[Fred Jensen]

You might try a drop of Deoxit on the plug and then insert and remove 
several times Paula.  I've had to do that with my K2 a couple of times.

I did hear the tones (as I had before with the phones plugged into the K3 and listening via the K3 monitor). But after I plugged the Radiosport phone plug back into the K3, voila -- I have a reading on the ALC meter.
