While I have not confirmed this by hearing a station ID, I do believe I have the only Radio Disney west of the Mississippi on the frequency of 1290.
Several times in the morning on my way to work, I have tuned to 1290 and heard faint radio Disney commercials and people saying your listening to Radio Disney. That station is 1290 KKDD, San Bernardino, CA Radio Disney. Once again, i didn't hear an ID but I don't know what other Station this could be.
