RTTY and STANAG

I have been using the Multipsk software a lot recently and here are a couple of stations successfully decoded with it. The station broadcasting "IDN" etc is the Italian Navy in Naples in STANAG, sending these CARBs (channel availability & readability broadcasts) interspersed with encrypted data, and Royal Navy RTTY CARBs from HM Naval Base, Clyde. On this latter transmission when I saw the letter "IVVB" and "PPVYG" I thought I had unearthed some Italian and Brazillian callsigns being transmitted, but alas extensive googling proved this wasn't the case, and I wonder now if these letters were just intereference! Anyway, here they both are:

I have also had a whole lot of fun monitoring German Customs Vessels in ALE mode, but I haven't time to blog about this now, so will save it for another time.
