Any thought to a 'KDSP1', an add-in DSP noise processor for the K1? I like
the small size, four bands, antenna tuner but it needs better noise
reduction!
Can the KDSP2 be 'adapted' to the K1?
Thanks,

To have a DSP Noice Reduction and AF-filter
in K1 you might put this Low Power Board inside K1:

I think it would be a hard sell for me. Going from 55ma to 135ma -
about 145% increase in current drain on receive. It may be good at
home but looks like it would eat batteries for field use.
If the DSP can be done at a much lower current it would be an interesting idea.

I agree that 80mA is much compared to K1`s own 55mA.
Elecraft KDSP2 takes 60mA (10mA in standby) and might not
go in K1. Maybe an external unit is better.
It can be left at home with
I'll take one!
Maybe we also need a K1 RTTY module

Hi,
Besides the "current" issue, has anyone used this device? My limited
experience with audio DSP's (GAP's "Hear It" inline module) is that they
work reasonably well for moderate to strong signals. But, when you get
into the low signal strength area and high noise, the seem to "cut out"
p
All:
MANY responses - most like the idea, but do not like the additional current
draw. For a KX1, the current should be nil (if possible!); for the K1 (and K2
and K3), I (me-own-self) am willing to 'take the hit' of a few more mA. If it
is an *option* (like the KDSP2), you can add it - or not
I have a W9GR audio DSP kit that I built years ago. To give you an idea
how long ago, it uses a TI TMS320C10 DSP! (The invoice is dated
9/16/92.)
Despite that, and despite the fact that it uses only 8-bit digitization,
it works amazingly well. I found the LMS noise reduction works great on
sign
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
lter in the K3.
