DSP for KX1 and K1

[William Shappley-2]

The nature of the KX1 (and the K1, hope to build one of those soon)  
would argue for a very low power,
simple DSP.  Since they are CW only rigs, Autonotch doesn't make  
sense to me (wouldn't it attack
the CW note you are trying to hear?).  Also, the KX1 built in crystal  
variable filter works FB for me.  So,
I think my preference would be a denoiser only - I'm sure you could  
fit that in the K1, maybe in a KX1.

73,
Bill

If a really low power DSP could be made for the K1 and/or KX1 - say, one
that consumes 10 to 15 mA from a nominal 6V supply, less from a higher
voltage - which features would you be seeking?

Selectable bandpass filters?  Auonotch?  Denoiser?

Which would you be wiling to give up?

No, there is no project like this in the works, but I tend to think
about DSP...

Thanks!

Having just started to use a K1, I would love to have a simple DSP in it. The things I immediately miss from my K2's DSP are the denoiser and the high frequency audio rolloff. The ability to dial in a narrower filter might be useful, but I don't feel a strong need for it.

I don't really feel a need for a denoiser in my KX1, but I tend to operate it "in the wild" where there isn't a lot of QRN.
