How to Operate Split in DIGU Mode

Frank Kirschner

I am trying to work a DX station (VP6D) on RTTY. I clicked the SPLIT button, and a new slice was created with transmit active. As soon as I tried to transmit, the transmit function returned to slice A. I switched to slice B, which allowed me to transmit on slice B, but I could no longer receive on slice A.

I've operated CW and SSB in split mode with no trouble. In DIGU Mode, I just can't make it work.

How do you operate in split in DIGU mode?

SSDR 2.4.9
HRD and DM780 (latest version, whatever that is)

OR you could just use XIT....

I just use XIT - I have the FlexControl set with one button for XIT - tap it, and dial in any offset I want.  Works for now, but we ought to be able to run split and have the DAX  follow the TX slice....  (My comments are based on using MMTTY or other 3rd party software - I have no idea about HRD.  Every time I ask them questions I get evasive answers, so have never bought.)

For RTTY split, I keep slice A (DAX 1) as the transmit slice.  I add slice B (DAX 2) and edit MMTTY to use DAX 2 as the input and then tune B to the DX's transmit frequency.  That seems to work.  I have had trouble with getting XIT to go away after using it.  I usually have to resort to turning off the radio to get it to forget the offset.  I have also had trouble getting split to work with wsjt-x fox/hound mode and EME echo mode so I turn it off in wsjt-x.  Still learning about this fantastic radio and just 'discovered' the Auto Switch Tx feature in the CAT control panel so that may be the key to getting split to work.

To exit XIT, just click the X/RIT dropdown on the slice flag and click the XIT "0" button (to zero the XIT since next time it will probably need to be something different), and then click the XIT button to turn XIT off.  If you're using a button on the FlexControl, don't forget to reset that by clicking the main tuning button, or whatever you normally have engaged when not in XIT mode.  It's a lot easier and faster than trying to describe it!  That's what I do.  Always reset it so next time it behaves as expected.

Thanks again. I just worked Z23MD on RTTY split. It's very easy to move slice B up or down to transmit while keeping slice A stationary for RX.

Frank, just make sure in SmartCat that "AUTO SWITCH TX SLICE" is disabled. Fixed!

Lucas,

That would probably work - transmitting on Slice A and receiving on Slice B. I'll try that next.

I agree, there should be an easier way. I should be able to bring up Slice B, have SliceMaster bring up the second instance of DM780 (which it does), and then transmit on which ever slice I want.  I'll keep looking.

Frank Kirschner

That's what I want (except I use DM780 instead of FLDIGI). However, when I transmit on Slice B, the Maestro immediately switches to Slice A and transmits there.

There is a setting in SmartCAT for this, but with the Maestro, Idon't use SmartCAT; I don't even have it running. I was hoping there was a setting in the Maestro or SliceMaster fot this, but haven't found it yet.

I forgot to mention one other step: In DM780, under the File menu, go to Identities and create a new identity for Slice B to use.  Then in SliceMaster, on the Launch tab, under the B slice, set the Identity to whatever you named the additional identity.

Frank,

Using a different identity for each slice is important.  Slice Master should be preventing the same identity from being used by more than one slice at a time.  If it's not, let's call that a Slice Master defect.

Regarding your previous comment... the HRD Listener settings on the Sync tab do not affect the connection between the slice and a DM780 instance that Slice Master launches for you.  Slice Master creates a separate listener for each DM780 instance that it launches and uses presets for the options.

The listeners on the Sync tab are provided for programs launched outside of Slice Master. But note that most programs launched outside of Slice Master, wanting to control the radio, would probably work better if rather than connecting to a specific slice via the Sync tab, they connected to the special TX listeners provided on Slice Master's settings tab.  HRD Logbook, for example, works great connected this way.
