Hello John,

Probably this was my signal, i've been transmitting Opera 32 until 8 UTC 
on 137.573 kHz.
BTW i got a report by KU4XR in Tenessee:

*opds Results from overnight in Friendsville, TN. - EM75xr ( OPERA - no decodes )

2014-03-30 06:15:17 DK7FC   7258km 137573.019Hz   8mHz -48.5dBOp  94% 16.5dB
2014-03-30 02:45:09 DK7FC   7258km 137573.035Hz   9mHz -50.4dBOp  95% 15.1dB*

Conds can't have been to bad :-)

I can't explain the -20 dBc sidebands. I've measured my sidebands to be -35 dBc some time ago and didn't change anything on the LF setup. I'll check it soon again.

73, Stefan/DK7FC
