Jim et al,

you're visible here also at -18 dB.

The band is fairly quiet tonight. Twice for a few minutes around 23:23 and 23:33, there were strong Luxembourg sideband carriers simultaneously on both HGA and DCF. They were apparently caused by a 1054 Hz sinusoidal modulation test tone (sidebands at 136.484, 75 uV/m and 137.776 kHz, 13 uV/m). There was also a -20 dB second harmonic component (137.538, 6 uV/m and 136.722, 1.5 uV/m), due to the square-law charasteristic of the heating effect.

Kind regards,
Marksu, DF6NM
