[hpsdr] Problem: PowerSDR glitch, or very very short interuption of receiver output

[Joe Martin K5SO]

Hello Tokio,

Mercury 60 was a test version of the Mercury FPGA code used with dual  
Mercury boards.  If you are running dual Mercury boards (even though  
PowerSDR KD5TFD6Sep2010 is for a single Mercury board) I would load  
Mercury v3.0 into both boards.

If you are running a single Mercury board I would recommend using  
Mercury v2.9a instead.

In fact, to check whether the dual IQ streams of Mercury v3.0 (or the  
test version 60) is contributing to your problem I would recommend  
loading Mercury v2.9a into a single Mercury board and then running it  
with the PowerSDR KD5TFD6Sep2010 to see if your problem disappears.

Also, see if the problem changes any if you change the audio sampling  
rate (192000, 96000, or 48000) to a lower rate if you are running  
higher than 48000.

Please let us know the results of your tests.

73,  Joe K5SO
