I have three movable C band dishes all feeding Manhattan 1933 receivers; all with C/Ku lnbf's. At one time   all received DW  on 103W. At this point only the set with the 10.5' Winegard Pinacle receives DW; the other two, my 10.5' RayDx and my 8.5' Orbitron Spinclination won't blindscan DW. The alignment of all seems spot on. They used to tune DW. Comments? Thanks.

Good morning rikoski...
I'm not sure what your location is but in the southern part of western Canada I've tried everything to get DW back on my 9' solid spun dish. I don't get a signal to register at all on my meter on this TP. This past fall for the MLB playoffs I was getting everything with a decent signal on SES3 C band. But something has changed. I don't know if the power was reduced on the bird or if something happened to my system. Its too cold to troubleshoot now but I do miss DW and PBS as well.

For some reason the signal is weak on this transponder only a 10ft dish can receive it can not lock it with my 7/12 footer.

It's great to see everyone getting such a strong signal on the V tp's on SES3 as I did before the construction next door. I need to get behind the dish and see if the 4 foot wooden panel fence on top of the garage that the neighbor deemed necessary is blocking out some of my signal. I'll post a photo or 2 when I get home and get your opinions.

Arion; When you say 12dB in Michigan and babadem says 11.9 dB in Massachusetts what is that referenced to? (dB is a ratio.)

That is referenced to my 10’ mesh dish and my Octagon SF8008 which is all that anyone outside of an engineer with expensive test equipment can do.

I believe they are using the C/N reading or Carrier to Noise.

Since the signal is very strong across the footprint for 103 W in the US and parts of Canada, those models of dishes should have no problem with a DVB-S2 5/6 signal unless something has gone wrong with the alignment or a component. Perhaps there is an issue with the receivers for the dishes that are not able to blindscan the DW channel at this time. Have you tried bypassing any switching devices if there are any in the system? Are you able to swap the working receiver from your 10.5 Winegard to the other dishes to see if that works? Perhaps manually tuning the receiver to 4140 V 30000 DVB-S2 5/6 could help as the blindscan could be missing it perhaps. Even erasing the transponders/channels for 103 and scanning again could help even... I'm not familiar with that model of receiver, but it seems to be the problem on the effected dishes...


For the 10.5 Raydex and 8.5 Orbitron, how is their performance on vertical polarity of 103 W? Are any other channels on 103 able to scan in, and if so, how is their signal performance? Would you have a meter or another device to try to lock onto 4140 V from those dishes for troubleshooting purposes? What kind of system are you using to move the dishes? Are you comparing their performance on other satellites and transponders as an indication of the tracking being accurate?

I have the luxury of having many tools at my disposal to see the signal at all times. For you at least, you have a known good working system that you can troubleshoot and compare with.

ARION i see you have a tek2000 mesh dish.. do you have any slop in your dish? on the mount on the back of the dish on each side there is 3 holes on each side that looks like it takes bolts.. should there be 3 bolts in there on each side? will that remove the slop? My positioner never stays set.

I will swap receivers and see what happens and also compare polarities. Thanks for the suggestions.

Yeah, that 'could' cause a problem all right.  The pivot bolt alone isn't enough to keep the mount from wiggling.  You don't need bolts in all three holes on each side.  Depending on the elevation of the dish you can figure out what set of holes to use. 

For me the middle set of holes on each side work best and there should of been bolts for them in the package.  Just hand tighten them and then maybe go another complete revolution to cinch it down and use locking washers.  You don't want to tighten them too much as the metal for the saddle isn't the thickest in the world and if you over tighten you'll start to bend the saddle away from the pivot arm.

That might not be your problem as those bolt holes are more for stabilizing the elevation of the dish but anything on the mount that allows for any slop could certainly affect where your dish lands when you move it.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
