I ran JT65 EME for a long time using the computer sound card and had mysterious periods of no decodes even on signals I could easily see on the waterfall. This occurred even though I had carefully calibrated the clock rates. Then I bought a Tascam 122 mk II external sound card and the vast majority of missed decodes vanished. Plus you get two nice, big knobs to turn. Just make sure you install the latest firmware AND driver from the Tascam website--mine would not even work at all out of the box until I did this.
Well worth the money, and as Jim says, you don't need the interface. 73 Eric WD6DBM Jim Brown <[email protected]> wrote: >On Mon,11/10/2014 2:47 PM, [email protected] wrote: >> Keep in mind that you really don't need a signal link with the K3 >> any good sound card will work as the K3 has isolation built in. all >> you need is cables with 3.5mm plugs on the ends to plug into K3 line >> in and out. > >That's not the reason for using a better sound card.
