[hpsdr] Mercury sees first RF here

[K1rqg at aol.com]

Phil et all,
 
I have been running successfully since SVN 2570 with a couple of  
configurations. Using
your slot assignment, I have been successful with MERCURY #6, PENY #5 &  OZY 
#4,
but have noticed instability when selecting different clock sources. The  
most stable 
configuration I have found is MERCURY #6, PENY #3 & OZY #1. Regardless  of 
the board
placement, when I select Mercury for 10 MHz clock source, there is an  
instability on
tune and CW note. I currently have PENY selected for both clock sources and  
have been 
running on 75 meters driving and out board driver and Alpha amp with great  
success. I
am using PENY J6 #13 for T/R switching. CW is perfect with no noticeable  
delay.
 
I have run level calibration on Mercury with latest SVN (as well as  previous 
one) and am
extremely impressed with performance. The most noticeable is how flat the  
response of
the receiver is over 192 KHz spectrum. I actually had to put a 50 ohm load  
right on the
Mercury BNC to eliminate outside signals. 
 
Thanks to all that have made HPSDR project a resounding success!

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!)
