Mark: Both PRFRMNJ and therepo have given good advice. If you want to have a second receiver at a later date you are better off starting with a D34 switch. In your switch and in your Antenna menu, you set up Echo 7 (119W) for Port 1, Echo 8.1(110w) for Port 2, and the Echo 3 (61.5w) for Port 3 or 4. Then do a blind scan on each and you will be all set to select your favourites. After Blind scan, it is preferrable to do a Sort - I prefer alphabetic, but you do it the way you like it.
Mark: One thing I forgot to mention. The moment you go for DP34 switch with DN LNBs, you are increasing the power draw on the whole system and the burden on your receiver. some receivers such as Pansat 3500 do not like it. Therefore, you will need to separately power the DP34. You might want to just go with therepo's advice, using standard LNBs and DisEqC switch, if you do not want to be asking questions on this forum for the next week, as it has happened before with others.
I have similar situation and I use DP34 cos I still have active DN subscription. I tried using SW21 along with DP34 to get four satellites with dish 1 port plugged into one of the receiver outlets of DP34 and dish 2 port getting direct cable from 61.5. CS5K did not get signal from DP 34. Instead I connected to one of the switch ports (119) of DP34 to dish 1 pot I was able to scan 119. How can I get all three satellites? Is this a valid solution other then DisEQc? Experts please comment. Thanks
Scorp A, if you're posting in this thread because you have a FLU (or other 2500 clone, or Pansat 2500 original), you won't get SW21 to work, but you could use a 22khz on/off switch instead, just make sure the DP switch is on the OFF side so the diseqc commands can get through. Set your diseqc ports as normal with 22khz OFF, and for the bird on the 22khz ON side, set diseqc OFF (and 22khz ON, of course).
