PowerSDR VAC volume control for Direct I/Q?

Alan WA4SCAAlan WA4SCA Member ✭✭

I have recently started using a program which uses I/Q input, and it is working perfectly with PowerSDR.  I have noticed that the RX gain control on the VAC tab has no effect on the signal level, unlike the non-I/Q feed.  Is this to be expected?

    This is by design.  The VAC output gain (volume) for IQ data is fixed.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
