[hpsdr] PowerSDR vs Kiss

[Joe Martin K5SO]

Hi Berndt,

Additional comments:

1)  Initially with PowerSDR you need to run a level calibration using  
a known signal level input into Mercury and use the Setup >  
Calibration > Level Cal utility to calibrate.  You need only specify  
the frequency and level of the known source once and you only need to  
do it at one frequency.  After that the level will show correctly  
every time you run PowerSDR (unless you have a corrupted or changed  
PowerSDR.mbd file in your directory).

2)  The audio from Mercury is normally taken from the audio jack on  
the Mercury board in both KISS and PowerSDR.  While you may use an  
actual cable from the Mercury audio jack back to and audio card on the  
PC (ugh!) or a virtual audio cable from PowerSDR to the PC audio  
system (also, ugh!) you will have more latency (extra time delay)  
doing it that way and therefore it is not recommended;  the additional  
latency in those configurations makes CW operation very difficult to  
say the least.
