[Elecraft] K3 Hissy and Noisy Audio

[Arie Kleingeld PA3A]

I have tried to adjust the audio of the K3 to my liking.

Hi side of spectrum: To get rid of the higher freq's I set the RX-eq 8
to minus 8dB.
Lo side of the spectrum: I tried out the RX-eq 1 and 2. Absolutely no
difference! Not even with the lo cut set to zero.
RX-eq 3 (200Hz) responded better. Set this to plus 8dB

This gives a 'rounder' sound to my ears.

I sure wish that the 100Hz and 50Hz (RX-eq 1 and 2) would show some
response. Low frequencies seem to be absent.


K3 #1255, IF-setting:
Mode LSB
2.7k 5-pole roofing
DSP to norm first, adjusted lo cut to seek for lo freq response

Headset: Heil-pro type, 320 ohm measured resistance.
