KPYN is a radio station airing a News-Talk format licensed to Atlanta, Texas, broadcasting on 900 kHz AM.

The station was first licensed in 1950, as KALT, to the Ark-La-Tex Broadcasting Company, operating with 1,000 watts on 900 kHz, daytime only.

On March 17, 1997 the Federal Communications Commission (FCC) announced that 88 stations had been given permission to move to newly available "Expanded Band" transmitting frequencies, from 1610 to 1700 kHz.

KALT was the only station in the United States authorized for 1610 kHz.

The FCC provided that both the original station and its expanded band counterpart could optionally operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses, depending on whether they preferred the new assignment or elected to remain on the original frequency.
