"No ADS-B out - GPS lost"

[hmanvel]

After a rewiring job to install the Dynon Com radio, I'm getting the referenced error message on my Skyview. I have an Avidyne IFD440, and the GPS signal is driving the EFIS normally. If I had a broken wire for the GPS signal I'm assuming it wouldnt work at all with the Avidyne as my nav source. Could this be a setting problem? Any other ideas of what to look for? (it's the Dynon 261 transponder)

The 440 feeds GPS through a ARINC box 429 for navigation and AP but has a separate serial feed (TX) to the 261 transponder. I suspect the latter is your issue.

Thank you Ray, I'll chase that down!
