Hey cj468,
Thanks for posting this log - did the stations you heard have any sort of particular accent or other identifying characteristics? 3342 kHz / 3.342 MHz is within the 90 meter broadcasting band, but that portion (2-3 MHz, and 1.6-4 MHz) seems to be very popular with fishing fleets and trawlers, including frequencies within the 80 meter band/75 meter band. I've read reports from UK based amateurs regarding Irish fishing fleets using frequencies in 80 meters for ship-to-ship chatter.
