No, not a stupid question: can a 311 "see" anything on 72.7 ?

Yes, obviously I know that Eastern Arc is for MPEG4 receivers only. By "see" I mean register on the signal meter. Reason I ask is I have a 311 and portable TV I can easily carry outside. Put a dish on a pole, direct connect to the 311, load up the signal meter screen and find 61.5, then in theory a little further west and further up and I should be on 72.7. I've been fiddling with that and not finding it at all.

But then it occured to me, and I verified at lyngsat, every transponder on 72.7 is SR21500 with MPEG4, and the 311 might not be able to handle that. It does handle the 8PSK on 61.5 though.

Anybody got an EA setup and a spare 311 lying around? Care to hook it up, run a check switch and see if anything shows signal on 72?

Pepper,

The answer is NO. All of the transponders at 72.7 are using MPEG4 compression, and the only Dish receivers that will recognize all the signals from 72.7 are VIP receivers (which are all HD receivers).

Yeah, I know they all have MPEG4 compression but I was reading signal on 61.5 transponders that have MPEG4. It's the encoding and symbol rate that affect the meter, and at that point it's not looking at compression because it's not decoding anything, I thought.

Wait a second, let's see if I remember this right. 72 and 77 use 8PSK-TURBO and 61 uses 8PSK. Bet the 311 doesn't do turbo.

Guess I need to find another way to aim.

There is mpeg2 sd on 61.5 as well as mpeg4.

My phones have an intercom on them, and I just turn it on & carry a handset with me to the dish, with another handset at the source...works well.

This is getting frustrating. I do this stuff for fun all the time, then they pick the coldest week of the year to send me out there to try to find something I've never pointed at before in the freezing rain. Maybe I should give up and call dish, dangit.

If I remember correctly 311's have 8PSK tuners in them. So yes, you can use it to check signals, but of course it won't tune the video as you already know that.

All Dish uses is 8PSK Turbo... they also run QPSK turbo on 77 and 118.7 I believe.

**Iceberg** · 02-11-2010 11:23 PM

yes the 311 has a 8PSK tuner in it. Folks use them for those locals that dish says you need a 8PSK tuner to pick them up (Marquette, MI and one DMA in Louisiana IIRC)

that's why i asked in the first post, I humbly request somebody who has EA and a 311 in the closet or whatever, run check switch then tell me what if any transponders show any signal on 72. We can theorize all we want but when someone who actually can do the test tells me there is or is not anything there, that is proof.

By the way, I also tried with the motorized dish and the Coolsat 7100. I didn't have any better luck, I think it is probably the older type of tuner like the 301 and the other old dish legacy receivers.

I was basically looking for a way to get the HD channels I'm missing without risking having all my HD turned off till a tech gets here, or having to pay for something I *should* be able to do myself, or having to agree to a commitment, or whatever else they might decide is required when I call in.

Check out "the list" link at the top of the page... 05 & 07 have SIRIUS audio on them, just listed as MPEG AUDIO, but like others have said, the compression shouldn't affect the 311 from seeing the signal, just can't decode the information once you get the signal...
