closed loop decoder

[robrah48]

I am new to fta.I have a cs500 and a primestar dish with the 2 original lnb. I have been trying to get 97w and 103 and every time I get good signal and quality,in the upper right corner it says closed loop recorder. I will appreciate any help anyone can give me.
Thanks,Robert

It sounds like just a text header that is imbedded in the signal. For example, If I am in the tuning page and have 11936 H 20000 on the screen, "Globecast" pops up in my right corner. That's on a Merc II. On the CS5000, what are the default tp's that you're using when you see the text?

I just found that on 103W the 12178 V 25031 transponder shows "Close Loop Decoder" in it's identity string. I think that is what you are seeing, and it's not a problem.

interesting Brent. I dont see that on my 5000 and the OP PM'd me. I referred him to the board since I figured someone duplicated it

Thats what makes this place so awesome

Thanks you guys for your help. I am glad there are sites like this one when I need help.
Thanks again,Robert

Try your Merc II on it, Tony. It'll be interesting to see if it reports the same as mine. I'm using the 1.53 firmware.

I just found that on 103W the 12178 V 25031 transponder shows "Close Loop Decoder" in it's identity string. I think that is what you are seeing, and it's not a problem.

BTW, that freq/SR should be 12180 V 25000 (according to the NIT below) . Another typical Mercury II scan.
My mercury would have given the same numbers. I couldn't lock the signal with the 12178V25031 values, but get a strong lock with 12180V25000. I'm sure the Mercury can lock equally well on either.

That Closed Loop encoder thing is the "Network Name" that's found in the NIT. The interesting thing is that this transponder has two entries in the NIT, neither of which indicates the satellite (ie the satellite entry is left blank). But the two entries are {from TSREADER}:

Network Name: FEDEX
Network ID: 552 (0x0228)
Transport Stream ID: 101 (0x0065)
Original Network ID: 552 (0x0228) Version: 1
Descriptor: Network Name Descriptor
DVB-S Orbital Position: 0.0E
Frequency: 12.180 GHz
Modulation: QPSK, DVB-S
Polarity: Horizontal
Symbol Rate: 25000 MSps
FEC: 3/4


and

Network Name: CLOSE LOOP DECODER
Network ID: 1 (0x0001)
Transport Stream ID: 101 (0x0065)
Original Network ID: 552 (0x0228) Version: 1
Descriptor: Network Name Descriptor
DVB-S Orbital Position: 0.0E
Frequency: 3.950 GHz
Modulation: QPSK, DVB-S
Polarity: Horizontal
Symbol Rate: 25000 MSps
FEC: 3/4


So it seems like a receiver could either pick up the "CLOSE LOOP DECODER" or the "FEDEX" network name. Uplinkers don't seem to be very careful about keeping the info in the NIT stream accurate. These seem to have actual freq and SR, but the Orbital Position was omitted, and the Polarity seems to be wrong. The 2nd entry shows a freq of 3950, so they must have a C-band version of this transponder somewhere, or perhaps they used to.
Maybe the close loop thing has something to do with a relay from the C-band signal or something?
