Re: LF: Re: LF EbNaut transmission from JN64

[Markus Vester <markusvester@aol.com>]

Also got reliable and strong results on my autodecoder yesterday evening. Unfortunately some time after midnight UT, a spontaneous samplerate jump occured on my old grabber PC, so no more decodes during the rest of the morning.

Best 73,
