According to the Dish Tech manual on page 6, it clearly states that each of the three left ports output all three LNB signals simultaneously. Connecting to port 2 to get just 72.7 is not possible. So, the technician tip and trick is to shut down the 77 and 61.5 LNB's ( foil trick)in order to isolate only one sat signal. In other words, you can't just connect a meter to port 2 and think you can get only 72.7 when NOT connected to a DPP44 This is the way the 1000.4 works ( according to the Dish Tech manual)
Additionally, the ports 1 (77); 2 ( 72.7), and 3(61.5) operate as isolated sat signal outputs only when connected to a DPP44 switch. Connecting the switch CHANGES the way the DPP 1000.4 LNB outputs. All this is contained in the DishNetwork Technical manual for DPP systems.
Mike- you have reported some of the best signals I have seen anywhere in the country on a 1000.4. Congratulations! My problem was with TP32 on 61.5. That was my main reason to move to the bigger wing dish.
Additionally, in all configurations the port 1 has to be connected, whether to the external switch DPP44 or to a VIP receiver. In no case can only Port 2 or Port 3 with Port 1 open be used.
After making some phone calls with very experienced techs, its the general consensus that after the check switch is run on an LNB, its a royal pain in the ass to try and repeak it. The check switch actually actives the LNB and it works completely different from that time on. As such, you may very well have bad luck trying to peak in the 1k4 with a reciever powered meter such as yours. You might have a little more luck if you clear out the orbitals in the check switch, but i personally would not try peaking that lnb in. i would call another tech and use their meter. If you can get a hold of a battery powered analog meter like the Channel master you should have more luck. like i said, that is my backup. Peaking out is still a pain though.
So, if you get a self powered meter, tune in on the 3rd port and still cant get them all in its something else. It could be a bent reflector, no line of site, bad LNB (very rare from my experience) . It might just be easier to run across a tech in your neighborhood, pay em 20 or 30 bucks to peak it in and be done with it
Resetting the system is not difficult. The memory is in the receiver. You simply disconnect the entire dish sat cable and run a check switch and get "no connection" on everything. Then reconnect the cable and run check switch a second time. Others have stated this repeatedly plus it is written in the installation manual. Nowhere is it recommended that once an LNB is "activated" you will have trouble repeaking and to just call another tech with a different meter. If you follow the procedure to clear the check switch memory, it is no problem at all. The foil trick simply aids in the isolation of the sat/lnb alignment by eliminating the other LNB's from responding during adjustment using the analog meter. It is an excellent low tech method that will make use of simple analog meters much easier. In my case I left an aluminum cover permanently ( coke can cut in half fits perfectly) over the 61.5LNB to enable the LNB IN port on a 30" 61.5 wing dish for stronger signals.
Edit- Note- I was doing some more research on this mystery of port output and why there seems to be so much confusion among professionals and amateurs (me). Here is what I discovered- When using a Sat Buddy or the Bird Dog digital meters, the LNB assembly switches to
DPP44 mode ( even though no DPP44 is used) for tuning ( single output on each of three ports). Once the digital meter is disconnected and the LNB connected to a VIP receiver, it returns to
default mode which is the simultaneous output on all three ports. Using an analog meter with receiver supplying power to port 1 keeps the LNB assembly in the default mode. Now all this makes sense. Guys- when a proferssional instal;ler says he connected his professional ( read expensive ) meter to port 2 for 72.7, he gets that 72.7 signal but if you connect your cheapie $19.95 meter with the receiver connected, you will get all three sats on each of the three ports. Simple!
