Did dah have cb radio too?
Respectfully snipped.
I am wondering how much "CB" radio plays into this. 1989 was the peak year of very disruptive sunspot activity that made CB radio all but useless as a communications tool.
Not sure if it means anything or not. Another peak was in 1991. This interference lead to a heavy decline in CB use with most folks switching to GMRS or 10 meter.
