You're probably thinking about the NAVAREA warnings and other
maritime broadcasts; yes, they're still very much around - I copied
some from USCG Boston last night

I have a question? Do you actually need a radio that recieves SSB to
copy these signals with a RTTY decoder, or can the RTTY decoders
still copy them fine even if your shortwave radio can only recieve in
AM mode?

The decoders operate on the demodulated tones. For RTTY there are two
tones for 1 and 0. You need the radio to generate these tones by
operating in SSB mode (usually USB).
