Evans,
Here in Denver we use A - 1.2GHz B - 440MHz and C - 144MHz with very little activity on A currently. We have asked most users to keep W0CDS G in RPTR 2 so that Dongle and Gateway users can also connect and join us. I think about the only way to know the activity is looking on the http://www.d-starusers.org/ for current activity in the past 6 hours. Again the page is only going to show you stations using the gateway. There could be a lot of local activity you're not seeing if users don't program the gateway into RPTR 2. If you're really interested you can go to each repeater stack and look to see it's activity for the past 14 days so for our repeater W0CDS http://www.d-starusers.org/viewrepeater.php?system=W0CDS Most of the around town activity is on our B module and we typically use the C module to link with reflectors.
