Yes , I know so my dial is 0.473360
and in my wspr soft the "RX BFO (Hz)" is 1500

Hi Steinar,
I have changed to WSPR-64.
Important is, that our signal is on the same frequency. The transmitted
frequency is 474.2+0.66=474.86KHz.
I will start at 19:00 UTC.
Good Luck

Hi Roland

First, I made a typo in my email. It should be wspr-64 .

Markus (DF6NM) sent me this text some time ago:

"WSPR 64 can be generated and received with the current setup. You would
only have to change decimation factor from /dec=2048 to 4096, and adapt
the arguments in the waitraster commands (repeat period and leadtimes)
to full hour frames (3600 instead of 1800, etc). "

If I have not completely misunderstood Markus, I think here is the right
parameters:

For TX :

del audio1.dat
start sndoutp1.exe /sr=48000 /dec=4096 /fc=660 /fn=audio1.dat /gain=1
:loop
waitraster 3600 20
copy wspr.dat audio1.dat
sleep 5
goto loop

I will use this for RX:

del audio.tmp
del audio2.dat
start sndoutpt.exe /sr=48000 /fc=1500 /dec=128 /fn=audio2.dat
start sndinput.exe /sr=48000 /fc=1500 /dec=4096 /maxsize=200k
waitraster 3600 -24
del audio.dat
:loop
waitraster 3600 -24
del audio.dat
waitraster -120 -1.5
copy audio.dat audio2.dat
goto loop

NB! I am using fc=1500 on in- and output, but you can use your own
settings.

Hello Steinar,
I can do it. I will start with 2W on the PA according 10mW ERP on
474.86kHz.
I send you my parameters. Pleas check it.
How exact has the frequency to be? within ± 3Hz?

  PS: I still would like to make a wspr-60 experiment trying to receive
from a transmitter with reduced power, but then some of you have to do
the TXing..
