I have now had my unit fail twice without any indication of failure.
It still seemed to be working fine until I saw a jet whiz by real

Again, the unit turned on and seemed to be acting fine. I sent it
back to Zaon and they were great and replaced the board to fix it the
first time.

Do you know if a failed unit like yours can still pick up the glider's
own transponder? If it cannot, that would give transponder equipped
gliders an easy way to test their MRX.
