Monitor Audio

[Ken_ke2n]

I have been scratching my head over some issues with the monitor audio (as heard in line out and the speaker) while running FSK441 in TX DATA / DATA A.  It seems  not to be a faithful reproduction of what goes into the line in jack. But, skipping the finer points for now, one thing that had me concerned was a break in the audio stream every 15 seconds or so.  I was concerned this was some problem with my PC or audio card. It turns out that the K3 updates the PA temperature reading every so often and, when it reads the temperature, it stops making audio (!).

As far as I can tell, the output of the radio does not drop during this break, just the local audio.

I wonder if this is the expected behavior?

Here is what the audio looks like - there are two breaks of about 10-20 ms.  There are two temperatures that it reads I guess ... (audio is FSK441 CQ call)
