[hpsdr] mercury-EU synchronized with mercury-TAPR

[Phil Harman]

Hi Wully,

Congratulations on getting both models of Mercury board working.  I expect 
you can see from the USB protocol how Mercury either provides  or receives a 
10MHz clock from C16. Sorry but I can't answer your question re Mercury-EU.

73 Phil....
