Both simultaneous messages from Joe and Rob were decoded fine after the 23 UT Slot.

Well done both!

73, Markus

Hi Markus,
The dds word was  59045922 which gives 137477.000244.  DOXCO was
good to +-10 ppb last time it was checked. The next project is a
GPS disciplined LF carrier.

73 & GL and thanks again!

Joe
