Re: VLF: EbNaut transmissions on lower frequencies?, pre-tests: 6.47kHz

Hi Paul,

OK, thanks for the feedback.
I tell you the messages so you can extract more informations why they failed

Message 22.05.2016: 'cqcq dk7fc in jn49ik'
Message 25.05.2016: 'not very easy'

10 characters at 100 s symbols is the best result so far.
Do you like to proceed with further attempts? Or is it to much effort 
for you?
I have no problem with defeats.

73, Stefan
