Den Helder Naval (Netherlands) 12840.5 (CF) RTTY 13:50 UTC 27 MAR 2023

13:50 UTC - Dutch Navy Den Helder Naval PBB, weak unreadable with an RTTY ID loop. The signal is currently too weak into my location for a proper decode; Shift: 850 Baud: 75.

Partial decode from the RTTY transmission: 04B 06A 08B 12A

Known loop message is:
02A 04B 06A 08B 12A 16X 22X
02A 04B 06A 08B 12A 16X 22X PBB
