Yes Clemens

 

I am  using m-delt4   sound  card , with   opera  to  one  channel  and  wspr to the  other , the  soundcard is  mixing the  two  data  streams ...making a  better  job, than  using the  same  sound card ...   Rf  path  is   the  racal  ma1723  exciter , direct on 500  KHz , feeding   , now ,  qty 2  skanti  solid state  trp8500  250w pk o/p class  ab2  linear amps  via a  resistive  splitter  , the  amps  are  looking  into  a  5  port  (1.5 kw)  combiner , audio  drive  is set to  below  agc action , or  the  modes change the  pk power of the  other

 

All  this  to  make   15  watts  per  carrier  ! but  the  system is  wide  band and will  work  up to  30 MHz , all  I do  is  change the  ATU ...

It wouild appear that if one is txing  WSPR and OPERA parallel on one

TX,the TX and (a possible) power amp wouild  have to be linear,

i.e. at least in class AB ?
