Technical Support / Weak P3i transmission?
« on: March 05, 2022, 05:56:06 pm »
Hi,
I have PAW in the cockpit, and ADS-B out via certified Mode S-ES from a Trig Transponder, the source being a GNS430W.
Since the upgrade to the latest version (athough I can't put my hand on my heart and say it's definitely aligned with that) I've noticed that Vector is indicating that ground stations are barely picking up my P3i signals. I'm using PAW as a position/traffic source for two copies of SD and there has been no problem with track recording, nor is it failing to pick up and display traffic. This is definitely a new thing, and the location of the PAW has not changed. I would previously often get PAW detected at up to 60-80Km, with a good forward radial coverage.
Vector diagrams for the last 5 flights over two days as follows, PAW first and ADS-B out second.
Any ideas?
Graham
