K3 TX Audio Response

Hello,

Interested by the K3 TX audio response, i've followed
a good idea from Larry (N8LP) to get an answer.

Using  LP-PAN followed by PowerSDR as display and
SpectrumLab as generator, i've done 2 screen captures
uploaded in the "Photos" section of  the LP-PAN group.
(Not found where to upload pictures in this group?)

We can see the 2 "peak spectrum", one with
white noise as audio source and the other with
a 50 s sweep from 0 to 3000Hz.
(Mode USB, input LINE and "flat" TX equalizer).

I've now a better idea of the audio response.
(Until the I/F output...)
