Problem with analog slave

[GaryOBX]

Sorry for the length... but I am puzzled.

I have the following setup:

Fortec Star Lifetime CLASSIC NA
SG-2100 DiSEqC Motor
Fortec 31" FS80P Dish
Fortec universal 0.4dB Single KU LNBF

I bought this system from Sadoun and set it up a few weekends ago. I'm tracking the arc pretty well, although it could use some adjusting on the far west positions.

This past week, I added a US Electronics Legacy II C/Ku analog receiver (OEM'd Drake ESR-1624U) so I can catch some analog FTA sports feeds. More specifically, some preseason NFL.

My signal chain is as follows:

LNBF --> SG-2100 --> FS LCNA --> FS LCNA Loop out --> Legacy II

The Legacy II has a single input that can be C or Ku.

Next, I heard of an analog feed on SBS6-Tr9-H-11921 for the Titans/Broncos. On my LCNA, I tune to SBS6 and make sure I am on the Ohio News channel, which is H polarity. I leave the LCNA receiver powered on.

On the Legacy II, I make sure that I have Ku and B6 (SBS6) selected. To my surprise, the game is on 15 instead of 9.

According to my research on this old analog receiver, the frequency layout for SBS6 is as follows:

Ch Freq Tr#
-- ---- ---
01 11725 01
02 11750 02
03 11774 03
04 11799 04
05 11823 05
06 11848 06
07 11872 07
08 11897 08
09 11921 09
10 11946 10
11 11970 11
12 11995 12
13 12019 13
14 12044 14
15 12068 15
16 12093 16
17 12117 17
18 12142 18
19 12166 19
20 12191 **

So while the frequency on Channel 9 is correct (11921), it was showing up on Channel 15 on my receiver (12068).

I found out that another analog feed was on this same satellite: Panthers/Jaguars on SBS6-Tr15-H-12070. Since I was already on 15, I figured maybe the game had to be higher up. I started doing some math...


Ch 9 = 11921
Ch 15 = 12068
-----
Diff 147

So, if this other game was supposed to be on 12070, if I add 147, I should be in the general area. I need to find 12217.

Channel 20 is 12191, but the max I can fine tune is +/- 16. I could only get to 12207 and I could see (through static and scrolling) the game.

Has anybody experienced anything like this? Am I missing something in the signal chain that would make this old analog receiver see the right frequencies?

Thanks for any insight your pros can provide!

for some reason analog receivers never see ku channels on the right Tp my undien 4600 does the same thing will show a test pattern for TP 11 and may receive it on 19 etc.I just learned to live with it.

easy answer.....you have a Universal LNB

Since the LNB LO frequency of a Universal is 150MHZ lower than a standard (10600 for Universal vs. 10750 for Standard) that is why it does that.

Easiest thing to do is get a standard LNB. I had the same issue when I had a Universal LNB. I couldnt go any higher than 12200 MHZ so the higher channels (18 up) I coudln't see.

some older boxes do that (My Uniden 4200 does the same thing) but my Toshiba TRX-1420's are bang on.

The issue is the OP has a Universal LNB which has the LO 150MHZ less than a standard

Thanks Iceberg! On your suggestion, I just ordered a KUL1 STANDARD Linear KU 0.4 dB LNBF from Sadoun.

 

[Mr Tony]

cool

Now on the DVB box (Fortec Classic) just change where it says "UNI" for LNB Power to 10750 on each sat and you'll be all set

The analog numbers should fall into place

Thanks Iceberg-that explains why my KU analog is off and the C Band from the six footer is ok! :up
