Stefan and I have decided that we want to
continue the WSPR-8 test transmissions tonight, but we intend to QSY
below the Eu slot after 20:00 UT. We will stay with the alternate time
slots (DK7FC at 0, 20, 40 minutes, DF6NM at 10, 30, 50 minutes), but will
both use the same transmit frequency 136.164 kHz (RF, not
dial). We hope that this will ease the task for possible stateside receivers.
Existing monitors will not have to restart the batch script, but
only change the audio frequency in the little SndInput window.

Hi Stefan,
sorry, only just started the RX before 7 UT. So
here's your decode, delayed by 10 minutes...
2012-09-22 07:10 DK7FC
0.137429 +12 0 JN49ik
1 DF6NM/8 JN59nj 175 91
The offset was shown as DT = -0.5 so timing is
perfect.
As you said, slow DX work should be split band. From
here I would send close to the Eu slot, for example in a 10
Hz subband from 136.155 to 136.165 kHz. And perhaps 137.765 to 137.775
kHz for TA west-to-east, which would be in a DCF39 gap. This setup
would also allow to merge the accelerated output with the "normal
WSPR" band 137.4 to 137.6 kHz.
