Hi all,

Last night (29th April) the DRM transmission started late. Before 1947 UTC
there was AM on 7550 kHz. Suddenly the DRM signal appeared. Maximum SNR
reached 27.59 dB and the average SNR for the log was 23.48 dB. The average
Doppler was 0.55 Hz. Despite the high SNR the audio was very chopped up,
probably because of the lack of robustness. The result was less than 75%
decoded audio.

Enclosed is my log from last night until my DRM Log-Plotter switched the
system down at 2230 UTC.
