Title: UNID 8993 KHZ
Post by: East Troy Don on July 16, 2018, 1450 UTC

Started monitoring this at 14:42 UTC on 8993 USB 16 July 2018 :

"Tango, papa, golf, tango, delta, ?, uniform, 5, hotel, ?, 7, tango, 3. juliet, charlie, bravo, indian, ?, victor, 2 ....."

QRT 14:44 .     SINPO:  34-2-2-3 .   

Reappeared at 14:47 but signal too weak to identify station or narrative.

Any ideas?    Thanks, Don

8992 is a hfgcs freq, and that traffic sounds like an eam so my bet is you were tuned to 8992.

Nearby is a USCG common, 8983, that at times will have cg related ssb voice activity during the day.

Thanks, Josh.   The 750 is a very capable receiver but the calibration isn't the greatest when it gets down to the 1 KHZ mark.  Any idea which USCG station QTH?

All of them can use 8983. Well, all of them that can remote to the tx sites that is, USCG made serious changes to their hf operations. It used to be they could be found on 8983 days and 5696 nites, but now they're using ale much more actively than ever before, so they can be found all over the spectrum according to whatever freq the ale setup tells then to use.
