[Elecraft] [K3] Direct transmit PSK31

Has anyone used successfully the direct transmt PSK31 mode, PSK D? It seems
broken to me.

FSK D appears OK. I key the rig and nice sounding RTTY comes out. It decodes
OK. I can also play text stored in the message memories. I just need to be
able to send a complete message into the memory without making a mistake. :)

When I key the rig in PSK D, a tone that sounds like PSK31 is transmitted
but it is accompanied by a regular loud tick-tick-tick several times a
second. This is heard on the monitor, and also transmitted over the air. The
characters I am sending, and which appear on the VFO 2 display and therefore
are presumably modulated on to the signal, are not decoded by the decoding
software. I have tried direct pickup via the PC mic from the K3 monitor, and
over the air, the results are the same. I have tried with the receiver set
to USB and LSB, though I'm not sure it matters with PSK31, the result is the
same.

Also when I try to send a message memory I get the report "No DVR
installed."

Although PITCH in PSK-D is set to 1000 the actual audio signal appears at
about 1084Hz.

By the way, is it possible to change the center frequency used for DATA A?
It seems centered at about 1600Hz which is tiring on the ears. But when I
press PITCH it replies N/A.
