SES 1 101° W Horizontal "Issues" a.k.a "I want my M(e)TV"

[TvMind]

Howdy folks long time no write.

Issue(s): Horizontal transponders (esp. Weigel mux) breakup/mosaic/sputtering audio, JTV less so (but received perfectly up until a month or so ago.
Vertical is fine (Daystar). Up until recently couldn't even get any signal on Weigel Mux but JTV was perfect.

What I did to improve things: A slight westward move improved reception but only slightly (approx 72 on the micro HD, sorry no dB to post). I removed the 3-way C-Band splitter and used a 2-way to get a 1-2 db signal gain ( the power port goes to the Startrak - the micro HD doesn't have enough juice ! (1st clue) even after swapping the switching power supply it came with with a heftier linear 12 V supply (less RFI too !).
I have had issues with the uHD before signal breaking up that a reboot would clear up (clue #2 = dying tuner?) - FYI, I reinforced the IF input and removed all flux from the pcb completely with a Flux Removal Pen (MG Chemicals Cat No. 4140-P) which definitely makes a huge difference.

I went outside and pushed and pulled reflector slightly and no improvement. Pole (actually tower in yard - the neighbours love me..NOT) is plumb, checked with carpenters level. Dish was last peaked in 2017 or so, after overhauling 24" Von Weise, new Acme, fresh grease, etc. Focal length, f/d ratio etc meticulously adjusted. One panel has a tear so planning to repair that this weekend when my cousin comes over ( to help me out (old guy here) forecast calls for sunshine.

What has changed: My utility company has installed new high tension line poles (one smack dab in the middle of 101°W target! But they put it in last year and reception (of JTV (HOR) at least) was fine, BUT when they came out to transfer the wires over this year from the old (sawed in half) pole that's about when the troubles started (coincidence?), but again Daystar (VER) was fine. I always had this pole in the light of sight of 101° before with no issues. (fyi my zenith sat 74° is unobstucted, but can't test)

In the meantime Weigel mux is trying to break in MOSTLY in LATE at night (less cell usage?) (audio not video except for a frame here or there) so don't know what has changed with this mux which suddenly "woke up". I have never had to fuss with dish moves on this satellite ( the slightest move +/- motor clicks loses lock, wheres normally on C-band I can go significantly wider east or west and still have a strong signal ( have these gone "spot beam" or narrower somehow and what is the slight difference in Az listed on Lyngsat to 100.9° affect things ( isn't that the declination i.e. requiring a tweak of declination?).

Long story short (too late, ha), if I had another DVB-S2 box to try and / or a newer more stable PLL lnb ( I have been meaning to upgrade many a time but never got arround to it) I could determine if it's my antiquated receiving equipment, or my dish/feed alignment ( doubtful as it tracks everything from 55 °W to 133 ° W nicely.) or the dreaded 5G! (BUT only on HOR and not VER?).
I read another post where the OP (with his smaller 7.5 footer) played around with the illumination to peak desired transponder and reduce qrm on interfering/ stronger xpndrs (even on 103° W). So will play with that too - and cut away the RG-6 a and pull up a fresh section with new PPC and coax Seal. Open the throat cap see if any cobwebs are there and check servo operation (also changed in last maintence 10 years ago).

Finally, this will probably be the last chance I get to play with the BUD from the looks of it (providers leaving, auctioning off rest of spectrum imminent above 4.0 Ghz, and to keep the peace with neighbours so it would be nice to have that mux back for the long, cold and dark winters to comfort this old man before I call it quits and buy a VHF/UHF/FM Yagi and get MeTV, H&I from my Vermont local stations (checked at a friends today and they come in nicely - except ABC) .
Only one guy in town (Montreal) I may be able to get a receiver or PLL lnb from to try (RPS Sat) so hopefully with elimnate that as a possible culprit. Be nice to pick up a cheap or used PLL lnb to try w/o 5G BPF (money is tight )

Like others I couldn't care less about "tv" (well maybe just a liitle or a lot) it's the challenge that excites me , I can get MeTV other ways OTA (no pirate crap).

So what do you guys (and gals) think ?. p.s. I don't have a spectrum analyzer and there are def/ cell towers nearby (half a Km or so away).
Oh and time permitting will hammer out dings too and wire damaged mesh on one section for an extra dB or two. Hesitate to touch Declination, Elevation and pole mount but will play around with those a little too... Why is this mux for finicky suddenly ?(8psk, 5/6 fec, beamwidthetc.. man wish they went back to VER I think everthing would be fine! For the engineers out here does 5G QRM affect one poliarization (HOR) more than another (VER)? I understand the strong interference swamps out the input mixer/local oscilator in the hapless old C-band lnb (I think it at time affect KU too esp. LPB on 101°W KU - incidentally thos were weak or "gone' but are back almost at the time MeTV improved..hmm Terrestrial interference?

Any thoughts or suggestions ( cheap or free solutions please) greatly appreciated. Cheers.

p.p.s. Micro HD can't display Decades and Toons but records them fine so I can watch on another box/media player (Ali chip set issue). Another reason to upgrade.

