As I install each item in my panel I am hitting it with 12 volts to make sure everything fires up.
I prepared the Molex plug for my KT76 and hit it with 12 volts (all the while with the antenna output attached to a 50 ohm dummy load.) As soon as it powered up, I heard a high pitched hum. Not loud, but present.
Anyone have a KT76? Is that supposed to happen?
Also, how do I make sure it works right? I have a scanner that will hit 1090 Mhz but what do I listen for when I power up the transponder to know it works OK?
Thanks,
HUGO
