that it seemed like they were playing the same 5-6 over & over again.
Mergers happened. Personal audio players got better. I could download enough books to keep me entertained for a month AND have music playlists that saved my sanity.
So I cancelled.
I STILL miss 'Spa Radio' channel73(?) when I am driving in hectic or tense traffic. That always enhanced my calm.
