I wrote a GUI app using QT (my self-tutorial) that has a bar graph for signal strength and another for SNR. They update every 100mS and it works great for watching signal strength while moving antennas. It's based on code from dvb-apps and uses channels.conf files generated with scandvb.  When invoked, it loads the channels from the .conf file and I can choose which channel I want to monitor. I can open as many instances as I want and monitor as many channels as I want (up to the number of adapters, which is now 6).  Monitoring multiple channels simultaneously while moving the antenna works GREAT.

Well, I didn't "tidy" my code, but I did try some of the suggestions to 
use a different method of getting a unique ID.  I'm still working on 
that, but, for now, I went ahead and made it available at 
http://www.guiplot.com/strength/.  I made a web page that explains how 
to use it and a little about how I wrote it, based on dvb-apps.  Let me 
know if it works and/or if it's useful.  I would love to be able to 
contribute something to this community that has provided so much of what 
I use every day.
