[Elecraft] Specs KIO3-B internal sound card

[Clay Autery]

Don't you think being "rather disappoint[ed]" in the internal sound card
is a bit demanding?  Do you really expect a 192 kHz, studio grade DAC
internal to the radio?

I understand the desire for low noise and wide bandwidth... I do.  But
to put a Focusrite Scarlett grade sound interface internal to the radio
is simply over the top.  Shoot, why not simply ask for a full 12 channel
outboard mixer/DAC be miniaturized and stuff in next to the 100 W amp,
sub reciver, etc, etc, ad nauseum.

Not trying to be a jerk...  just trying to adjust your perspective a
bit.  Hope your DXpedition goes swimmingly.  If you don't need a lot of
additional external channels, you might try one of the ASUS or other
external sound cards devices folks use with/for the LP-PAN II and other
devices...  Many of them are 192kHz, pretty low noise and a decently
flat frequency response.

73,
