I haven't found any info in the forums.
I got the system up and running, and receiving the bird. I decided to get clever and change the name and password. Now I am unable to log in except as 'guest', which is no help. I assume I mis-keyed a letter on my droid keyboard during the user or pwd entry.
Is there a hardware rest on the PCB? Or another method?
Hello, here reporting my new helical antenna, in terms of the measurements I have used this web page: https://www.jcoppens.com/ant/helix/calc.en.php
These are the data that I entered in the calculator of the page:
Design frequency: 1539.87 MHz
Number of turns: 6
Turn spacing 0.19 (wavelengths)
* Bronze square of 140 mm and thickness: 1,5 mm
* Copper wire: 3.8 mm (Thickness)
* SMA Female connector adapter
* 1 Bolt and Thin wood stick to support the spiral and Cable Plastic Zip ties
The signal is more stable, less packages with errors and good values of SNR that although it is not constant at least maintains higher values with a fine pointing, I would like to know your comments and opinions, suggestions ..Here are some photos and screenshots.
Yesterday my Outernet Receiver DIY Kit arrived. I was quite surprised not to find the hardware I had ordered (small board, RTL2832 Dongle, BIAS Injector, LNA and Patch Antenna), but a much larger board and a different antenna. A sticker on the box told to attach it to the LNA Bypass SMA, not to the LNA IN SMA, as this is an active antenna.
Also the cable was missing to connect the antenna to the board. The antenna I had ordered had a cable directly attached according to the picture.
Well being a ham I was able to find fitting connectors to improvise a cable.
Well this is what I did. Then I spent about two hours trying to get any signal form the satellite. I nearly despaired and already feared I got some broken hardware.
I started browsing the outernet.is website, which at the moment is completely broken, dead links wherever you go. Finally I found this:
And this was the solution. It looks like by default, the bypass SMA is not the selected one and the bias tee is not active on the bypass SMA, not powering the active antenna.
After enabling the bypass SMA and bias - bang +5db signal. Not a sigle packet getting lost!
May I strongly suggest to outernet.is to please add a note to the package, on how to enable the correct connector and bias?
Please also fix all the dead links on your website.
Some more question: I would like to use the dreamcatcher for other things too, so I would like to directly access the onboard RTL chip. But 'apt' or 'apt-get' is not installed. So I also am not able to update the software to the actual versions.
I have not found this mentioned on the website.
Any hints on how to do that?
I made a try to install on Dreamcatcher the aprs iGate/direwolf example.
It was evident the steps, but finally, when I start the direwolf prog, a got the error:
rtl_fm: symbol lookup error: rtl_fm: undefined symbol: rtlsdr_set_bias_tee
It seems, the started rtl_fm version hasnot the code dealing with the bias-tee switching. It is only in a newer version of the osmocom rtl-sdr tools.
In my case, first I instelled the "standard" version of the rtl-sdr tools, with the apt-get install command, and this was the "generally accessible", when I call the rtl_fm.
After, I modified the path to the rtl_fm prgoram, to the extended version, it sarted running whithout error messages.
Maybe the solution of this situation, to remove the "standard" rtl-sdr tools, and make install the version, has link in the outernet doc here:
Happy to help with compiling/testing packages, software, OS for Dreamcatcher. Current job is tech support for a linux virtual appliance running open and closed code software pulling from an in-house repository fed from up-stream repositories plus our proprietary code. I have extensive Linux experience, including on embedded systems, i.e. I have 7 RaspberryPi's running here doing various things. I also have been playing with SDR's for a couple years now and have several configurations and antennas available for testing.
This is the feeling ...in this moment.. Ridiculous website...chaos... etc...
Having installed the rtl drivers on dreamcatcher, I can't get it to show up as a usable device in any of the windows based software. Plan was/is to use it with SDR# in combination with Jaero for L band. At this point dreamcatcher happily sits in device manager as an rtl device but not much more. I've had sdrx running in this manner but am struggling with dreamcatcher. Any ideas?
(P.s) I haven't gone through and installed anything onto an sd card as didn't seem relevant
I have the CHIP/Skylark version of Outernet. Is it possible to install the new dreamcatcher distro? Has anyone successfully done it? Will Skylark be discontinued?
I followed the WSPR doc instructions on my orange Pi PC2 running Armbian.
I plugged in a RTL-SDR.com version 3 dongle and attached the antenna connection to my 3 foot high 8 Wire Discone antenna.
10 minutes later I was picking up a WSPR signal from Alice Springs Australia. Like 3000 km away from Philipines.
I was stunned. But I checked on the WSPR net website and there was the confirming line on the map stretching from Australia to Philippines.
My question is does these instructions which allow for Q mode (basically a underclocking of the dongle) only apply to the generation 3 RTL-SDR dongle with a TXCO crystal or can I use a $9 Blue rtl dongle from China and use the PPM correction (-52 in my case) to correct the frequency.
Seems to be always booken lol...
The Dreamcatcher is on and working great.
But I have yet seen myself on the maps.
I'm in Seattle, Washington., USA.
And I'm rocking over 9.1bB and Locked, 0 errors..
Just curious if the page is broke or not... It seems to be the same image all the time .
Anyhow. Have a great day
I have followed some instructions from Sept 2016 on installin Outernet in a box.
I have installed it onto Ubuntu 16.04lts
I can demod=presets update but I can not do the "demod-presets apac"
The install went fine but I get the following error.
george@george-Aspire:~/outernet-linux-lband-master$ sudo demod-presets update
[sudo] password for george:
Fetching update from https://raw.githubusercontent.com/Outernet-Project/outernet-linux-lband/master/presets.sh: OK

how might one go about lowering the Freq. Offset?
mine is pushing -3500 +or- 100
hey all i got a new DreamCatcher, OS on it, WFI all ready to go... Uhh i been looking how to get outernet streams into it... but cant find anything but:
so do the boards sold by outernet, actually receive outernet?
Im VERY technical, but damn man... nada on the site...
Skylark 4.4 images for Dreamcatcher board (V2.03) are up on archive:
There are two images, one for passive antenna systems (the metal one) and the other for the active antenna:
Please use the correct one for your setup. Make sure you read the Readme completely.
Rest of the usage is standard skylark, you can find that manual here:
