[K3] RTTY problem

[Mike Reublin]

Using MMTTY and AFSK, a USB sound card, cables to line in/out. The proper sound card
is selected in MMTTY. MAIN:MIC SEL is Lin In, the level is 7. LIN OUT level is 8. The
sound card's Windows sliders are at about 2/3 scale, nothing muted. The sound
(Creative) card is producing a diddle. VOX is on. Mode is DATA, AFSK A 45
bps.Mark/Shift is 2125/170 in both the K3 and MMTTY.

On receive, nothing shows on the MMTTY scope, and nothing is decoded. If I change
bands, the scope displays both the wavy line and the waterfall for about 7 seconds,
then it all goes away, dropping off the bottom of the display.

The K3 does not go into transmit.
