MON function and Gain running SmartSDR REMOTE mode on LAN

Thank you all for your quick replies.  Got it.  Duh.  Top slider on PC/W panel is MIC Gain.  Missed it at first because it's not labeled.  And PROC = COMP (compression).  That was a little confusing too because I expected it to be a 1-10 type setting rather than only 3 choices for amount of compression.  And the page numbers didn't make sense at first.  Since it turns out I was reading the 2014 version of the manual.  Helped a lot when I switched to 2016.  Too bad you can't use MON when running headset from PC.  However record audio feature works just fine for audio equalization purposes.  Thanks for all your help.  Got my first QSO tonight.  No longer a Flex virgin.  Thanks!
