KBSO

KBSO carried a "Texas Mix" format consisting of outlaw/progressive/classic country along with some rock from artists like ZZ Top, Stevie Ray Vaughan and Van Morrison. They were on the air from 2001 to 2006. After switching to Tejano they have since returned for one more go at the Texas Country format as "Badlands FM." KBSO is licensed to Corpus Christi, Texas.

KRYS

Not sure what the format was for KRYS-AM but the current KRYS-FM in Corpus Christi, Texas is Country so there's a good chance the AM was as well. It was a Radio Disney outlet long after this sticker was printed which has a 1970s look to it. 1360 AM is now KKTX, a News/Talk station.

EDIT:  15 years after originally posting this I received a KRYS music survey in the form of a 45 rpm record sleeve.  The chart confirms what many have already said in the comments, that KRYS was a Pop/Top-40 station...at least in 1978.
