Oops !
It should be BELOW 2150 MHz, ie 1650...2150 MHz with inversion.
Look at my spectrums of IF after BBC.
White bars shows missed tpns, red numbers - tpn##, black numbers - IF [MHz].

I quoted you so that I could point out what I was taking issue with.Exactly what I said. In fact you quoted me saying that the A-Band and B-Band refer to chunks of the "IF Downlink frequencies". Re-read what you actually quoted!and...
IF (Intermediate Frequency) is not the same thing as the downlink frequency from the satellite. You'll notice that the Zinwell white paper doesn't refer to A-band nor B-band; they refer to Ka-Lo and Ka-Hi which are the terms used for the IF frequencies. A-band and B-band are the satellite downlink frequencies. Zinwell never sees the GHZ frequencies because their equipment is downstream from the Low Noise Block converter (LNB).
My goal was to point out that you incorrectly identified A-band and B-band as IF frequencies. A-band (19.7-20.2GHz) is converted to Ka-Hi (1650-2150MHz) by the LNB and B-band (18.3-18.8GHz) is converted to Ka-Lo (250-750MHz).
Just for reference - D10 freq/tpn map:
Code:
RHCP LHCP Broadcast Freq. L-Band Freq
01 02 18324MHz 274MHz
03 04 18364MHz 314MHz
05 06 18404MHz 354MHz
07 08 18444MHz 394MHz
09 10 18484MHz 434MHz
11 12 18524MHz 474MHz
13 14 18564MHz 514MHz
15 16 18604MHz 554MHz
17 18 18648MHz 588MHz
19 20 18692MHz 642MHz
21 22 18732MHz 682MHz
23 24 18776MHz 726MHz
It's all semantics.
And methinks you're splitting hairs. And how the F*** does that pertain to the question I was answering, anyway?
I'm and RF engineer. I know what IF means. I know how the LNB works and what it does.
The question asked, which I answered, is how the D* receivers handle the fact that Ka has more than 32 channels ("channels" in the sense of transponder frequencies) when the D* receivers only display a max of 32 transponder freq's on a given display.
My answer was that they divide A-Band (or Ka-Hi from the LNB, it doesn't matter) and B-Band (or Ka-Low from the LNB) into two "virtual slots" in the signal strength displays.
My original answer didn't go into lengthy explanations as to the way in which the LNB stacks the different satellite downlink frequencies one way or the other because it wasn't necessary to answer the question.
I also knew that the person asking the question was very familiar with all the relivent RF techniques anyway and wasn't likely to try to start an infantile urinating contest over the semantics of "A-Band" (RF frequency) vs, "Hi" (IF frequency).
Hi,
No intention to take the discussion off topic but I had a question about the channel lineup that was posted by rad (thanks for the info!
) and this seemed like the easiest way to link my question to that post.Did anyone notice that several channels such as MGM HD, Smithsonian HD, HDnet, UniversalHD are designated as "Directv HD Extra Pack". Does this mean that we can expect a change in packages and having to pay extra for these channels? On their website, I thought they had been extremely specific that the $9.99 HD Access fee would cover all HD channels that are being added. Have I completely misunderstood one or the other of these (or both
)?Thanks in advance for any info.
The rumor is that the current $9.95 HD access charge will allow you to receive the HD version of any SD channel that your base package provides.
For any HD channel that doesn't have a SD couterpart, such as HDNet, MGM-HD, etc. there would be a new package to cover those channels for the $4.95 charge.

Wait a minute... if this rumor is true, then we would suddenly have to pay for HDNet? That doesn't seem quite right... I'm not bitching about another $5.00 per month as long as it's paying for something extra that I'm not already getting for what I'm paying now.
Eh, what's the difference.... Damn you D*, you know I'll pay it anyway...
That apparently is a sign that your account has been authorized to receive the channels from Directv 10. Check channels 480, 481 and 498.

Until there is an official announcement, I wouldn't worry. Another rumor says that current (before ??) subscribers are grandfathered until next year's price increases.
Yeah, I don't actually get to riled up.... But I love to act like I am and see what happens in the forums....
If they're going all to MPEG4, does this mean we can expect to have all our Sunday NFL games in HD now? (assuming they're originally broadcast in that of course.) I ask because I had to watch part of the Ravens game which wasn't in HD and damn it looked HORRIBLE..
MPEG is just a compression scheme and not a part of the originators broadcasts,so how they originate is of no concern; your DBS company adds the compression methodology to retrans to us.. BUT there is a big thread discussing NFL leaving MPEG2 or not elsewhere; basic guess/rumor sum-up might be 50/50 in 2008 and likely in 2009.
