Unid Military 15016 usb 1805 am 8 Sep 2021
« on: September 08, 2021, 1808 UTC »
Caught tail end of message of unid transmission.  Very good reception.

1805 "I said four overbid, repeat, I said four overbid."  Then, series of phonetically pronounced letters (IE: Yankee, tango, etc) then  "This is Bookcase out"  Then off

1817 "Standby message follows." Letters follow..... "I say again, four overbid, four overbid." then more letters.  This is Bookcase out."

This is one of the USAF High Frequency Global Communications System (HFGCS) network frequencies. These messages are common and generally simulcast on all of the network's frequencies. I sometimes use this traffic to check propagation by cycling through the network. Good practise as well for receiving and copying those phonetic letter onto paper (or screen). Characters should come at you at an approximate cadence of 1 per second.
