Re Qu. 1: Note that QSK requires that both the VOX and the QSK
indicators be activated; if QSK is visible on the K3's display but VOX
is not, QSK will not work. Hold the left end of the band switch for VOX
and the right end for QSK. Also, do you have PTT enabled in the microHam
Router? You will have to disable PTT in the microHam Router to allow
either semi-breakin or full breakin to work.
Re Qu. 2: Which switch are you using for Reverse? The mode reverse
switch is labelled ALT; it is activated by holding the left end of the
mode switch. The switch labelled REV between A/B and A>B is actually a
momentary-contact version of A/B. If the ALT switch is not switching
between USB and LSB, then you might have a hardware problem with the switch.
Re Qu. 3: The only programs I know of that can use PSK D are the K3
Utility and G4ILO's KComm. The vast majority of PSK31 programs (Digipan,
DM780, Fldigi, MixW, MMVARI, WinWarbler, and many others) only work with
an audio mode such as DATA A. With the K3 in DATA A, check that MAIN:MIC
SEL is set to LINE IN (this is remembered per-mode, so this won't upset
your SSB settings), then use the K3's MIC control to adjust the Line In
level. Put the K3's meter in ALC mode and adjust the Line In level so
that the ALC meter reads 4-5 bars on an idling PSK31 signal. Use the PWR
control to set power (use no more than 50 watts for good linearity). The
settings that work in DATA A for PSK31 will also work in AFSK A for
RTTY, except that you don't need to worry about non-linearity and you
can run the power up to 100 watts for RTTY.
