Hi James,
started quite good, only a weak signal after the first 35 minutes for the rest of the transmission, no problems with mode A, audio quality was OK considering the bitrate.

... also no problems with the MP40 at the beginning.

Reception BelRTL Morphy Richards
 
Hi,

Reception with Morphy Richards in my home in Luxembourg, Average low fieldstrength, some dropouts, worse after 12:10 UTC with SNR's below 9dB. Rather bad sound quality, audio input level seems to be not correct.

Hi James,

same results like Simone. After the first 30 min, no reception was possible again. See graph with fieldstrength. Sound quality was not the best.

Here is a typical example what the audio spectrum looked like and a recording
from music and speech.
