K3 transmission problem: noise rather than audio on SSB & sometimes digital

Jim Hooper
Dear Elecraft friends,

My K3 #6884 is exhibiting a transmission problem first identified when I couldn’t check in to one of my favorite 75 m nets the other morning on SSB.  

The behavior is that it is transmitting noise.   When I increase MON volume I can hear it quite clearly.    This happens on both of two microphones, MH3 and Yamaha CM500.   It happens less frequently on digital modes (using line in) and happens for a moment at the beginning of a transmission and then goes away.

Here is a link to the audio recording I made of it using my iPhone (m4a file type).  I was not transmitting at the time as I was in TEST mode.

I have done a reset and reloaded all configuration parameters.   I am running 5.60 firmware on it and have reloaded the firmware to the K3.  

Thoughts?

Thanks in advance and happy New Year.

73,

All,

In the FWIW department, I appear to have resolved my problem.

The problem appears to be a poorly seated Line In connector.   Removed Line In connector and problem went away.  (Menu MIC+LIN = ON).   Reseated connector and problem still not present.   As a general practice, I’ll use MIC+LIN = OFF in any event.
