Funny you should mention the rsgb , as
one of there technical board members seems
to of lead the charge to the middle of the
band on wspr , all very odd , actually it
would only take the grabber chap's to review
the situation and move the window and the
job would be done , that only leaves
the wspr location to be finalised , we did
better in 3 KHz , may be the guys on the east
coast usa could take a second look at there dial
setting ?
I would suggest
that linear (frequency translation) has been
egg'd on by wspr and the latest jt6
something mode , very little use of actual data
coms , to date has occurred on 500/477 , may be the
new user group will be more
communicative ?
Wait and see .. 73

Hi
Not sure if that comment is directed at me but I was adding my ten
cents worth to an earlier comment.
There is no mandatory requirement to use narrow band modes on the
band it only seems so because it is such a narrow allocation and it makes sense
to only use the key or data. However the Genie is out of the bottle, I was
trying to form a sensible frame work for the use of SSB on the band. This IMHO
must be done as a gentleman’s agreement otherwise you will encourage the same
stupidity we see on VHF around here where the use of say 70.45 as a casual chat
channel as it has always been begets the RSGB policemen who feel it is their
right to jam the channel and be abusive. I can site the same behavior on 2m as
well. So the channel being used for a casual chat turns into an unusable channel
for all instead of a normal sensible call in to make a general call the user
stations stand by as has always been the procedure. So whichever way, you get
war and that’s not what ham radio is about. Over regulation and giving
individuals the "authority" to be objectionable just destroys a channel by
escalating the anger of the righteous to protect a cockamamie plan!!
If I was the “authority” I would have only CW and no other modes on
630m. As said above the Genie is out of the bottle because of the acceptance of
“Linear” data modes that has encouraged the use of the PC and linear
Transverters on the band so it’s a small step to transmit an SSB
signal.
Getting everybody thinking about what they are doing in a responsible
way is better than Diktat.
I rest my case.

Just a thought.....when it gets totally washed
out with SSB all 24 hours how are you going to clean it out? People in general
dont follow gentlemen's agreements they were not party too.....and "it doesnt
say I cant in the licence".
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 ,

Hi all
One SSB channel at the high edge of the band only used during
daylight hours no DXing!
73 es GL es HNY Pete M0FMT IO91UX
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
