I'm glad to hear another report of this. It exactly matches my

experience. Head on traffic less than a mile away - in sight ,

alerted by ZAON PCAS, and Power FLARM portable indicated nothing!

I hope FLARM will eventually recognize this problem and correct it.

Until then I don't fly without my ZAON MRX.

I seem to remember about a year ago Darryl Ramm wrote about the difficulties involved in doing what the Zaon MRX does so well. There are a lot of non-trivial problems to be solved, it's by no means straight forward.

I'll see if I can find his post; if I do I'll write again. Or perhaps Darryl will see this and re-post his excellent explanation.
