If you like old radio airchecks from around the United States, do yourself and favor and subscribe to Ellis Feaster's YouTube channel.
Here are two videos he released with some Texas radio audio of the past.
The first is of Charlie Van Dyke's final show on KLIF 1190 Dallas in 1979. Van Dyke went on to become a famous TV voice over talent.
The second video is a November 28, 1956 aircheck from Elliot Field, also on KLIF 1190 Dallas.
These days, you'll find KLIF Dallas on 570AM.
