I don’t remember all the calls, but KS6FF sounds familiar.  When I was operating as KA2DX in Japan in the 70’s, we used to ragchew with several KS6 stations.  A couple of them worked for the educational TV system there and they were hiring technicians.  I strongly considered going down there for an interview but my time in Japan was shortened due to my dads cancer and I had to go back to the states for 6 months or so before I could get out.  That would have been an interesting experience, though.
