I would suggest
post #5 of the Switch FAQ.
That will get you all of your LNBs and your motor connected to the first receiver.
You don't want to put most cheap diseqc switches between the receiver and the motor.
It's been reported that you -
can- use an Ecoda 22khz switch in that capacity, but I would only consider it as a last resort.
As for the 2nd receiver, the LNBs would need a second output and another diseqc switch.
You can't use one-output LNBs in this application, if they are what's generally called the Legacy type.
(voltage controlled for polarity)
edit: the Coolsat 6000 and Mercury II receivers are both good choices for running the motor.
I don't know anything about the Digiwave.
Did you actually want to connect three receivers?
If so, I'm sure we can come up with something.
