I've found it best to use minimal K3 output (Lin Out 1) and maxing the levels on the SLUSB drivers. Ideally, you want a sprinkling of snow on the waterfalls, not a blizzard. I also max the driver TX level then adjust the Data A level to the proper level. The knobs on the SLUSB are kept at noon unless you need a finer tuning for current conditions.
If you see 'echoes' (harmonic related) of a strong signal on the waterfall, you're overdriving your input; not to be confused with IMD (shadows) being sent by some when THEY are overdriving their audio. It's also a great tool for operating remotely by routing Skype audio to/from the SLUSB and NOT getting OS sounds (or ring sounds) accidentally sent out on the air. You may have small issues on the JT modes if you do not have TCXO as the transmitter heats up (slight freq drift). I've always had the TCXO, so I can't confirm that. Others may comment about that. The slower the shift rate, the more critical the frequency accuracy is. Thankfully, the line TX setting is separate from the Data A TX level setting which is also different from the Mic settings so you don't have to (remotely) reset the levels each time you change modes. Great job Elecraft! 73, Rick wa6nhc Cameron Park, Ca -----Original Message----- From: Jim Bennett Hi Bob - I've used the SLUSB on both a K3 and a KX3 with success. The K3 had it hooked to a MacBook AIr laptop; when I moved the SLUSB to my KX3, I hooked it to an iMac. Nothing special needs to be done on the K3. In my case I ran native in the Mac OS X environment. For PSK31 I used cocoaModem and for JT9 and JT65 I used WSJT-X. Both apps work very well on both the K3 and the KX3 and both Mac hardware platforms. Again, nothing "tricky" about using the SLUSB and the Mac. The "trickyness" comes with the software apps you will be using!!! If your shack experiences any sort of RFI from common mode RF, it can affect the SLUSB. I had that issue and resolved it by winding the USB cable through a 2-1/4" mix 31 donut several times. Of course, getting rid of the common mode RF is the best solution... :-) Jim / W6JHB Folsom, CA On Sunday, Jan 19, 2014, at Sunday, 7:48 PM, Robert Nobis wrote: > I have ordered a Signaink USB for use with my K3, primarily for PSK31 and > JT65A operation, and expect delivery on Monday. > > Does anyone have any precautions or hints on proper setup of the Signalink > for use with the K3?
