SDR recording catch.
Signed on 6880 AM at 2313 UTC.
Off at 2330, then on 6905 and 6950 briefly with carriers but no music. Then over to 6943 at 2334 UTC. A good signal until 2342 or so, then it faded out. Then shot up to S9+20 around 0006 UTC.
A fairly decent correlation between signal strength and the Wallops Island foF2 plot:
