First spotted by several on the #pirateradio IRC channel, we have some USB comms in American English on 6906.1 (approximate) USB mode that sound like they could be a US military exercise. Tracking simulation with callsigns including TORINO, CORVETTE, KILO, HELLCAT 53, WOODPECKER, VOLCANO, CITY HALL and perhaps others. Speculation on #wunclub is this could be USS GEORGE H.W. BUSH (CVN 77) training/testing activity off of Florida. Thanks to mco, N2UHC and Token for help.
