How long was this unit installed, how did it function when in operation, what txponder did you use it with?
It was installed 02/17/2020.
I would still have it on, but I upgrade the panel to include a Garmin GNX 375, therefore don't need it. There were no issues with it in and around the complex Los Angeles airspace.
It was using in conjunction with a King KX72A with Mode C
