Re: LF: LF and VLF EbNaut

[Markus Vester <markusvester@aol.com>]

Hi Joe,

do you know those offsets? So far I've received a carrier from you on the nominal frequency and got good asterisk decodes with fairly flat phase.  Nothing on 479 yet.

Best 73,
Markus

Hi Markus,

There will be dds and DOCXO offsets on LF. The VLF is GPS disciplined.
I got off to a rough start -- but the next frame (2300) should be good.  Thanks for your online resources!

73 & GL
Joe
