10186.0 --- Unid 1340z (cf +1800Hz on USB) strong FSK-2 1200Bd/850, ~1500 Hz bandwidth, heard on 07Jan16: probably GMSK or CPFSK. Since 10186.1 KHz is operated by FUG French Navy with STANAG-4285 1200/L, they could be the same user of the FSK signal (the above f0 could be this one) buts it's just a my guess. Obviously, the two signals were not present at the same time.
