Thanks for your reply Richard.
As I said the units I am referring to belong to friends my own unit is
an original OZ Flarm and is in perfect working condition.
But as I was on hand to observe both installations being tested. In both
cases when the known good unit was fitted the _DISPLAY _showed targets
near and far. So if you say that the RF side is OK then perhaps the
problem resides in the display driver side. Both installations used the
LX LED display and were also connected to Oudie.
The unit that you tested would have flown on may occasions with up to 20
gliders in the air. I will ask the owner to let me look at flight logs
and compare those to our Ditto Log to find more specific instances.
In any case I am sure you are dealing with at least two faulty units and
in the interest of good customer relations you should stand by the
product you sell.

Hi Simon,
Looks like Richard didn't read your email completely before replying.
"Have you checked the display device? That could be culprit or not set up
properly."
When you clearly said "This weekend we proved the installation in both
gliders. Targets were detected when the known good flarm mouse was
installed..."
Regards
Chris

Simon,
You assessment of the analysis is perhaps putting forward an incomplete or
incorrect picture.
The Flarm unit was tested and all specifications including RF output and
receive sensitivity were checked to be within specification. The unit was
also detecting a reference unit nearby.
It should be noted that you were not charged for this work.
On this, I have copied both Flarm and LXNAV.
Additionally, your flight traces were sent to LXNAV for analysis and it was
seen from those traces that the Flarm is detecting other aircraft.
Have you checked the display device? That could be culprit or not set up
properly.
May I suggest that you send in the complete system and I will evaluate.
However if a fault is found, normal repair charges will be levied.

Hi all two friends of mine are having problems with flarm mice that will
not detect targets. They have both tested their installations using another
flarm mouse that has been proven to work in flight.
One friend recently sent his unit back to the Australian agent telling
them the specific problems he was having. The unit was returned some time
later after apparently being tested. After reinstalling the unit it was
still not picking up targets.
The agents have been blaming everything except the unit for the failure to
detect targets. This weekend we proved the installation in both gliders.
Targets were detected when the known good flarm mouse was installed using
the same wiring and in both cases an aftermarket antenna (the factory one
proved inadequate even on the working unit). Immediately afterwards and
without change the faulty units were reinstalled and no targets were
detected. All three units were running the same firmware version 6.09 and
all settings were the same.
Is anyone else experiencing similar problems?
Cheers
Simon
