While it's not the ideal solution, I connected my Powerflarm portable to
both my ClearNav and to a Dell Streak running XCSoar using a simple Cat
5 cable splitter.Â* A better way would to use a powered splitter,
something like THIS

I never had any trouble using THESE

I could not feed Flarm information to both the Butterfly Vario and the LX 9070. Flarm kept losing the configure. Richard disconnected my Butterfly from the Flarm and problem solved. I am wondering how I could you have both Butterfly and LX operational with Flarm at the same time? Thanks in advance.

Roy,

Even with carbon blocking there should have been an alarm. The carbon reduces range but should not completely block. If this was the reason this is a strong case for installing B antenna in the belly. It would have been worthwhile to send both igc files from each powerflarm to flarm team to analyze, as it includes log data for all other flarms it receives. It could be a flarm display configuration issue. Unfortunately there is no standard nor best practice as of how to configure your display effectively. Every one configures differently, and some just keep factory defaults which are often wrong. I have both my old butterfly display and my LX9000 and the butterfly display provides more warnings than my LX9000. It should be fixed in the next LX Firmware release.

Further to the continued need for old fashioned "mark one eyeball" is recognition that Flarm does not work in all geometrical situations.
I was an unwitting participant in a comp near miss where 2 gliders (both with correctly configured, non stealth set Flarms) failed to detect an imminent collision with the two gliders approaching each other 45 degrees off of head on and one slightly higher than the other. It was over in a matter of seconds, and fortunately we saw each other at the last moment, he pulled and I pushed, and he passed close over me. Neither of our Flarms gave any warning. In our talk about it afterwards we theorized that the carbon underbelly of the higher glider blocked the transmissions between the two Flarm antennas (both of which were mounted on our glare shields). Both Flarms continued to work properly throughout the competition.
