JFK ARRIVES IN DALLAS, TEXAS, ON NOVEMBER 22, 1963 (RADIO COVERAGE) (WBAP VERSION) 

It’s one of those…if only we could warn them. It was going so well. Then America changed forever.

JFK's Dallas speech would have been broadcast by WFAA, which had 570 after noon when WBAP shifted to 820. The Love Field arrival originated from KLIF, then at 1190 but now at 570.
