Re: LF: 477 A local SSB chat band ?

Graham, Pete,

    We have been running ssb here for years on 500kHz, no problems. 

In the Fall and Winter we have a weekly ssb net on 510 kHz usb.
Bob W2ZM (WE2XGR/6) has even been copied by Finbar on ssb.

I have had good results with slow scan tv on 500 as far out as Ohio, perhaps 600kM from here.

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