Anybody interested in a nice C/KU system free ? (for next Spring/Summer 2027)

I don't know what your main issue is...but GSP microHD? I have one too and have enjoyed it over the years. It was one of my favourites. I occasionally pull it out of my satellite museum just to play and reminisce. Get a new more sensitive receiver and be sure the correct horizontal transponder voltage is hitting a hard-working PLL LNBF. This can only help.

I hold up my GT Media V9 Prime as my example of a more sensitive receiver. It's no longer available new. But it shines and helps me to receive the Weigel mux on 101W which is kind of weak on a 7.5-foot Perfect mesh dish.

Hi cyberham, and 73's

I don't have an LNBF but an LNB (polarity is via the servo on the Corotor II+) so only a fixed voltage of 18 volts to power the lnb is needed out of the Startrak 400 (It can also do LNBF 14/18V).

Funny you should mention the GT Media V9 was just looking into it and looks like it may be the ticket - and bonus has CVBS breakout port too (watch SD stuff on my GAOO!) ,

Nice to know the tuner is more sensitive but was curious if you pick up WEigel mux with your uHD , I have to use my Startrak on the DC pass port to power lnb - uHD doesn't have the juice (probably due to long run out to dish (actually under 50 ft) and losses.

p.s. Picking up a Freesat V8 cheap this week to see how it does with HOR.

I've probably never tried to receive Weigel with my microHD since I used that receiver years ago when I was Ku-bound. It never was overly strong at driving the USALS motor. However I've always had long coaxial cable runs and heavy Ku dishes.

At the current location, my coax is typically 125 feet long. So I just move the USALS motors on horizontal transponders. I have no actuator on the C dish; purely the armstrong method.

I do dish orientation using the Edision since it has a good wifi-based system of showing me the receiver's signal at the dish but I always watch C using the V9 Prime. For Weigel, my peaked signal is just above minimum C/N lock value. So the V9 Prime plays it well but the Edision struggles usually.

Now that you're talking about it, I'm going to dig out my microHD, hook it up and see how it handles Weigel compared with the Edision and V9 Prime.

 

[cyberham]

With the microHD connected this afternoon and tuned to the Weigel mux, I can receive the mux well.

My conclusion is that the sensitivity of the receivers in descending order of sensitivity is as follows:

• V9 Prime (best)
• microHD
• Edision osmio4k+

Either the V9 or the microHD could be used to watch Weigel but the Edision really could not with my given dish situation, at least during the daytime. At night, the signal is stronger here and then maybe the Edision could be used.

What is the SNR readings for these transponders? Is the signal breaking up due to low SNR or interference?

Did you inspect the feedhorn throat and wave guide for wasp nest or other blockage? Good SNR with frequent drops in decoding ( loss of SQ readings) could indicate interference from 5G.

Appreciate you checking. I should be picking these up with the tenner so still not done tuning up the bud - fell off ladder last week and hit my head!

Started over from scratch, N/S alignment, El/Decl extreme West sat, played with feed f/d checking everything and getting nice signals but still 101 west is PIA. New lnb was defective and returned it. My old one is fine but would have liked to A/B with a better lnb.

Thought it was the servo there because I was out and set everything up by the dish and flipping to HOR made a strange noise -BUT ONLY on 101 W ! All other sats skew is fine..hmm ( I have the skew almost perfect, use "Arrow" template on Zenith Sat (well nothing on 74 W to check with but Nimiq 5 at 72.6 W is closest and luckily picking up R- Pol channel from Canada to test with. Anyway picking up a new servo to try (the obvious polarity culprit).

Q. Back in the day PAS9 (74 W) was used but now I have to use closest zenith sat (Nimiq 5). I can't perfectly peak on that one which is 1 degree off (N/S alignment error). I used my trusty Brunton compass and even true noon shadow off pole to hit south.

I did have to peak extreme west by rotating mount ever so slighty so tracking extreme pretty good, but top and middle can use an elevation tweak (esp. Ku) to bring them back to where they were. No fun as the weather has been miserable and still dizzy from fall.

Oh and the Freesat V8 is crap (the tuner pixelates when the uHD is solid!) but love that SCART connector for S-Video out ! (I record to my Pio DVR and burn to DVD classic tv shows).

Stay tuned

Thanks for chiming in here. No wasps (or hornets nests) but good suggestion.

I am getting 70 and over Quality on uHD which is good but as you say the signal drops out (70 to 0 ) occasionally and much worse by day (even JTV which I used to get solid is a mess in the day. Again Daystar (VER) is fine but still not what it used to be.

I will will either have to get a BPF or go VHF/UHF for these channels but not giving up just yet!

p.s. Isn't there something between your feedhorn/lnbf BPF model and Norsat's 1500$ BPF and 5G filtering lnb's? Heck almost ready for a diy (reverse engineer) job here (microwave BPF hack) Ah where is Radio Electronics when you need it! If it wasn't for losing Ku I'd buy your lnbf in a heartbeat! Are these hard to add Ku to?

Our LNBFs are integrated with the feedhorn and no KU option. Maybe install an inline waveguide BPF such as:
