1. A linear (class AB push-pull) amplifier can have 60-70% efficiency
2. WSPR is an FSK mode and does NOT need linear amplification

I doubt if WSPR is as good as OPERA taking all things into =
consideration. WSPR needs Linear PA at 35% efficiency. Opera works with =
an amplifier in class D or E at 90% efficiency. CW es QRS likewise works =
with D or E class amp.=20
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.

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.
