Walt:
I have been using Navworx through WiFi to my Android Tablet and phone for over a month.
The Nexrad seems to be working OK now. Probably a short between the headset.
The only issue I am having and which is being investigated by IFLY is that I get a "No Heartbeat" message even though I can see that the WiFi from Navworx is sending a strong signal.
I have also found that there is sometimes a significant delay between where the target is displayed on my Android tablet and where the target actually is.
Some of this is latency caused by those that fly over 18,000 feet using the 1090 frequency and my unit being relegated to the 978 frequency use by most GA aircraft.
This means the 1090 isn't direct to me, but has to go to ground where it is rebroadcast to me.
I have seen 10-15 second delays.
However, when an aircraft is equipped with 978 out as is mine, then the delay is only 2 seconds.
