PowerFlarm v3.40

Well, I can report that the PowerFlarm core fails to warn me of commercial traffic most of the time. In the past week, I have been within distances of concern to a Boeing 737 and a Canadair Regional jet - they descend over our gliderport into Tucson International. My transponder seems to work, though - both these aircraft took evasive action to avoid me. The Canadair was at my altitude and had to make a very steep turn away from me. Not a peep from the Flarm!

Mike - you have either installation or configuration problems. I have an original brick, and I see every airliner, towplane, glider with transponder, and GA with transponder nearby - we're under the most-used approach path for a major Canadian airport, and see traffic all day, every day. I use the standard centre-fed dipole that came with my brick. Try swapping with a known good antenna and see if the problem is cured...

Dan:

I was coming to the same conclusion and will review my installation!

Definitely keep us posted, Mike. If not an antenna issue, maybe there's also a configuration setting you have that must be tweaked?
(I definitely agree with the grumbles about the PF folks not being great at customer communications & documentation)

The PF "brick" in my '300 definitely warned me about mode C GA traffic many times!

Despite all my current misgivings, I AM keeping my eye on progress with
Flarm...

My earlier PCAS issue was an antenna issue. Try another antenna.
I assume you have the latest firmware.

Following this discussion I took a note to pay attention for traffic alerts at the same altitude. Today my PF alerted me of another plane flying at the same altitude as mine showing 0 altitude difference for at least 10 seconds while the aircraft was at the same altitude. So I suspect the suppression is indeed also based on power level. BTW, I few with Zaon since they first came out nearly 10 years ago. It was never as reliable and accurate as my PF is nowadays.
