I received a Butterfly external display with my US PowerFLARM core (brick). I also ordered a PowerFLARM Portable so have been able to compare the two. The alerter volume of my Butterfly external display is much lower than the alerter volume on my portable, even when the Butterfly is a maximum and the portable is at reduced level. My Butterfly external display also has light leaks along the entire top and bottom edges. These show up as light bars that are significantly brigher than the display itself. The portable display has no visible light leaks. I contacted Butterfly and asked for comment as I did not wish to approach my dealer until I know whether these characteristics were typical of all production displays. Butterfly declined to answer my questions and forwarded my enquiry to Lee Kuhlke of FLARM USA. It seems that Butterfly is taking no responsibility for displays that were exported to USA. Lee has so far declined to provide any answer. So, if you have a Butterfly external display, will you please let me it it has light leaks, and also if the alerter volume is similar to, or significantly lower than, the portable. Photos of the light leaks available by email. thanks, Andy..

In a seperate thread I had requested help in getting Flarm contacts to show on my Clearnav. A good suggestion was to insure I had the latest clearnav software uploaded which I have confirmed. I also get the lower case flarm "f" but I am not showing any contacts on the Clearnav screen. I have experimented with all zoom levels and still no luck. Any additional suggestions?

Seperately the range is consistantly around 2.5 miles which is dissapointing given my very careful antenna and gps installation. I certainly hope there is improvement.

You should have v 2.2.0.25 (beta) loaded.

1. Always apply power to PowerFlarm first or within a few seconds of
powering up ClearNav. If you wait as long as a minute after starting
ClearNav, CN may never see the PowerFlarm serial communication.

2. Verify communication on serial port in CN (menu/settings/tools
iirc). Verify that flarm data display is "on" (menu/settings/personal
iirc).

3. You need to zoom in such that the distance scale on the center box
is about 1 mile. Any closer in / further out and you may not see your
targets. The targets show as sailplane silhouettes drawn a bit
lighter than the one that represents yourself, with orientation that
shows direction of flight and a number that shows relative altitude.
If targets are showing on a flarm external display, they should also
show on CN. I've seen this working on my display, but have not flown
in a "Flarm Rich Environment" since adding ClearNav. I'll be at R4S
in a couple of days and will have much more experience, very shortly.

4. Alerts will show on CN on the top 1/2 the display accompanied by
audio. It'll get your attention. I don't think CN displays mode c/s
contacts at present (I see these on my Butterfly display, but not on
CN) and I simply don't know about adsb.

This is obviously all work in progress.
