The block diagram
hi Joe,
I am a bit late for a reply, but anyway.
The way the codec is implemented is (as far I understand it) different and
more straitforward. There is no "soundcard" in the radio, but the data
stream is directly derived from the IF-DSP.
My friend Gert, OE3ZK described it as follows:

opens the K3 to equal footing with
other SDR's to fulfill the no obsolescence promise of SDR.

The USB Audio CODEC integrated circuit in the IC-7000 or IC-7600 has
the same specifications as the USB Audio C

I have just spent most of the day trying to set up one of my other radios to
receive HF

The SignalLink USB is just a $20 USB sound card with a VOX circuit added

I've got a sound good sound card that I just installed into the computer
and it already is very easy to use digital modes with the K3 without an
external device.

I don't trust the quality of an external soundcard of this price. It might be
sufficient for PSK31 but probably not for Winmor. The Signalink USB is good,
but not for 20 bucks.
I have not heard of a problem with the DSP in the IC-7200 or 7600.
>From what I have heard this is not a real soundcard
No the K3 already has transformer isolated line in and line out
connections. These make for very simple connections to onboard sound
cards and if you need an outboard sound card with just two 3.5mm audio
ports these can be had for less than 20 bucks online.
Keeping things in this fashion keeps
This is a question to the development team: are there any thoughts or
possibilities to add a USB port to the K3 or P3 which could introduce a
USB "soundcard" to the K3 like it is in the IC-7200 or the upcoming TS-
590s (?)
