Yes, pirate activity in the 43 meter band is very high. The other Sunday morning I heard 3 stations just around breakfast time. There are resources available if you are interested in listening. SSTV is quite often used and stations are usually USB or AM between 6800 - 6960 kHz with 6925 being a popular hangout.
