6400 kHz Pyongyang vs. Fishing Fleets 6400 USB (again) 2250 UTC 26 Dec 18

[R4002]

6400 kHz AM Pyongyang Broadcasting Station PBS North Korea DPRK North Korean radio - hearing military or "patriotic" music at 2250 UTC and 2251 UTC, mixing with Spanish language chatter on 6400 kHz USB and data bursts on 6401 kHz (in USB mode anyway).   Good signal from the North Koreans so one wonders if the fishing fleets using the frequency can hear it as well.

BCS stations at 6400 like 6250 are often well heard in the EU. I guess that's why fishermen and pirates do not even try to broadcast there.

The fishing fleets seem to use whatever frequency they want, including offset frequencies within the legal marine HF bands.  6200 kHz to 6525 kHz is the maritime mobile 6 MHz band so 6250 kHz and 6400 kHz both fall within that allocation (technically).  Of course, fishing boat radio communications are all over HF.  6400 kHz is another easy to remember frequency, which they seem to like a lot. 

The fishing fleet chatter I've heard on 6400 kHz didn't seem to notice the DPRK broadcast signal in AM on the same frequency.  Skip zone perhaps?  Or perhaps they just don't care.  Hiding in the broadcast sidebands is more common then you'd think.  Even pirates like Old Time Radio on 6770 kHz often have QRM form pescadores using 6770 LSB or nearby frequencies....
