The carrier was generated with an undisciplined 10 MHz DOCXO clocking an ad9851. As Markus points out, the maths puts it high by 92.5 uHz. Paul reported a positive offset of 46.3 and the difference can be explained by a -5.6 ppb error in the reference oscillator. This is consistent with Paul's and Markus' earlier measurements of the 2200m signals being low by a few ppb. It looks like the sigs made it across the pond and we can now start thinking about some EbNaut on VLF. The agreement between Paul's observed and the modelled 0.07fT field strengths is remarkable. The ERP estimate seems to have been a good guess! TX will remain on and phase coherent, pending arcs and ice. 73 and thank-you!
