The old business card below made it’s way to me recently.
Notice the five digit telephone numbers.
The radio station transmitted at the 690 megahertz frequency. KEPO was an ABC affiliate. The frequency was later used by KHEY and is now used by KTSM.
This article shed some light on the subject for me.
If you have items like this please send them in to me for publication.
