I do not know what rigs are used on the fishing boats, but I can sure
give you
daily logs showing both american and asian fishing boats carrying on SSB
qso's on the ham bands. Mostly on 80 and 160 meters.
It is normal operation when the fishing season is open they come on the 80
meter CW end of the band and go over charts, water temps, locations and
where to set the next lines and nets. Japanese, Chinese, Indonesian, and
a few Americans.
This morning was a good S9 pair of signals on 1819.5 SSB going over the
days fishing plans.
Of course the fish net beacons cover the 160 band.
Maybe the coast guard does not monitor these freqs so has no idea what is
there?
Its been a problem here in Hawaii for sure for years now.
