[Elecraft] :K2 Homebrew external digital interface with build-in soundcard device

[Behiels jean-Pierre]

Hi Elecraft members;

I already have build a K2/10.
My next project is to homebrew a digital interface for general purpose with
external soundcard into a separated Elecraft EC2 project enclosure.
Is there anyone who could give my some addresses and advise witch kind of
soundcard is usuable for this purpose ?
I presume a standard PC soundcard is not really useful for build-in in a
EC2-box without any PC support(connectors and so on)
You must now that I must solder my DC transceiver PC isolation circuit to
this soundcard as well.
I presume I could not solder on a standard PCI slot of sutch soundcard,not
talking about supplying this unit and so on
I will work with some small audio transformer,and some opto couplers for the
DC isolation between both.
(transceiver and PC USB port).
I look forward to receive some idees and any good designs and some usefull
information (addresses where to buy)around.
I hope someone could help my with my request.

Kindly regards Jean ON4AEF.
