HX50-Iraq- TxCode9 & 13

Hello.
We took over and moved a previously working setup here in Balad, Iraq. BW Hx50.
We are receiving a signal of 88 (thanks for the inclinometer).
However, we continue to get a Tx Code9 - then after 5 or 10 minutes, it goes to Code 13. BW sent a signal and said the transmit was too weak.

The LBN is P/N 1500287-0001.
Our BUC was stolen the day ofater we moved the system, so we found a replacement (legally). It looks like the one we had, but I do not know if this may be the problem.

I have verified all Manual Commissioning data w/BW.
For Pol, I was instructed not to turn the dish using the large scale on the back, but rather to turn the TIA clockwise to 59.97 (facing the dish).

I have peak the signal using your suggested methods, and have attached pictures to help show my setup & commissioning screen.

Could this be an incompatible Transmit.BUC assembly? Could the feedhorn be the wrong distance from the dish?

The part number on this BUC is not listed as an option on the "Transmitter Radio" portion of the commissioning Page

Any ideas?

Thank you

Jorge

[/quote]Let's get some terminology straight first. You said the "BUC was stolen"  but you list the LNB part number. BUC is an acronym for Block Up Converter, which is the component of that assembly that does the transmitting. It's the long cylindrical piece with the cooling fins. LNB is an abbreviated acronym for Low Noise Block down converter, which is the component that does the receiving.

The entire assembly is called a TRIA: Transmit/Receive Integrated Assembly. From front to rear, the TRIA is comprised of
1. Feedhorn
2. feedhorn coupler (the throat, or "spacer" that Eric mentioned)
3. OMT/filter (Ortho-Mode Transducer, the dull gray thing stamped 1500286 in your photo)
4. LNB (small white box)
5. BUC (transmitter)

So what I'm building up to here is to determine specifically what component or components were stolen/replaced. And the reason that's important is because the 1 watt transmitter and the 2 watt transmitter use the same housing. At a glance, the only way to tell the difference is a piece of green tape, and/or the part number decal. Green tape; 2 watt. No tape; 1 watt. The decal is usually stuck between a pair of fins, and thus rather difficult to read. And in your photo, I don't see any green tape.

You are possibly missing the feedhorn coupler, but not all TRIAs are equipped with one. So I'm unsure how that affects RF output. This rather lengthy explanation is leading to a hypothesis that your substitute hardware may include a 1 watt replacement transmitter. Some of these versions had no coupler. A 1 watt transmitter than is another possible explanation for the weak signal reported by your provider.

Well, I don't have that part number on my list Jorge. But what I did notice is that the 10325xx series is associated with the one watt ISIS family of TRIAs. I'm wondering if what you have isn't some kinda hybrid TRIA  cobbled together from spare parts. Where did you obtain this replacement unit? My list suggests two watt transmitters are more commonly associated with the 10335xx (ISIS), 10358xx (OSIRIS), 15001xx (ANUBIS), and 10370xx (ANUBIS) series.

Yours bears a similar resemblance to a spare OSIRIS-TG2 out in my shed, but can't get to it at the moment. Bear with me and I'll try to check for some more part numbers later in the day (it's GMT -6 here).

Unfortunately no. When you "tell" the modem which LNB and transmitter it's connected to, you're in effect telling the provider what kind of hardware is on the other end (they can "see" inside your modem). You can tell the modem anything you want, but it won't change the physical capabilities/limitations of whatever it physically connects through. In your part of the world - 1 physical watt is truly insufficient.

But we're not actually  there yet, remember that this is only a supposition on my part. And I unfortunately haven't been to my shed yet. Forgot I had to make a trip to Ft Campbell today. Only just now returned, so I hope you can spare me another 24 hours.

The bottom of the Tx says "HUghes  CE 0682".
The signal remained at 88 when I moved the feedhorn forward. I did repeak anyway.
My LNB (P/N  1500287-0001) is not listed on the pulldown, but I was instructed by BW to use "TG_1024572-0001".

Unfortunately, I had to leave for a few days, so I can't check the Tx radio pulldown for the P/N I found stamped on the BUC.

Thanks

Yes! I think we are getting closer to the WWW.
I have a TRIA with the mode-matched feed system.
Now I have 90-91 Rx, and BW says the Tx is fine. However, we can't get past the "waiting for first heartbeat" message.
This is strange because the HX50 got past that message with the old TRIA. The Power light had stopped blinking quickly after a reset through TELNET (a few weeks ago).
SInce then, we reset again and got the right equipment, but she wont stop blinking.
The 'advanced' screen only shows the fallback BIN as 5.8.0.35_PID. Last time, it had a newer one, with this one as fallback.
BW says they are escalating to Hughes.
Any ideas?
Would Vertical Rx and Hoz Tx being wrong have that effect?
Just in case, I took some pics of my setup to be sure I have it right. I'm wondering if the Tx is at vertical right now.

Nothing else has changed in my settings. I have the '505' directly on top, and used the large scale on the back.

Thank you

With the main polarisation scale on the back of the dish rotated so that the feed arm is at the bottom (or top) centre, and with the feed assembled as shown the receive polarisation is true Vertical and transmit polarisation true Horizontal. Having the feed support arm at the bottom is a starting position prior to applying a polarisation adjustment amount.

This page https://www.satsig.net/maps/satellite-dish-pointing-iraq.htm will give you the polarisation adjustment amount for your location and satellite. Typically a number of degrees clockwise (+) as viewed while standing behind the dish and facing forwards towards the dish and the satellite in the sky, is required for a satellite to the west of south. Use the big scale to count along the amount.

With rx=90-91(good receive) and BW saying your transmit signal is good means that your polarisation is at least about right. Any small error in polarisation adjustment amount is NOT the cause of the current symptom of abnormal heartbeat, blinking etc. This is something for the hub to resolve. The power blinking should stop once a current software version is successfully downloaded and activated.
