6212.2 kHz or 6122.2 kHz Presuming 6212.2 kHz USB, I wonder if its the same group of fishing boats using 6212 kHz and other frequencies as a chat channel. Any actual callsigns heard?
I did a FCC DB search for active licenses under radio service codes SB - Ship Compulsory Equipped and SA - Ship Recreational or Voluntarily Equipped in Massachusetts and it came back with 2163 licenses, many of them either private individuals or fishing companies. Callsign formats are mostly WAB1234 type (AAANNNN).
