The new areas are due to become 'officially' fully operational in June 2011
- that is if the IMO and IHO don't go and change things yet again, at the
most the areas are subject to tests and may not be regular or reliable.
There should be 22 Navareas active after that date, and I have no plans to
change any of my databases until the 'official' Notices to Mariners are
published showing all the changes, otherwise it will all get far too
confusing.
I'm sure that the REU etc. will also change its database at that time
to reflect
the situation (though how this will affect logs from prior to that
date I wouldn't
like to say!), it's probably going to get a bit confusing though with
some people
already using the newer Navareas for some logs!
----------------------------
Hear,hear!
For Yand, I will surely wait until the dust has settled.
Waiting should pose no big problems. After all, the station names remain the
same.
For Yand, the only solution is to rebuild the log database, i.e. change the
logged navarea's to reflect the new situation. I have yet to look into the gory
details, but I guess writing a standalone rebuilding app. will be the cleanest
soultion.

Hi Dirk,
why would you have to rebuild the DB?
To my mind it's more or less like the DXCC countries in amateur radio: the old loggings (old QSOs) are valid up to the last day before the change is in effect, and the new loggings (new QSOs) are valid from that day on. So to me a rebuild is not only unnecessary, but in fact kind of "forbidden", because it would change the logs to reflect a situation that was not valid when the logging was done.
Just my opinion...

Hi Jörg,
That's a possible option. But..my concern is that searching or filtering the log
database will become very confusing to a Yand user. Say you wish to see only the
records for Arkhangelsk, what is Yand supposed to show AFTER the new navareas
are applied?
If the user selects 17F, only old loggings will be shown; selecting
the new 20F will show only show recent loggings. Moreover, the current navarea
17 (polar) will be assigned to NW-Canada in the new scheme.
A similar situation applies to Norwegian stations currently in navarea 1, to
become 19 in the new scheme. A station can have only 1 unique ID-letter/navarea
combination, otherwise chaos will follow.
It's a bit of a mess...

Hi Dirk,
Another complication will be caused if the Russians get their way and
a Navarea XXII is created covering the Caspian Sea, the whole thing will
get very messy, and I think you are quite right that a complete new start
is often the easiest way to deal with these problems.
One of the reasons I stopped including the REU/RNA areas in my list was
because it got far too confusing if I made a change and the REU didn't,
users were then using codes that may not have matched up to the ones
shown in there and that were in effect created by me.
Hopefully once all these changes are out of the way things will settle
down for many years to come, and we won't have to go through any changes
as radical as these ever again.
Alan.

Hi All,
Just to clarify why the situation with these new navareas is so confusing
at the moment, according to the Canadian Coastguard site the tests which
were carried out from Iqaluit, which only operates between June and November
when the polar regions are navigable, were made on 8416.5 kHz using NBDP,
rather than on 518 kHz.
I don't know if anyone heard any of these tests, or if this frequency will
be used again next June, or if there will be new transmitters operating on
518 as yet, but below are some of the messages that they sent in these tests:
NAVAREA XVII 49/2010
CANADA IQALUIT
IQALUIT MCTS HF NBDP SCHEDULED BROADCASTS ON 8416.5KHZ MODE F1B BEGINNING
JULY 1, 2010 AT 0330UTC AND 1530UTC FOR WARNINGS AND WEATHER FORECASTS FOR
NAVAREAS AND METAREAS XVII AND XVIII.
NAVAREA XVIII 53/2010
CANADA IQALUIT
1. IQALUIT MCTS HF NBDP SCHEDULED BROADCASTS ON 8416.5KHZ MODE F1B BEGINNING
JULY 1, 2010 AT 0330UTC AND 1530UTC FOR WARNINGS AND WEATHER FORECASTS FOR
NAVAREAS AND METAREAS XVII AND XVIII.
2. CANCEL NAVAREA XVIII 16/10
The Danes are also planning to build a new station in Greenland at Upernavik,
which will probably be in Navarea XVIII with Nuuk, no doubt we will see a lot
more movement in the early part of the next year, though progress may well
depend on the economic situation in many of these countries and whether funds
are still available.
Things are just as confusing in the Russia areas, where one of the
few operational
station in the new areas is at Tiksi, this is currently providing very limited
coverage to both Navareas XX and XXI - now how would we report that
in the REU?
Like I said before, better to wait for 'official' notices to be posted before
including them or things will very quickly get even more confusing.
If the polar
waters are all frozen and no sea paths exist in the winter months
then many of the
new broadcasts could be seasonal like Iqualuit anyway.
73 for now, Alan.
