Check the RJ45 socket and cable as well…they are easily abused over time. If you have the means to look at the serial output of the Flarm on your PC (using USB to serial and terminal software (I use coolterm), its pretty easy to see if its corrupt or intermittent I guess I have seem more than 10 units like that in the last 3 years Richard Swift Avionics > On 24 Dec 2016, at 4:06 pm, Justin Couch <[email protected]> wrote: > > My club's gliders have a collection of OzFlarms in them - a separate box from > the display with GPS, Aerial and serial connectors.
