Wellllll drat. Installed a Becker xpder. It shows F 8 which is what flight level I'm at on the ground.... ATC can see me but not the transponder. It's a prebuilt harness. I swapped the coax cable with a new one and put new connectors on it. No luck... put a new antenna on it.... no luck... Becker guy in Florida says "send it in we'll check it" I've exhausted every option that I know of. I'm 99% sure it's the transponder. It's getting bench tested soon depending on shipping speed...
Thanks,
Brian
