In reply to those thinking 500khz frequency band 501 to 504 khz is being used to "chit chat" this is totally incorrect.
The radio amateurs normal bands that are used for chit-chat is completely different.
To use the 500khz band at all a "special notice of variation" to your amateur licence is required and not easily come by in the UK.
You need to have L/F experience;- IE as a ship or coast station R/O
have a good understanding of the theory and practicalties of use of these frequencies and to obey the rules. You cannot get one of these Nov's like you can an amateur licence these days from a cornflake packet without even knowing what a morse key looks like let alone be able to send morse code.
These Nov's are "experimental licences" and are in most case used as such and we collect data with reports from other foreign and uk stations.
We do not regard sending a 500 khz signal across the North Atlantic at 0130
in the wee hours as "chit-chat"--- we copied what Marconi himself did all those years ago with a lot lower power and smaller aerials. This is dedication.
We also experiment ourselves with aerials, different sizes and configurations and presently have 4 marine transmitters working on the 500khz band.
It is very pleasant to hear an Oceanspan TX again after 40 years and gives us a bit of a kick to know that we are doing our bit to keep the maritime radio
morse alive---that we all thought was dead and gone--- not here at fort perch rock---it is still alive!! It is also about maritime radio heritage hoping that the present 501 to 504khz band will not be taken from us and the hopes of keeping the 500 ton band going as long as possible whether it be "amateur" or "professional."
All the "amateurs" here at FPR have 1st class PMG certs and all ex MN R/O's
and some ex marine electronics service personnel also.
The "amateurs also have a Maritime Radio day where ex marine radio staff who have amateur licences can communicate with others and non-maritime amateurs, this also helps to keep the era of the ship and coast station R/O's
still in the public eye----most of them have now gone---but they are not forgotton about yet so we try and keep the era of the Maritime radio alive.
Cheers 73's de ftf

Sorry, but you will lose 501-504. The new high speed NAVTEX service will use 495-505.

Hopefully the amateurs can get a slot on MF. The best hope is around 460-480.

I come to the UK often - will try to get to your station next time. It looks great.

Thanks for the info. Hope we do not lose it too soon!
If you going to visit us at FPR please send me an email PM to tell us when and what date you coming to make sure someone is there to show you around as we cannot always be there, we can arrange this, hate for you to come a long way and find it shut that particular day.
This also applies to anyone else who is planning to visit us at FPR.
Thanks and cheers ftf

It may be Licenced Amateurs using GB4FPR, but they are all no doubt former very professionals.

Glad to see licenced amateurs as a reference instead of my pet aversion radio ham..
I think if 5 ton had been left to the gods it may (in my humble opinion) been short-lived and not necessarily activated/operated by those who have the most endearment.
With navtext it is still on the wavebands and long may it continue to serve mariners in whatever commercial/safety context it was designed for.
