RTTY

[allen rodgers]

Hi all,

 I have a new K3/100 that I am trying to put on RTTY and PSK31.  The problem I am having is a feed back of audio (loopback?) from the K3.  I am using Line-in/Line-out on the K3 and Microphone-in, Line-out on the computer in conjunction with N1MM.  The problem seems to be, any audio fed into the K3 Line-in is outputted at a lower level on the line-out.   I've tried muting all the different lines on the sound card via N1MM, nothing seems to work.  Transmitter keying via DTS or vox does not seem to make any difference in line muting.  

Any help would be appreciated.

Is MON (monitor volume, to the left of the vfo knob) set to
zero?

Allen,

Try setting the K3's MON level to zero (hold the CMP/PWR knob in, then
rotate until the display reads MON 0).

I am not sure why this would be a problem, though, unless you have your
sound card set to feed back its input to its output as well. Personally,
I would suggest turning the loopback off in the sound card and leaving
the MON on in the radio. In the sound card's playback mixer, make sure
all of the audio sources except Wave have their Mute boxes checked
(check Mute All, then uncheck the Mute box for the Wave slider only).
