Hi Paul, VLF,

Wonderful! I like the long messages. The next one will be even longer.
You may have noticed that there was an 'issue' again with my system. This time the power supply collapsed :-) But the PA is my own construction and so i would understand and know how to repair it! Will repair the supply now an d then back on air. Message announcement will follow.
Ah and i ordered 2 feed-through ceramic isolators from ebay lat night
Hopefully the creepage distance is high enough :-)

73, Stefan

Another success.

Copied 'DREAMER' at rank 3,  Eb/N0 = +0.8,  BER 34.5%, constant
reference phase.   Signal averages 16.04 dB in 54.8 uHz.

A good result, considering the overnight noise.
