Saw this thread and purchased the mx-350 and the mrf-250.
Set the 250 on channel 2 and have 4 emitters.
Set the 4 SAT devices in the 350 to channel 2 and to transmit
RF only and to only emit 1,2,3,4 respectively.
I get no blinking on the status light of the 250 when
pressing buttons on the 350.
When I switch the base (250) to channel 0, I do get blinking
lights but, as stated, all emitters work and I don't want
that.
What am I doing wrong here?

Want to control 4 SAT boxes...

Thanks
