Hi,

On a related subject. I have a customer with a new TruTrak Pictorial Turn
and Bank that is complaining of noise on the radio when the unit is turned
on. I've sold a fair number of these units with no previous complaints.
The unit has only 12V power connections -so there are not GPS RS-232 data
signals to make noise. Has anyone else had any electrical noise issues with
this product? Any suggestions? My guess is that his radio antenna or other
radio wires are poorly shielded and/or running past the TruTrak unit. Or
the TruTrak's power leads are putting noise into the radio antenna. The
unit has a small motor inside.

The manufacturer suggested sending it back to them for warranty repair. But
they didn't sound like they were confident that they could fix the problem.

Hi,

GPS data cables can be quite noisy electrically. That is why all Goddard
cables are shielded. I've never had a customer complain about electrical
noise with a Goddard cable or the PS-5a power converter.

I have a question for all the electronically minded pilots out there.
Every time I transmit my vario goes crazy. The funny thing is that
when the colibri and or the Ipaq isn't connected it doesn't go crazy.
My set up is as follows: LX 1600vario
Dittle FSG 2T radio
Colibri data logger
Ipaq 3600 running SeeYou mobile

What's the solution? I got some ferrite beads and put them in various
locations with no success.
should I shield the cables from the vario to the colibri and Ipaq???
