Skylark 5.7 for Dreamcatcher 3

For Europe, you should be using the “Othernet Dual Band” setting with the universal LNB. Be sure to click the “apply” button when changing this.

OK, will have to wait for that LNB to arrive, I currently have the Maverick.

How long did you have your unit running ? It appears you may have received some data. However, dated Jan 1 usually refers to startup events until actual streaming is achieved. With a 70cm dish, the pointing could be very critical, and I would encourage you to keep trying. You may not get best performance with the Maverick 1 on the Europe bird.
Incidentally, you can paste screenshots and quotes directly to this forum.

where do you see me with rx packets?
I start it up and leave it running when I can has been up for maybe 10hrs.
(edit)thanks maxboysdad, in looking now!

I was just noticing in your uploaded page that there were recent packets showing in your diagnostic screen.
It is noted that they say “from file service”, so likely were not received, but from the boot up.

You may look at mine at 136.36.137.45, login as othernet with pw of j7m*2

This release, Skylark 5.7 is the most stable yet. Up for 12 days! On both a Dreamcatcher v3.03 and a Dreamcatcher v3.05. Ken

While I have a copy of the PDF for HW v3.03 it might be nice for others to have an archive folder on the FTP for older hardware revs.
Will you offer a plug-in touch screen in the future as an accessory?
Is that even an option, it looks like there is where to add the risers on the 3.05 PCB.

I had a lockup yesterday after about 3 days of uptime. Nothing of note in the logs, the Nov 16 was the last messages in /var/log/messages and then the beginning of the Jan 1 restart before the time was set:

Signal lock is good, with SNR usually around -11.5. I wasn’t sure if this could be related to a WiFi dropout and am going to try with a USB Ethernet adapter. I tried a Trendnet TU3-ETG earlier which didn’t work, but I have an old Linksys USB100TX which I think will work.
I am using a 2.5A power adapter, so I don’t think it’s power.

It could still be a power issue. Usb voltage spec is 5v, +0.25, -0.6. So a range of 4.40v to 5.25v. I dont know the specifics of this board but a lot of sbcs dont like voltage below 4.8v. Anything lower than that cause problems. Check the voltage coming into the board.

I’ve been experiencing a similar problem, I just haven’t had time to diagnose.

Many of us went through these same problems two years ago when first starting up the version 3.02Q boards. After going through much the same trials you are seeing here, those of us who were monitoring the voltage to the device found that if the voltage drops below 4.95, these odd symptoms begin to present themselves. In almost every case, providing a good power supply that was capable of keeping the voltage from 5.0 to 5.2 consistently without “sags” below 4.95 solved the problems. The official Raspberry Pi power supply was found to be among the better solutions. Many of the inexpensive power supplies that provide “5.0” volts will show a sag to as low as 4.5 within a few hours time of beginning operation. Aside from that, a good USB A to Micro USB cable (not the one that came with your phone) of sufficient wire size also will help.

The following would be useful:
*When to choose active vs passive antenna
*EU vs Americas seems pretty straightforward
*custom :frequency and beamtype settings probably publishing in an appendix in the guide how much offset for each LNB as well as common user tested LNBs
*a guide to using a common offset dish with angles tech drawings describing how the offset works and how to make a plumb line & protractor measuring tool.

Another aid video showing a Dreamcatcher from boot to acquisition of signal inclusing scanning the sky as Syed has described while watching for the RX packet LED(and the tuner web app), both with dish and bare LNB; as well as using popular satellite finding phone and web apps.
I am assuming that one of those inline sat-finder gadgets would work inline between the Dreamcatcher and LNB to speed aiming for both bare LNB users and dish users, has anyone tried this?

@Abhishek …trouble… on one of the dreamcatchers

Hi Ken @kenbarbi ,
Maybe you can include these hints in your great tutorial?
Thank you

I’ve tried to include most that new users might need. What other things do you think need to be added? Ken

@kenbarbi Sorry. I forgot to quote. I meant this statement.

Yes, now I see, Robert. That’s a good addition. I’ll put it in. Ken

@Abhishek here is an idea for the next improvement to skylark…
slow down the flash rate of the pckt (led6 on DC 3.05) by two or three
…or increase the “on” time.

That would make a “brighter” flash during tuning. The current (ver 5.7) has a very short duration
on signal that is hard to see when adjusting the setup.

the packet led is driven in hardware - and exactly corresponds to actual packet reception - at the radio level; the LED blinks even before the software has “seen” the packet.

Its not a simulated blinking driven from software merely as an indicator. Its duty cycle/flash rate thus cannot be changed.

I installed this shortly after it was released but I just noticed today that everything still says skylark 5.6. Is anyone else seeing this?

Your browser probably has the old screen in cache. Suggest you clear your browser. Ken
