@moonbase - can I join the floater 3 brigade?


It is a given, you are one of only two UK dx men on the forum to lock these signals in recent times as far as I know?
Back in the days when analogue was still in general use and dx men were more abundant there may have been someone around who locked them?
However that would been some years ago.

Ultra Extreme Fringe reception indeed, well done.

I have a tit for sale if interested
What kind of tit? A boob, a blue tit or a Titanium LNB?

I have one in the garage but I don't think it has 5G filter built in. Does yours? And do you find that it works (or otherwise)?

A little less analogue, and a lot more crap.

@Captain Jack

Sorry mate, actually i need that tit, as i have bad interference in my area...i was thinking i had two 5g filtered Tits, but only 1 is.....

However, i have A or B for loan or sale.....

Any chance I can borrow one of those (A, B or the Tit)? Try before you buy and all that!

3.7 is OK for testing on this satellite.

It did not - awful wind with showery sideways rain, which means I had to leave the majority of equipment inside the house.

I wanted to see how far I could get with the current setup without hacking anything. 58W was a given since I originally tuned the positioning of the jack arm and its holder to swing between 58W and 55E. There's also the limit of the 24" jack.

I knew that 63W had some data streams available in Ku so I went on the hunt and bingo!

View attachment 146795

The jack was fully compressed at this point and a couple of clicks away from running into its own limit so that had to be relocated.

Thankfully the picket fence looked like it wasn't going to get in the way, so nothing to do there.

After drilling another hole in the jack arm er... arm and hacking away part of the PM's frame with the grinder, I set about hunting.

View attachment 146797

First I needed to find approximately where 70W was and I had no idea whether I had clearance, uninterrupted lined of sight or any signal. I parked the dish on 63W and moved it as far west from there as it would go. After a lot of huffing and puffing, I found what I thought was some signal fumes on my F15 from 70W.

A few transponders were showing signs of life, so I connected the LT8700 receiver.

Nothing. At. All.

After about an hour of huffing and puffing, I thought I'd check the LNB output on the receiver with a multimeter. Both polarities were showing 18V :-dohSo I was stuck with horizontals. I knew that the tuner was OK, since it works with HackTV.

I checked the LNB settings and found that "C" LNB was set to 18V on input A and 13V on input and some odd LO. It was obviously used on a fancy setup back in the day. After correcting the errors of my ways, I saw some signs of life on analogue transponders. It was hard to see whether it was noise/interference from mobile networks or actual signal but cranking up LT to max suddenly revealed a watchable picture! Jackpot!

I managed to get a video from quite a few transponders but the low elevation of the satellite was an issue as I had some visible interference and the picture kept disappearing for fractions of seconds - almost like LT dropped out. This was especially evident in the low 3700 range.

I am sure there's more signal to be eeked out as I didn't play much with the LNB other than screwing it to the dish! And I don't have John's NASA level adjustments to skew, LNB position, feedhorn etc. etc. Not to mention the awful weather (though C band is less affected by rain). The LNB itself is also not in focus - it's sitting above the Ku LNB and I use the declination jack to compensate. I would like to see if I can sniff out a digital transponder as well.

For anyone who wants to try it - do. There's no way in the world I should be able to receive this satellite in the UK. The 1.8m dish is far too small but with Echostar's magical threshold extension, it's just about possible. I suspect without LTE, it would probably require a 3m dish to get a watchable picture.

@moonbase - can I join the floater 3 brigade?

Here's a clip of the ANALOGUE scan on 70W - 11 years since I last did it in the wild! I used my CRT monitor as the LCD one kept blanking out bad signal. Not sure why it's B&W here...

I think that the tv is in black and white because those analog transmission are in pal60 and your crt might not support it

You're close - it's PAL-M and NTSC, depending on which channel I am looking at. The LCD is multi-standard, so no issues there.

@Captain Jack ... A bit of overnight cooling frost seems to help reception from 70West analogue this morning - some rx fluctuation but generally better. The reduced fringe signal strength scenario of the further North you go in the UK seems to prevail as well as i think your reception on the 1.8 is better :Y .
** The dreaded 5G interference doesn't help either

I would call this interference and not rx fluctuation, it's way too frequent and strong.

@John it's pretty decent this morning -


(try to ignore the frikking dog in the background. Also, ignore the polarity, I fitted the LNB the wrong way around!)

I fitted one of @Manikm909's 5G filtered LNBs but as you can see, it's still interfering quite a lot on lower frequencies :( Need to try the Titanium that's also in the package.

BTW, do you have a different firmware on your LT8700? My menus have black backgrounds and yours doesn't.

@John another BTW, what's the last frequency you get? I just about get 3910 but absolutely nothing in the 4000 range.

You forgot to mention the ticking clock as well :D , re: filters, my external Ali-X one works quite well and does improve my 70W analogue pictures - snag is it has an upper cut-off thats very sharp after 4.2GHz so makes my Extended C-band frequency range unusable with the Norsat 8000RI 3.65 -4.8GHz lnb i'm using which is a bummer because 65West Extended C-band Digital is getting quite busy now. I did knock up a compromise solution with a OMT [see pic] which worked quite well but i have since let the single Extended C lnb go to scopus - think i'll get another one and try that system again once the weather gets a bit warmer. I'll check the menu's later CJ , i think i might have just made a display option change - dunno ?.Cband OMT.JPG

Iv'e got some 70West analyser frequency range grabs of V & H CJ, showing 5G and aircraft interference either side of what's left relatively unscathed of the poor old analogue / digital sigs - i'll pop them up asap.

'ere we go, potential candidate for one of the categories within the "floater 3" brigade?
bein sports frequency locked from Es'hail-1 at 25.5 East.

New for me - Rx from North Nottinghamshire UK, Fringe reception for me from 70.5° East Eutelsat 70B. ** Poor Rx conditions, rain.
12681 V. 16045, 1/2. DVB-S2, QPSK. ID: MTA1-HD. Vpid:2354. Apid:2357. SID:1. Looks like ProMo reel, English language.
1.2CM / Inverto HOME Pro PLL lnbf

I used to receive this satellite when I had line of sight. That means you have over 140 degree swing of your dish!
