I had read (somewhere ?) that the GX50 to 396/496 wouldn't work. Thanks for setting me straight. I'll wire it up next week, while the plane is down for annual. ________________________________ Message 2 _____________________________________ Time: 10:38:04 PM PST US Subject: Avionics-List: Re: DIY transponder bench test From: "jetboy" sorry you can't test much at home on a transponder. Many units do not transmit when in 'test' or 'ident' so even if you have a reception device handy you wont find anything. However if you have an antenna connected and the unit gets interrogated by other sources you may be able to hear the HV power supply whistling under load as the cavity tube sends the reply. If its all hooked up to the encoder you may be able to get a check from a friendly TCAS equipped plane or a fellow aircraft owner that has a passive alert system available. Do not put any equipment or body parts too close to the antenna unless you were about to replace them anyway.
