Fell=20 asleep over the keyboard at 23:00 so took a guess and left the system at = 136.227=20 OP32.

 

SDR14/SpectraVue=20 was set up with dual channel receive =93dial=94 frequencies 136.000 and = 136.227 kHz=20 with mono output so the OP32 decoder was seeing both OP32 sub-bands and = could=20 dual decode VO1NA and the =93normal=94 stations DF2JP DF6NM etc. Bet it = wasn=92t=20 designed to do that as the decoder sees an extra 3dB of noise in this=20 arrangement but it seems to have sorted all the signals=20 out.

 

Now=20 off to the Telford rally.

 

73=20 and thanks for the test

Thanks  Terry 

 

This where  it  becomes a little=20  messy 

 

The  mid  band  audio =20 frequency's    are     OP32  =3D  =  1550=20 Hz   and OP8 =3D 1650  Hz

 

So  for a  carrier  frequency  = of =20 137.777  KHz  , that  gives   Rx dial  set = usb=20   of  136.227    for  = OP32   =20 and   136.127  for  OP8

 

As the  pass  bands  are  100 = Hz =20 wide  , then  these will  be   +/-  50 = Hz =20 max  

 

So  depending  on the Rx  = setting =20 accuracy , you  could  round  down  to = the =20 last  ,  20 Hz  or  7 Hz

 

Eg my  Skanti  R5003 tunes  in 100 = Hz =20 steps  , so  136.2  or  136.1 , would  = put =20 me  27 Hz  off  , which  all  being  = well  ,=20 leaves 20 Hz  or  so  to the  filter  edge=20

 

All  Joe needs  to  post  = in =20 advance  is the selected  mode  speed  as  = a =20 change  of  speed  , will  need  a  = Rx =20 re-set . I don't  think  Joe's   TX P/C = is  web=20 linked , so  there  will  not  be a  TX  = beacon=20 ,

 

 

73-G.

 

NB::  Now  if you  want , that  = could also  be  translated  to a  dial =20 set   for  LSB as the  Opera  mode  = is =20 only  1  tone ........  but  I don't  think we=20 will  go  there just yet  .. but  would  = that =20 drop  dfc39  out of the  rx pass  band .... I wonder = ..=20

If=20 Opera could specify left or right audio channels I could do both = sub-bands as=20 SDR-IQ/SpectraVue provides a two channel Rx with output on L and R = channels.=20 Maybe SL could do the split for Opera.
