Welllllllllllllll.... My KX3 is on the list, I'm near the top of Dec 28 (00:23:59) so I am not sure at this point. I have a circuit board that has holes for a couple of iso transformers, and a pot. Will prob put something together using it when it gets here.

A serial cable plus two audio cables connected to the line in/out of my computer sound card and my K3. Tossed my homebrew interface I used with my FT-1000 in the parts box. However my laptop does not have line in/out and so far the KX3 does not have line in/out. I get odd noise that looks like hum plus some scruff when I connect my KX3 directly to my laptop. It works but do not want to transmit the noise. So some sort of isolation and level adjusting is needed beyond just the computer sliders and KX3 mike gain and speaker level adjustment. Seems to me that is. So for my KX3 I just picked up the TRRS and TRS right angle connectors and plan to hook up one of my unterminated SL-USB cables ( short Ethernet cut in half) to play. Given the SL-USB is in my go kit anyway with my laptop. May use one of the inexpensive interface boards I found on eBay with a couple transformers and transistor switch. Or just grab some resistors and audio isolation transformers out of my parts boxes, i.e. dust off my old interface board. So yes, with the KX3 seems an interface is needed. Was very happy to read that in the future a firmware update might include having the speaker out and microphone in be switched to line out and in for the data modes. What do you use with your KX3??? 73, tom n4zpt On 5/3/2012 9:32 AM, nr4c wrote: > Hi, Steve, > \ > I really think the SL-USB is a real nice interface if you need an > interface.
