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 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 ,

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
