[hpsdr] Mercury sees first RF here

[Phil Harman]

Hi Ron,

Need to know a little about your set up first.

1. What boards do you have in the Atlas bus and what order are they in and 
what gaps between them (if any)?
2. What clocks do you have selected in Setup>General>HPSDR>  10MHz Clock 
Source and 122.88MHz Clock Source?
3. Is the top LED on the Ozy board flashing when you run PowerSDR?

This is how I am running my HPSDR.  Atlas slot 1 is next to the power 
connector so 6 is farthest away.
I have Mercury in slot 2, Penelope in slot 4 and Ozy in slot 5 ( we are 
working to fix this slot dependency).

In Setup>General >Radio Model I have HPSDR checked and Penelope and Mercury 
checked
In Setup>HPSDR>  10MHz Clock Source  I have Penelope selected.
Setup>HPSDR>  122.88MHz Clock Source I have Mercury selected.

Hope that helps.

Happy Christmas (HPSDR help desk still working on Christmas Day!)
