UNID 8994.0 kHz (centre) STANAG 4481 02:04 UTC 17 DEC 2022

02:04 UTC - UNID STANAG 4481 (RTTY) station loud and clear and currently in an idle state, constantly repeating sync information / vectors. No traffic being passed. The station is reported to originate from Davidsonville, MD.
13:15 UTC - The station is still idle with no traffic and a whopping S+10 ~ S+20 signal.
         Detected KG-84C SYNC with 100% confidence
         Initialization vectors: F588E350A01B0A08 D08A1D0800F42807
00:00 UTC 18 DEC 2022 - The station appears to have gone silent.

Obviously, this is causing some degree of havoc with the 8992.0 kHz USB HFGCS channel.

Hi.

I have MAOC Northwood (MKL) listed there using DHFCS TX- and receiving-sites.

Hope this helps.

Thanks Thomas,

I am going to try my hand at TDoA again today. I am generally not that successful with it.
