Regardless of the fact that pescadores use 6215 kHz...using a distress/calling frequency for pirate broadcasting is an all-around bad idea.  The US Coast Guard has extensive DF capability and has gone after people who caused interference on, intentionally or not, distress frequencies.  Sure there are fishing fleets in South America chatting away on 6215 kHz when they should be switching to another frequency after initial contact.  Maritime stations using 6215 kHz is not the same as a land-based station broadcasting a high power signal on 4125 kHz.  You can bet the USCG was listening.

In the future, I strongly recommend avoiding safety of life frequencies like 4125 kHz.

It does seem like a frequency to avoid. Several ops in the past were busted presumably for interfering with important frequencies. Or in the case of Lad from Voice of the Night, he apparently QRM'd a Havana to Moscow CW net that some folks stateside were trying to monitor.  The guys in Ft. Meade most likely have the FCC DF department on speed dial, if you know what I mean.

If it was done once for a short time I doubt that it could be a problem. If it is done repeatedly on that  frequency or another one just as important that would be a problem. Since the band propergation was so long going into Europe going thousands of miles DF ing would be difficult for one transmisión.

DFing on HF is near instantaneous these days, with the right gear.
Many have tried out the TDoA kiwi SDR network, which takes a few minutes.
Just think how little time it would take with a network of DF experts and 3 elephant cages

QRMing the guys who are well known for their helos and DFers, is unwise.

Purely on principle, the Maritime distress channels, Search And Rescue channels, and Air Traffic Control channels should be considered sacred ground taboo.

Yes we have tried out Kiwi SDR including myself and others I have talk to off this form. It was quite interesting on how for off it shows in location with the interaction of HF propagation not like line of site FM broadcasts that have no sky Propagation going on. Even though there is better stuff out there. And again if a station gets enough of there attention I sure eventually in time they will be found. Just like all the pirate FM stations being shutdown across the country because they are considered a high priority.

Lol we should have a guide for privateering of the airwaves to help budding privateers and corsairs avoid such gross malfeasance.
