6700/RTTY/HRD DM780 Transmission does not line up with tuning lines

Rich - N5ZC

I'm in a round room looking for a corner.

I have my 6700 communicating with HRD and DM780.  I have my tones/marks set as follows:

SDR/DSP: 2125/170
DM780: 2125/170

However, when I transmit the signals appear to be 700 hz give or take higher in frequency than the tuning lines per the SDR display.  If I adjust the DM780 tones up say 2170/170 things start lining up.

Should the tones/marks line up if both programs are setup with the same tones/marks?

What I am I missing?

OK, this is probably completely off-base, but is your CW offset set to 700 Hz also? If so, there *may* be some correlation.

Set your center frequency marker to 2210 like this:

Then press the C button:

and it will center on your RTTY lines.

Thanks for the help Alex.

I was able to change the center mark using the arrows on either side of the center mark.

Which version of DM780 are you using.  I could not find where to enable the center frequency marker.

I'm still a bit curious why we need change the center mark in order to get the transmission lined up with the tuning lines.

Yah! These tabs are sometimes difficult to find :-)
Good luck with RTTY, Alex - DH2ID
