9031 USB 9.031 MHz 9031 kHz
USB mode US Navy HF activity 11-5-2017
Freshmen working Boat Dock with several other UNID stations heard talking to Freshman (YL operator).. At 1637 UTC Freshman requested re-send of transmission, then FSK transmission heard (still at 1637 UTC). 9031 kHz is supposedly a US Navy frequency per GlobalTuners DB and other sites have it as a US Navy voice and data HF frequency logged during previous exercises. Strong FSK data signal still going at 1639 UTC.
1640 UTC - Freshman calling Boat Dock, confirming three messages to be received vs. one message
1641 UTC - "we have one message we transmitted that twice" "Boat Dock this is Freshmen, we received your handover coordination, not your handover message, over"
1641 UTC - Boat Dock requesting Freshman (maybe its Freshmen) standby for handover message
1642 UTC - FSK signal back
