Hi, based on my experience and frustrations, I had many issues with diseqc at switching. I tried several fancy switches and expensive ones but all return to basic problem as they cannot switch.

All my problems been fixed by purchasing SPAUN diseqc, it costs about 20€ for 4/1 switch (model something with 411). You will be amazed how all your issues with dm800 switching are over.....

Noting that my dm800 worked for about 8 months at the beginning without problem with no name switch until all problems start.

Hello,
I'm using dm800 for 3 months now. Its connected to 4 fixed satellites via normal diseqc. Since 2 weeks I started to have very strange switching problems. When I change the channels between the sats sometimes I get permanent "tune failed" other times its temporary. also when I switch back and forward sometimes the tuned failed channel come back and so on.
I thought at the beginning its a problem with the diseqc, so I changed it with new one but again the same problem.
I tried to change the simple tuner config A/B/C/D to Advanced, wasted days trying to get better results but finally I gave up. Could this be defective tuner?
Any help is appreciated.
Thanks.
