Bob,
 
Opera  has   73.00  = Khz =20 USB     pre set for  CAT  set ups =  and =20 linked  to the  psk-reporter , showing as  = 4000 =20 meter  band , 64  was added  for  73 band with  = -3 dB=20 lower  decode  limit ,  taking  advantage of = the =20 longer qsb , there  is more  'time'  =3D better  s/n = ,=20
 
The  cycle  time  is the  = same=20 as  the  qrss  call  sign , in a  1 hour  = window ,=20 run as is for  now ?, stations will  need to  tune = the  73K=20 settings

I would like to try OPDS32 and see what=20 happens.  I don't see OP32 available for 73 band but am sure it = could=20 be[?]

Big  problem  is the  s/n Bob=20 ,
 
 qrss   and Op64  are  = in =20 the   -43   may be  -49 dB   = s/n  with=20 the  op-wspr correction  ,
Op64 is a  true  data  mode  = ,=20 your  going  need  to  be  a good  + 20 = +  25=20 dB  stronger  for  any  other data mode to  = decode ,=20 this side of the  pond , the Opera  coding  offers  = , a 3=20 way  decode   split ,
 
If  you get a  couple  of OP64 = runs =20 and  'local'  decodes  ,  the  s/n  = levels =20 will  give a  good  indication as  to  = what =20 the  path  will  support , the  s/n level  is = the =20 average  along  the  time  line ,  I think = the =20 ros-mf-2  data  mode  at  -24 -27   = dB  ,=20 about the  same as  wspr-2  is the  lowest =20 s/n   keyboard  -  keyboard data  mode  =  ,=20 next  up  mfsk  , but  you  = need =20 3K  b/w  
 
The  only  other  system  = is =20 'Wolf'  , that's a  linear  psk  mode , which I = think=20 will  go  via your  valve  tx , there  are = a  few=20 on here  that  will  remember how to  use  = it =20   ..
 
Other  than  that ?  any  = one =20 ?
