[Elecraft] K3 and Tascam US-122MKII

Deane:

I have the US-144, but it is similar enough to be applicable. I use the
Elecraft Line Out with a stereo cable to the Tascam Line In (L) jack. You
will need to use a 1/8" to 1/4" adapter to make this work. I use the L and
R line out jacks (RCA) with an RCA to stereo 1/8" adapter. This goes back
to the Elecraft Line In plug on the back.

You can look for the settings in Fred Cady's book for DATA A set up for the
K3.  I use FLDIGI and VOX. Works well after getting the radio set up for it.

Now, for the tricky part. You must download and configure the USB/serial
port for this external sound card. I use a Mac so have no idea about the
Winblows drivers. I must start the Tascam driver software in the background
in order for the Mac and FLDIGI to see the external sound card.

On the top of the Tascam unit, you want to do the following:
1. Phantom is OFF
2. Mic/Lin is ON
3. Mono is OFF
4. Mon Mix is fully clockwise (Computer)
5. Once you have tuned a signal on your FLDIGI waterfall, then use the
Input Left dial so that you have a blue background with a light "snow" of
yellow dots on the waterfall. Try to do this in a segment of the band
without signals. You can alternatively select a "loud" signal then adjust
the dial until the Input Left LED goes from green to red peaks ... then
back off until it always stays green.
6. The LINE OUT is adjusted differently depending on how your radio is set
up so that you do not over-drive the LINE IN to the K3.

Hope that helps.
