6732.0 KHz: another STANAG-4481F KW-46 secured channel that use the odd 3-bit pattern discussed here. This one is most likely from AJE (Barford St, John, UK) and // with 8204.5 KHz from NSY (Niscemi, Italy).

So far, it seems that only the transmissions from NSY and AJE exhibit the odd 3-bit pattern we are talking about. Below the current list of the successful frequencies:
5120.5 NSY
6383.0 NSY
6732.0 AJE (new update)
7545.5 NSY
8145.0 NSY, AJE
8204.5 NSY
As said, it's to notice that most of the times the NSY frequencies are logged as "NSY Sigonella": well, NAVCOMTELSTA (U.S. NAVAL COMPUTER AND TELECOMMUNICATIONS STATION) Sicily, located in Naval Air Station Sigonella, manages the Naval Radio Transmitter Facility Niscemi, housing LF/HF transmitters. Same story about AJE Barford St.John that probably is sometimes reported as Croughton, nearby (6 miles distant).
