[Elecraft] K3 PSK no output

[Joe Subich, W4TV]

You are far better served to use DATA A with the Signalink (or
any other interface).

DATA A has several beneficial features:
1) it (typically) selects audio from the line in jack and mutes
    the microphone - meaning that one does not have background
    noise and hum from the mic interfering with the modulation or
    causing broadband interference to others
2) it disables TX Equalization so audio levels are not up/down
    depending on where in the transmit passband one is operating
3) it disables the compressor so one does not get distortion or
    generate IMD to others operating nearby
4) it changes the "scale" of the ALC meter (expanding the range
    around the "4 bar" position) so it s much easier to set the
    correct modulation level for optimum audio input level.

In short, connecting any audio interface to "Line In", using DATA A,
and setting Mic+Line = off is the proper way to use the K3 for data
modes - for both the best performance and as a "good neighbor" on
the air.
