After obtaining flight following yesterday and establishing radar contact and squawking the appropriate code, the controller told me my Mode C was not operating and asked me what altitude I was at?
"3580," I replied, and that seemed good enough for him.
A few minutes later, he was calling my location out to an inbound twin to St. Paul.
"We've got him on the box, but we don't show an altitude," the pilot reported to him.
"He's at 3500," the controller replied. And that was that.
I'm thumbing through the Garmin 327 manual in search of anything that might provide a clue as to why the altitude is not being received at either one of these locations.
The 327 display does show a pressure altitude reading -- the correct one -- which is coming from the Dynon D100 altitude encoder.
If this is showing correctly, is there anything that I've failed to configure that is preventing Mode C?
The antenna is the cheap rod antenna from B&C. Van's has a $39 rod antenna. I don't know if this is the same antenna or whether it might be a better choice, nor do I know whether the antenna could be a source of the problem.
