    Subject: KY 97a transponder problem
    From: "peteohms" <apeterchristensen@sbcglobal.net>
    While flying through class c airspace, a controller reported that my transponder was squaking the wrong code. Is there a simple solution to fixing this? Pete Hell Paso, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=184863#184863

    Pete, I didn't know there is a KY-97A. But assuming your transponder has the familiar four switches (and not a keypad or pushbuttons): about the only simple thing you can do without opening the unit is to cycle the code select switches through their entire ranges a few times. Switch contacts can oxidize (and fail to make contact) if they're not actuated occasionally and many of us leave our transponders with "1200" set for long periods of time.

    Sorry Joe it was KT 76a. And thanks allot. I'll try the cycling. That sounds like it could help.
