Thanks for your feedback. Just updated the scenario to make sure to avoid conflicts with other scenarios/mods. Normally it should fix the issue.

Radio chatter bleeds over to other scenarios

so umm is this possible i get the vampire call like 3 sec after talking is done

Glad to help. Signal Sierra November is another fun one "You should stop immediately. Do not scuttle. Do not lower boats. Do not use the wireless. If
you disobey I shall open fire on you." page 81 (pdf page 86) but my favorite is Alfa Delta "I am abandoning my vessel which has suffered a nuclear accident and is a possible source of
radiation danger" or Alfa Juliett "I have had a serious nuclear accident and you should approach with caution." page 64 (pdf 69)

Many thanks for these information Anti-Personic Bullet. I just downloaded the International code of signals quite useful indeed

I forgot to mention that there are signals specifically for freedom of navigation/innocent passage operations on page 86 and 87 (91 and 92 of the complete pdf)

Considering the US and Soviet navies use/used different codes than INTERCO I'm not sure those specific warning would have been used but they could have been. I'm also uncertain whether before the collapse of the USSR the wording would have been the same (soviet vs russian waters) because I can't find a copy of a suitable revision online.

Also the 149th page of the International Code of Signals (1969 US edition revised 2020, pub 102) might be of interest, its available online from the US national geospatial intelligence agency's website (google "international code of signals pub 102"). The 149th page is on the 153rd page of the complete pdf file.

I know there isn't anything representative in stock sea power yet, but you might want to look at the wikipedia page for Object 100 Utes, also known as Sotka, built in 1954 and still active today

Original mission gets played a few times a week. Looking forward to trying this out!
