73, Stefan
Opera works with an amplifier in class D or
E at 90% efficiency. CW es QRS likewise works with D or E class amp.
You have to look at the bigger picture.
To get a proper evaluation transmit the same
ERP with each mode bearing in mind the inefficiency of a Linear
amplifier versus a class D or E which is over twice as efficient. The
way tests are being conducted at present are too haphazard to be
meaningful
Twice as much DC input power is needed with a
Linear amp to generate the same ERP as a class D or E.

Interesting ...
Define 'simple' ?

Hi to all,
only a question to the experts:
is the SLOW WSPR better than the simple OPERA-32 ???

I have used a virtual audio cable, with success.
For those who still try without success, here is my description in
simple words.
If your RX is a HF TRX at 136 kHz dial setting, then the tone of DF6NM
appears at 1440 Hz, the tone of DK7FC appears at 1430 Hz.
The microphone input is used and it must be defined as the standard
audio input device. This is important since the SounInput program
related always to the default input.
Then soundinput generates the audio file and replays it in SoundOutput.
SoundOutput replays it to the standard audio output device, which is
the virtual audio cable 1 for me. So VAC1 must be defined as the
standard output device!
The sound input of the WSPR software must be set to VAC1 too.
The file wspr-8_rx.bat must be edited. If the BFO frequency in the WSPR
software is 1500 Hz, then this value must be inserted for fc in the row
for the soundoutput settings.
Set the value for fc for soundinput (the row below) to 1450 Hz and save
the file.
Then double click wspr-8_rx.bat and wait some minutes. You may watch
the small souninput and soundoutput windows...
Hope it works for others as well now.
