RTTY Questions, Again

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.

IIRC, DM780 always expects USB, so you will need to use its REVERSE
control with AFSK A ... or you could use the ALT (hold MODE-Down)
control on the K3 to make AFSK A use USB.

AFSK and FSK are LSB - if you are receiving "fine" in USB, you are
likely "inverted" in AFSK/FSK. Since DM780 does not support FSK,
try selecting AFSK_A REV.

Where is the mark set in DM780 (Program Options -> Center Marker, Other)?

In reply to this post by Ian Kahn, KM4IK

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?

RTTY Questions, Again

In reply to this post by Ian Kahn, KM4IK

Try reverse polarity in DM780. You should see reverse on top left bar.

RTTY Questions, Again

In reply to this post by Ian Kahn, KM4IK

DM780:

The default RTTY setting is 45.45 baud, 170Hz shift.

In Europe RTTY is generally send using USB irrespective of the frequency.

Reverse

In North America LSB is used on 7Mhz and below, hence the Reverse button.

Try reverse polarity in DM780. You should see reverse on top left bar.

Re: RTTY Questions, Again

All,

I've got it working now, at least on 20m AFSK A! I think the reverse
polarity in DM780 was the issue. Now to replicate on other bands!

Thank you to everyone for your help.
