The 910 needs to put in "satellite" mode before you enable WispDDE.

WispDDE *WILL* send a message about "unable to cancel split mode" before it 
works properly.

WispDDE will *NOT* work properly if the 910 is *NOT* in satellite mode.

WispDDE will switch bands and modes properly only if the 910 is in satellite mode.

The inability of WispDDE to recognise VFO changes is because "Bidirectional 
Interface" is turned off. You may also have an old version of WispDDE which did 
not support "transparent tuning" - I'll send you the most recent build that does 
support it, in a separate email.

I use Orbitron and WispDDE for my 910 and it works well for me on all the 
satellites I use.

Feel free to ask me any questions about the 910 with WispDDE
