I checked 1590 kHz, at 2025 UTC, and "NewsPlus 1590", WZRX, Jackson MS, is again broadcasting a test tone. Expect to hear ABC News on the hour.
Their schedule shows they should be carrying the "Phil Valentine Show" to 0200-0600 UTC.
They were heard earlier broadcasting a Southern Mississippi University baseball game.
