[Elecraft] RTTY Questions, Again

Do you hear anything in AFSK mode?  You say you can rec've in SSB mode, what
do you hear in AFSK mode?

When you say " won't receive RTTY in AFSK or FSK modes" exactly what do you
mean?  Is it a K3 problem, or a DM780 problem?

If you use FSK D mode, and have decode turned on, you should be able to
hear, and tune so that you can see the text decode in the VFO B area of the
display.  

Have you tried any other software?  Like Fldigi, or MMTTY?

OK, I have a repeat of a question about RTTY.  My K3 (ser # 281) won't 
receive RTTY in AFSK or FSK modes.  However, it receives RTTY just fine 
in USB.  I just went through the AFSK RTTY setup instructions in Fred's 
wonderful book, but it didn't seem to make a difference.  I'm convinced 
the issue is between the chair and the keyboard, but don't have enough 
experience with RTTY to know what I'm doing wrong.  If anyone could 
point me in the right direction, I'd really appreciate it. Here are some 
of the details people are likely to want to know:

K3 is in Data mode and set to AFSK A.
CONFIG: LineIn is set to 10.
Frequency and Shift are set to 2125 and 170 Hz, respectively.
I'm using DM780 as my digital software.
I have the K3's Line Out run to my computer's Line In, and the K3's Line 
In run to the computer's Line Out.
The computer is a fully updated version of Windows 7 32-bit.

I'll gladly provide any other details as requested.

Thanks for the help again.

73,
