[Elecraft] KX3 RX I/Q testing

[Barry]

Kevin,
     The I/Q output is an analog two channel audio signal, but one of the 
signals is 90 degrees delayed from the other, hence in quadrature. If 
you plug the output of the I/Q port, one channel at a time into your 
computer mic input, you will hear a wideband audio signal. There will 
not be anything magic to hear.

     FLDIG wants the receiver's filtered audio to drive it. It develops 
what it needs from a mono audio input, either line or mic in.

73,
