107.3W A little help needed

[arlo]

Strange one. When I blindscan this one with my osmio4k. Nothing is found. Of course when you can catch it. Inclined orbit and all. 4163 V 1937 blasts in at over 15 dB here.
I got curious and scanned it every which way. Limiting the freq. range, sr range. Fixed it to vertical. Usually blindscan is set to Disable sync with....
Tried TNAP with the low sr avl driver. The TNAP Mod one. OpenViX. OpenATV.
She comes up blank. A manual entry in signal finder pops it in right away and strong.

Think someone could give it a shot? I asked EB but where he lives he cant receive 107W
Makes me wonder now how many hit's I've missed when doing blindscans.

Panamericana TV comes in at 4163H2400-3/4 8PSK DVB-S2 15.8 dB. There are others. I got 62 TV channels.

but that's on 117W, right? I think Arlo is talking about the last remaining Canadian (Nunavut) feed on the ageing Anik F1R @ 107W

107W is correct.Thing is, I blindscan frequently looking for wild feeds. I know the sat is inclined orbit. The reception opportunity is limited each day.
That's got nothing to do with anything. What's got me wondering right now is how many transponders might be missed in other sat scans.
The signal rate is low, yes. But not so low that the mio4k 'cant' receive it (sr 1937).
The channel was already there from a previous scan. And usually I disable using the satellites.xml in scan settings.
It's just not found in a new scan. Deleted from the xml and channel deleted from the lamedb. A scan won't find it.
Entering the details in Signal finder pops it in immediately.

Was wondering if anyone had a chance if they could try it when 107 is receivable.

i've definitely seen this type of problem on other satellites, where it mises certain transponders even on multiple blind scans, for no apparent reasons. And at other times it will find it. I don't have an explanation for it

You'll find that interesting channel also on 111.1W Anik F4 @ 4110 H 7960. Check your scanning there.

for anyone who is interested in trying it, Anik F1R's orbit just crossed the equatorial plane, so can be received like any "normal" satellite for probably the next 30 minutes.

I am seeing the exact same problem where the blind scan in TNAP 5.1 is not finding it, but the Signal Finder locks that transponder right away at 14.2 dB

now if I boot TNAP 6, the blind scan finds it just fine

then on TNAP 4.2 (with T2MI driver), no luck

and finaly a TNAP 5.1 with standard non-T2MI driver, it finds it!

so my guess is that this is a shortcoming of the T2MI-enabled driver (including the one that allows lower SR on 5.1)

while doing this, the signal increased to 15dB, not bad for that old satellite! It's now down to 14 dB. I have a doubt actually, that maybe the modified driver gives a lower dB reading by about .5 dB. Something to check...

For reference, this was tested with a 10' Winegard Quadstar, C2-PLL Titanium LNBF, Pansat 1.1 DiseQc switch and OSMIO4K receiver loaded with 4 images as described in my list above

Maybe EB can provide us with some directions on how to run the scan in some form of debug mode so that he can get more details?

Thanks Brct. You had the intuition and drive to investigate the options I was thinking about.
I am running the TNAP Mod driver in TNAP and ViX. Actually backed up the different tuner drivers to a directory on my pc.
Had to ask EB how to swap them in TNAP 6. Needed to install a driver swapper plugin no there out of the box.

I'm not that good with logs and looking through what was found, saw snipets of blindscan info. No dice though.
I was looking to see if there was a frequency sweep log. I think that I my be expecting a bit much.

Enosat over on legit showed an old plugin that resembled a spectrum analyzer. It looked cool. But I believe it was just a work in progress that was not developed too much. But very cool.

It's possible to tap a spectrum analyzer into the lnb coax. EB did it, others too. Even a tinysa or SDR like the SDRPlay line with a spectrum analyzer program. A device that covers the l band would work. Nothing that I really do everyday.

Enosat's example. Which an E2 plugin would be very cool. To at least see where transponder "hits" are snagged. Then the ability to target the frequency and do a sr scan.
Expecting a bit much from a receiver. Trying to probably compare what I've seen that a DVB card in a pc can do.

It's sorta' nice to feel like since the issues are perhaps driver related and my Edision is perhaps not actually taking a slow trip "South".
TNAP pulled the dvbsnoop plugin in whatever form it was. And definitely not being a command line, terminal-fluid person. I looked up a dvbsnoop GUI plugin for E2. Came up with blanks. I figured that since the TNAP Mod driver was supposed to target low sr transponders that it was good for feed hunting. Maybe it's the blindscan plugin that wasn't tailored for the different drivers.

I would have to say that a great percentage of my channels are derived from blindscan details and not the transponders in the satellites.xml file.
Matter of fact since blindscanning comes up with frequencies a few MHz different and sample rates a touch different from the packaged satellites.xml in images. I have done it both ways. Built the xml from scratch and/or edited the entry lines reflecting the differences.

Thoughts of a DVB-S2X PCIe card are in the works. Asking around on places like Ricks came up with a lot of different opinions. Some out of my price range at the moment. Just when you think that you;re the geek. You see frequent posts of wild feeds found all over the arc. Dang!

Satelliteguys has a ton of good folks. Willing to help and go out on a limb. Plus a few daggers thrown when necessary. And it's all good.
Thing is.Nobody here is an "idoit". Some might make 10d10t errors and mistakes. I got my butt ejected from sats.uk faster than a bad Subway seafood sub when a brit constantly jumped in and hinted to a less than his pompous and self proclaimed I.Q. of myself. "Ya' shoulda' shut up, ArloG.....ya shoulda' jusssst ignored him". Haha. New VPN node, new name, new location. And learn to just ignore the bad ones. Right!?
we're sorry. there is a problem.......you've been banned.
