That was SM6BHZ on 508kHz LSB


Quoting M0FMT <[email protected]>:

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

Geri

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
