Sound card interface

[Benson-2]

I hope to order a K3 next month and need to sell some equipment first. Can I sell the Tigertronics SignaLink USB if I intend to connect the K3 directly to the computer sound card? Or is an intermediate interface desirable?

I can't think of any reason why not. My K3 is directly connected to the computer serial port and sound card and I have not experienced any problems as a result of that.

Like Julian, I connect my K3 directly to my "on motherboard" sound card
and it works great. I also connect to a proper RS232 serial port on my
PC for rig control. If you use Ham Radio Deluxe and it's DM780 data mode
program DM780 will display the real RF frequency, corresponding to the
tones, of the K3 when operating on RTTY, etc. The K3 has built in
transformer isolation for the rear panel line in/out sockets.

HRD will also link your K3 to other transceivers/receivers to track each
other!

If you are using AFSK, a separate sound card can prevent computer  
chimes, beeps and music from being transmitted on the air.

If you are dedicating your computer sound card for radio use, as I do with my shack computer, you can just disable all the sound effects from the control panel.

Personally I'd hang on to the SignalLink, but only for the convenience of keeping the computer's sound card for other uses.
