The SV-ADSB-472 module's LED was green, flashing yellow once per second which is supposed to mean it is connected to the network, yet the widget on the panel says "no signal", even when it's in the air. It was purchased in 2018 and is beyond the 3 year warranty so I removed the screws, pulled it out of the enclosure and see a fried tiny coax with smoke residue around it. I ordered a new one ($800) from ACS and picked it up this morning.
The transponder signal may have fried the module sometime after I moved the ballast out of the rudder pedal area into the nose. It had worked for a year. Maybe the Texas heat helped fry it too.
I'll mount a new antenna above the canard to get more separation from the transponder antenna. This is how the Garmin GDL39 antenna is, usually setting on the glare shield and they seem to work okay.
I picked up the new 472 module and connected it. The green led flashed yellow once per second but the PFD was not showing the unit connected initially. A little futzing, reconnecting the DB9 connector, checking settings and it started working. Messed with antennas and started getting the "Receiving" indication on the map panel widget. More futzing with antennas and coax routing....intermittent signal, then found the crimped barrel on one of the BNC connectors would slide a little bit and recrimped it.
It seems there's a large transmission of ADS-B data every 15 minutes and the CONUS, Lightning data may be less frequent but they have their own age timers displayed. It would be nice to find a "Theory of operation" for Dynon (uAvionics) and the FAA's system. Also identify where or which tower is being picked up.
Zooming the map out, the map appears a brighter color for about a 200 NM radius. There were patches at some of the larger airports further North.
