I have what sounds like two beacons near that freq.
Beacon 1 is a short dasher, center frequency was about 8193.7 kHz and rising at 1742 UTC. Dashes are about 150 msec long and spaced about 775 msec apart, for a PRI of about 925 msec. All with some pulse to pulse variation, but making about 65 dashes per minute. When I first looked at it 15 minutes before that the freq was around 8193.5 kHz, so it shifted up 200+ Hz in 15 minutes.
Beacon 2 is also a dasher, center frequency about 8194.5 kHz. Frequency looks fairly stable although the dashes have a pronounced sag down in frequency during the pulse. This sag is about 150 Hz from beginning of pulse to end. The dashes are about 525 msec long and the spacing is about 550 msec, for a PRI of about 1075 msec, or about 56 dashes per minute.
