[hpsdr] PowerSDR panadapter during TX

[Joe Martin]

Hi Heikki, 

I did not see any reply to your query so I’ll venture a question and suggestion: 

Are you using the “stitched” mode in Rx?  If so, keep in mind that the bandwidth available in stitched receiver mode is almost three times that when not in stitched mode.  Non-stitched mode bandwidth is that of a single receiver with the bandwidth being determined by the sampling rate selected in the Setup > Audio menu.  The panadapter bandwidth in Tx mode is the same as that for a single receiver (i.e., non-stitched receiver mode).  

To make the Tx and Rx bandwidth displays equal check the Setup > Hardware Config > Limit Stitched Receivers “1-Receiver” checkbox.  

Is that the problem?
