Can these antennas be cascaded eventually to increase speed? I realize hardware and software would also have to be developed as well.
Kind of. It would require two independent channels with a playout server that split the broadcast. The receiver would have two internal radios, but only one antenna would be needed. Itās definitely something we have talked about.
The day that you can pack a few radio live streams on outernet is the day that i will be dancing around for the project and i think that day is coming sooner than later too
Nice info to hear. My chip died but count me as in line for the new hardware.
Hey nice call sign!
My Dreamcatcher 2.03 died in the rain. Itās a wall decoration in my shack now since the hardware is obsolete for Outernet.
I look forward to the new DreamCatcher 3.01 hardware too.
Itās really no surprise that thereās lots of hams here. Hopefully, there will be many more ham applications on Outernet beyond APRS.

Hello
It is very gratifying to hear that outernet are returning to the Ku band
Do you know this antenna?
and I have many questions ā¦ ,. ,.
-The old outernet lighthouse will work with this new bet?
āAlso the Tuner dvb-s2 hdstar geniatech?
āAny other STB linux dvb-s2 ???
-to South America which satellite have you contemplated? 113w?
-any new strategy for content on the network?
thank you very much for keeping and surviving with this exciting project for so long
as soon as the data flow is available south america I will be testing
edit1:
-Dreamcatcher 3.01 only will have 512 MB RAM , why not 1gb or 2gb ?
- which processor will you use for Dreamcatcher 3.01 version ? AllWinner A13 SoC ???
Itās an interesting flat antenna. Itās not clear if the LNB is DRO (dielectric resonator oscillator) or PLL (phase locked loop). Itās my understanding that DROs, while inexpensive, have very poor frequency stability and are suitable only for the reception of wide bandwidth carriers, such as satellite TV. From what I understand, the new Outernet will be a narrow-band SCPC signal. This will require the frequency stability that the PLL type LNB.
@Syed will have to answer the rest of your questions.

I have taken that antenna apart. Itās a really unusual array of little single-turn helices. At that $35 itās too expensive for us.
No, the old Lighthouse receivers wonāt work, as we are not using DVB-S.
PLL LNBs are the cheapest route on the market, as the ICs are so highly integrated now.
Donāt forget, the Lighthouse can run a version of Wetek Play (http://kodi.wiki/view/WeTek_Play) that makes it a Kodi (kodi.tv) receiver when connected to the internet. Ken

i already use wetekplay 1 fot pirate satellite tv . . . . . .and pirate iptv on kodi. . . . . using https://libreelec.tv ā¦

so, not using dvb-s/s2/s2x or scpc on vsat ACM/VCM?. . . . .but you are looking for satellites of that class.
Another mystery that only the reverse engineer could answer?
āthe idea of the antenna is to see designs and explore one, more DIY, another type of approach . . . . .
-Dreamcatcher 3.01 only will have 512 MB RAM , why not 1gb or 2gb ?
- which processor will you use for Dreamcatcher 3.01 version ? AllWinner A13 SoC ???
āany new strategy for content on the network?
(this is for me the reason why the first approach to the outernet Ku fault)
Iām looking forward to the DX Cluster being considered.

@kenbarbi @Konrad_Roeder As active and vocal community members, Iād like your feedback on EchoStar-9 vs Galaxy 28. By no means is this discussion limited to Konrad and Ken. Everyone is welcome to chime in.
The reality is that one beam is not going to be ideal for everyone in the country. Right off the bat, we are looking at 121W vs 89W. On the East Coast, weāre looking at an elevation of 21-degrees for ES9, whereas G28 is 21-degrees for the the Northwest.
EchoStar 9 at Satbeams.com
Galaxy 28 at Satbeams.com
ES9 has a 27 MHz transponder. That means that the power available, EIRP of 48.3 dBW, is spread across less bandwidth, which means we get more bang for the buck. You can also see that ES9 provides full coverage of Mexico, which could be useful for earthquake warning systems. Guatemala is also fully covered with a power level that is similar to the US.
G28 has 36-MHz transponders with most of the coverage area under 49 dBW EIRP. This difference in power and transponder bandwidth comes out to about 15kbps worth of SNR. Thatās the difference between being able to provide streaming audioā¦or not.
No decision has been made yet, but Iād like to make one very soon. I canāt make everyone happy, but I will listen to all of the feedback. Looking forward to your thoughts.
First of all, is one contestant Echostar 9 or is it Galaxy 23? For the discussion that follows, the name should be clarified for all, Galaxy 28 of course is the other contestant.
EchoStar 9 and Galaxy 23 are the same spacecraft, but the C-band is operated by Intelsat and they call their side of the house G23.
Just curious: What Beam will be used for Europe? Astra?
Europe hasnāt been fully explored yet, but NSS-9 is a possibility.
My mistake. I meant NSS-7
As you would expect, I prefer Galaxy 28 because it gives hi elevation angles within CONUS, and more coverage in Canada and Alaska. On Galaxy 28, Seattle would be about 26 degrees which too is low, however the East coast will be about 43 degrees. That said, these are not the areas of the world needing Outernet service, but they house the āhackers and hamsā that are helping make Outernet what it is, and can best test new services and report back results to Chicago. Iām curious thou, why arenāt you going back to Galaxy 19 where you used to be? Is it too expensive?
The ultimate selection of Ku-band satellites for global coverage is going to involve many birds which should have beams aimed at the areas of the world where the internet disadvantaged reside. You can make the same argument (hi versus low elevation angles) for Forum members in Europe too, but when it comes to Africa and SE Asia/China/India, those satellites need to reach the people who would most benefit from the service. Ken
There is not a substantial cost difference between G-19 and G28. But there is a substantial difference in power level. You can see that most of the country is under a 46 dBW contour. That 3dB difference is substantial, as it directly impacts SNR and bitrate. G19 does have the best coverage , but the energy is spread across a wider area.
