Hi.

I have dual 4500's with 430W and Navworx ADS-B. Weather is fairly reliable, but traffic is very intermittent. James Marks at the flight standards office has been very helpful in running a compliance report. All categories passed. So, I am assuming that any TIS-B issues are on the FAA side, not on mine.

Can you please tell me what the TRFC, FIS-B, and OSHIP counters on the ABOUT page are doing? Is this a way to ensure my system is functioning and talking to the ground stations or other aircraft?

Thanks
