[Elecraft] K3 Audio Low Pass Filter

[paul bijpost]

Hi all,

There were some complaints about spurious DSP/DAC products *above* the K3
passband response.
The mentioned (beta) LPF board is only meant to supress those products.
It does not alter the K3 passband AF response or character.
If you don't hear any spurious above passband this LPF is not going to make
any difference for you.

It is working on both headphones and speaker outputs.
