[Elecraft] [K3] need help with hiss on ssb receive

[Adrian]

´We started shipping  DSP Assembly Rev D DSPs on new K3s about November
4th, 2009. That corresponds to K3-F Serial number 3626 

It's a two year old k3 #5047´

Snippets of information above exclude this possibility.

Just dropping the highs down isn't enough. The pink noise rolloff effect
is very good using the whole range spaced properly.

thankyou N1EU

Hi,

This was a common complaint in the past.  Elecraft engineered a retrofit 
low pass filter for the RX DSP board which cuts off above 4kHz.  Or you 
can swap out for a replacement DSP board to revision D status where the 
LPF is fully integrated.  You might like to investigate what the status 
of you K3 is.

Details can be accessed via the Elecraft ordering page.
