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

Roland DL3NDR

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.
