Yes that was Gus , I had a cross band
qso with him , however , from memory he was out side
the 501-504 allocation
I was surprised at the coverage in daylight ,
its unclear as to how many stations
could actually transmit SSB in the
first place , most of the amplification is based
round class e/d , which unless
you add the envelope restoration process
are unsuitable , [ unless of course AM is
considered , which may be ok for cross
town , but boarding on the anti-social , as
the carrier would need to be mid band]
One underlying problem is we are not alone
and cannot actually define wide slots
without overlapping one of the existing beacons

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 GL es HNY Pete M0FMT IO91UX

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 ,

Hi all
One SSB channel at the high edge of the band only used during
daylight hours no DXing!

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
