Tuned in to hear the very tail end of
"...PAPA on frequency eight thousand...how copy? over"
I know that the frequency 8000 kHz is part of the larger 7300 kHz to 8195 kHz fixed/mobile allocation (yes, I know the lower portion is heavily used by broadcasting and other things and 8000 kHz to 8195 kHz is a shared allocation with maritime mobile / marine mobile radio service - usually simplex operations...)
Could have been a marine operator? Sounded very professional, more like military or similar. Have been sitting on frequency for 5 minutes or so and haven't heard a peep after the "how copy? over." transmission
