[Elecraft] Echo when transmitting

[Matt Zilmer]

That would be my first question too.  How about checking your LINE IN
to see that there is no signal on it.  If you have it connected to a
sound device, there could be non-MIC input happening, along with your
voice audio.  Or you could have your own voice audio coming into the
input from both the MIC and the computer / sound device if the sound
device's monitor audio is enabled.
