Chris,
Most is down to qth , I have good
signals from EI/GI , can work
with 25 watts ae feed , but out
your way and over to EU , the odds stack
up
Mal gets good signals from EU , but you
can see from previous beacon tests , land
adds 10's of dB loss very quickly , costal
effect may also slue bearings and produce
shadow zones inland as well , with 75 miles ground
range , its fine for local working in the
day , much better than 160 ....
as wspr now has 2 audio bands ,
the original same dial set qrg for
opera/wspr is now defunct , unless only
wspr 2 is used , im not sure if
15 is really any use on 477 as looking
at Andys jnt coverage with 2
watts erp , its not extensive ? 2/4/8 is about max ,
8 could be too much , 6 could be
better with the 120 second qsb and similar
flash times
added to that , the existing beacons
are taking up a lot of space ?

Subject: LF: NRRL proposal for a 630m Band Plan
Personally I don't think it's all bad in a limited
sort of way. I would welcome an agreement on (1) a section for individual
beacons, and (2) a defined section for QRSS. At the moment I haven't a clue
where exactly to monitor. The idea of moving QRSS away from the centre of the
band (but even nearer the bottom) is preferable. I am sure other mode
enthusiasts would find it more desirable/helpful to know where to listen. Not so
sure about the CW calling frequency so high though.
I am surprised CW activity hasn't taken off to a
larger extent though, I regularly hear strong stations calling CQ over and over,
getting no replies. Not very encouraging.
Chris, G4AYT.
Are you aware of
this proposal?
What do you think about it?

Recommendation
From the viewpoints of NRRL we would
(at the time being) like to present the
following proposal for a 630 m
IARU Region 1 bandplan:
472 - 479 kHz (630 m)
472 - 475 kHz CW
only – maximum bandwidth 200 Hz
472.000 - 472.150
CW Beacons only (IARU coordinated)
472.150 -
472.300 CW QRSS
472.600
CW DX Calling
474.750
CW Calling
475 - 479 kHz CW + digimodes – maximum
bandwidth 500 Hz
Contests should be discouraged in this very narrow 630
m band where radio
amateurs are secondary users.
Comment:
NRRL
feels that it will be premature to further subdivide different digimodes.
This
may be better to do at the next conference, if necessary, after
considering
experiences.
