[Elecraft] No line out when AGC is off

[wa9fvp]

While operating RTTY, in order to prevent amplitude variations caused by
static crashes, I like to turn off the AGC.  It always worked with my Icom
746 and I didn't care if the audio was distorted.  It provided an amplitude
limited FM signal to my Hal DXP-38.   

When I turn off the AGC on the K3, with the RF gain set to max position. 
The signal disappears on the line out port.  Using an X/Y oscilloscope,
there appears to be noise but no signal.    I can hear the very loud RTTY
signal on speaker audio and it never cuts out.     When I reduce the RF
gain, the signal appears or sometimes during fading, the RTTY signal
reappears on the X/Y scope.

 

I’m using Firmware Rev. 4.36, and DSP 2.73
