How many OMs are able to radiate a CW signal on 630m that is
audible in a reasonable distance? Here in a radius of 1000km from central EU,
maybe 50?
How many of them would be even able to radiate a SSB signal that is
comfortable readable in some distance, so that at least a few SSB QSO partners
can be found? 10?
How many of them would be willing to populate the band for
a longer time (i.e. so that it it worth to discuss about SSB on MF),
"job-, XYL-, grandchildren-, neighbour-, motivation-, other projects-, QRM/QRN-,
WX-permitting"? X!
I guess that the number X is very close to 0!
There
are a number of ideas for short experiments, now that the band is new. Some of
these experiments will be done. But the time that is spent to discuss about
these modes (and all the problems) will be longer than the time the mode will be
done.
I do not really expect problems from stations working SSB for a few
hours per year whose CW signal would be 10 dB above the noise in a 250 Hz CW
bandwidth.
Lastly people will concentrate on exciting modes like CW, the
rest will come and go.

Hi Alan, Group,
Memories of QRM from SSB are still fresh
in my mind. You certainly
don't need any endorsement from me, but I think
your views are well
stated and should be heeded.

I fear that, though what you
suggest would work, it might encourage mayhem. I would prefer to see those
who feel uncomfortable using a morse key on other bands, improve their skill
on 475 by not being under HF-band like pressure. I dont listen there now but
10MHz used to be a guide for what you can expect wher SSB is not actually
banned from a narrow band. Dont forget, to SSB-only ops CW is just
interference. The plus point is they will have to make a transverter first,
but then a few badly aligned tranverters on SSB could be a disaster. I think
the Swedish station was was Gus SM?BHZ, and the SSB wiped out several DX CW
qsos I knew of at the time. It was a commercial licence not an amateur one,
so voice ID may have been in the conditions.

Hi Graham Geri and all
Warren has seen SSB first hand on the MF QRG and we have this
side also.There was an SM station (call sign forgotten?) in the early days
of 500 that added an SSB anouncement on his beacon and it worked well.
To my spec. :- "One SSB channel at the high edge of the band
only used during daylight hours no DXing!" add " Use VOX, no monologuing
allowed" to be a laissez faire operation no band plan, but fair play!.73 es

800 Hz B/W ... May be this
is something 'Wolf' can code for you ?
a b/w compression / expansion module in SL ,
to limit the tx b/w to 800 Hz must
be possible to divide by 3 and
mult by 3 with a linear shift as well ?

Hi,
I kind of like the idea of
an SSB channel. I just pulled out the conditions of my first secial license
for 160m from 1973 or 1974. That said 1815 to 1835 kHz with 10 Watts in CW,
additionally one SSB channel for 1832 to 1835 kHz, so why not trying this on
630m, too? Here in Germany we are currently limited to 800 Hz bandwidt but I
am sure we can sork towards a special license under certain conditions such
as daylight operation only .. sounds good to me!

Hi Pete
Its quite obvious that
the allocation is quite able to
support normal armature activity , and
why not ? its no longer a experimental allocation ,
its just the same as 10 or top band , un
expected results today though ! ssb sounds
odd , may be as the path is stable
, sstv ? must be a narrow mode ,
and the 'new' digital voice is 2KHz , but
that requires a linear Tx path
As for the band edge
I'm straining to
find a engineering reason , that
wspr and qrss has decided to run mid band ? Im
sure users had a reasonable discussion at the
introduction of the band , to place the modes
at the edges , with live cw a the lower
portion ? its well know that these long
carrier modes cause disruption to other
band users and are well placed at the
band edges , 'vanity beacons' is a term I have
seen noted in referral, as occupancy increases , by
users not linked or even aware of
discussions taking place on these groups , i'm sure
there will be problems leading to
the introduction of band plan's , for
some the plans form part of the licence
conditions ..
Is Opera a vanity
system ? , actually no, it compliments ros-
data mode in that the ave s/n readings
can be used to determine if a path will
support the data mode , each having the
same averaging s/n reading taken along
the time line ,

Quite
intriguing propagation on this 'new' band
From some
unexpected early 600 mile + Opera
decodes last night , to several
wspr TA decodes , [G8's again
..] to today's test
with Gary using USB-SSB voice ,
Where as at
1300z we had 5/9 signals each way
as expected over 25 miles , GI3PDN
Ray , called on CW , to give a report
of 5/9 across the Irish Sea , some
100 miles for our two signals , his CW
also in the 5/9/9 region, one wonders
how far inland the signals travelled ?
After a short 3
way qso, we closed the test round 1330z
, may not of been quite as sociable
after dark , but with a small Ae , 40 x
70 ft iv L and 35 ft Top
load vert , 50 watts pep , results
defiantly superior to say 160 mtrs
using the same Ae's
