Hi Luis,

Thanks for the decode. Very well. So far this is is the best distance for a message longer than just 1 character on this band...
14.25 dB in 32.6 uHz. With this strength we could transfer 5 characters or more, depending on the local QRM...

73, Stefan

Hi VLF

A bit late, but today I could play with the files and try to decode the 6 December transmission at 22 UTC

This is the result

TNX Stefan :-)
