Hi Jan,
Thanks for the email, most interesting! So i'm really looking forward to
such special condx! Do i understand you correctly, you have had a 2-way
QSO on 500 kHz with a PY station? Sounds as magic as 50 MHz or so.
Ah, when i read to the end to your mail it rather sounds as if you have
been working as the radio operator on a ship?
I have an idea: Tell it to me in a loooooooong MF CW QSO, rag chewing as
some say... :-)
Also thanks for the IARU link. What i find interesting is the comment
from TF2JB. I wonder if TF3HZ knows him? Maybe a good adress to ask for
common projects with Iceland below 1 MHz.

Stefan,
I have experience as a "former" user of 500kHz.
Under certain conditions there are "ducts" which enables you with low
power to cover large distances.
One of my favourites was EU to Brazil. Mostly in the last watch
Northsea traffic was loud and clear audible off coast Rio.
This condition could last for hours. You could contact the EU
coaststation rather easy on their working channels with 250W shipstx.
However high QRN in Brazil is rather problematic but sometimes the
condx coincided with low QRN.
Offshore, QRN can be considerable less.
I experienced these "tunnels" also between LA & Hawaii and LA & New
Zealand.
Leaving Red Sea Indian Ocean to Perth radio was also a nice link.
(7000km!)
At that time I consider it as "normal" not realising that nowadays
these are remarkable events if you put in hamradio perspective.
BTW understand that Monaco seems to be 1st official country on 472kHz
as from 18/5-2012.

Hopefully all EU countries implement this new QRG at the same time,
otherwise you must keep a database in order to know were to listen for
which country.
Somewhere from 439-510kHz.
EU and making decisions together worries me.

Hi Joe, LF,
Yes, we're here of course :-)
Unfortunately i still cannot receive on MF. My RX is home made and vy
narrow band. But i'm going to have a suitable RX in some time.
BTW, what about all the 500 kHz allocations. What happens to them
when the new 475 kHz band becomes permitted? Will you have an
extended frequency range then or will you have to QSY?
And what about the chances of this band? How easy is a TA detection?
Would it be possible to have a CW QSO over that 4400 km distance?
It would be possible for me to radiate 1 kW ERP on that band, however
with a 1W (EIRP of course) limitation, this may become a problem...

Hopefully someone will read this on Baa Baa....
The beacon is running on a new frequency with a CW ID and
a 10 second carrier. Reports most welcomed.
