Imac running FLDIGI,  Kenwood TS-590s using the radio's USB cable.    PSK31 on 6 meters.   The antenna is on the roof some 30' away, 20 feet up.

When I asked FLDIGI to transmit a CQ De KF6BJW, I get a loud tone coming out out the radio speaker.  My computer speakers are off.  The microphone is disconnected from the Radio.  I'm assuming this is an audio feedback loop.  I must have a setting wrong.  Any suggestions which menu to check.

I suppose there's a possibility that I'm suffering RF feedback.  I could try some ferrite beads on the lines.

Thanks in advance.

Do you have the "monitor" feature turned on on the TS590?  Is that what you're hearing. 

Also, check to make sure you have the correct audio source/target selected in Fldigi.

Finally, in Fldigi, go to "Configure", "Sound Card", the select the "Right Channel" tab.  Make sure it is all turned off unless you specifically KNOW 100% that you need one of these turned on.

Hope this helps.

a) Is the rig going into "transmit" mode?

b) Is the sound you're hearing from the rig's loudspeaker a PSK31 signal?  [If you don't know what that sounds like,
. . . . set "fldigi" to send its output to your computer's loudspeaker and listen to it.]

  It is transmitting.  The red light is on and the power meter jumps to 20 watts.

  It's not a PSK31 signal.  It's a whine which sounds much like a feed back loop.

  I had been checking the right channel to transmit.  I'll discontinue using that setting.

  As mentioned above, I'll have to check the TS-590s "Monitor" setting.
