    Smallest EMWIN antenna

    I watched it live. It was a very good presentation.

    Smallest EMWIN antenna

    Honestly, at the rate they're going, it's going to be very late 2017 or 2018 before GOES-R takes up position as east or west. So I'm not even worrying about this for now. Ultimately though, I think it's going to be hit or miss whether the Verizon signal creates interference. If you're not too...

    Smallest EMWIN antenna

    Nah, I wouldn't waste the money. My DIY EMWIN setup with the grid dish breaks down like this cost-wise: 1) 2x TP-Link Grid Dishes: $89.54 ($44.77 each) - http://goo.gl/YP5beK 2) LNA: $150 - http://www.downeastmicrowave.com/product-p/1691lnah.htm 3) AirSpy R2: $169 (on sale atm) 4) Decoder (from...

    Smallest EMWIN antenna

    Thanks! Shocker. I'm going to go ahead and call it. We won't see GOES-R take up a east or west position until VERY late 2017 or early 2018.

    Smallest EMWIN antenna

    Btw, I have successfully moved from receiving EMWIN to receiving LRIT! Screenshot attached. Thanks to everyone here in this thread for the help with the dish/signal issues and thanks to Joe for the decoder! The only "problem" I'm having at the moment is with xrit2pic not automatically...

    Smallest EMWIN antenna

    What angle should I be aiming for? I've played around with it and it doesn't seem to make a difference in the signal (which is weird).

    Smallest EMWIN antenna

    He's been traveling this week but when he gets time he's going to send me a copy of the LRIT decoder to try. So hopefully I'll be able to obtain some LRIT images myself fairly soon! I remember those days! It was better than nothing but sometimes they were barely useful. I don't even want to...

    How do the current GVAR images compare to the current LRIT images?

    Smallest EMWIN antenna

    I'm actually rather surprised at how sturdy it seems to be. We had some 20mph wind yesterday and it didn't budge a bit. I figured the dish would at least wobble a bit on the horizontal plane but nope, nothing. Since it's just temporary, nothing is actually attached to the house, nor is there...

    Smallest EMWIN antenna

    In addition to my primary setup with my 1.2m dish, I decided to build one of the antennas Tim designed using the two 2.4ghz grid antennas and compare the two. Honestly, I'm quite surprised by how well it performs. I've attached two screenshots. One showing the antenna and one showing the...

    Smallest EMWIN antenna

    Eh, it'll be at least a year before the changeover happens and that's assuming all goes well with the launch and assuming everything works during testing. So I'd go ahead and get your setup going if you find the time.

    Smallest EMWIN antenna

    Definitely seems to be working for EMWIN. I can't wait until Joe/USA SatCom makes the lrit demodulator available! Nope. A microbud will not work. I've never heard of anyone getting a reliable signal on anything under ten feet. That said, you could probably get a signal on a eight foot dish...

    Smallest EMWIN antenna

    I'd say it also depends on whether you're connecting to goes east or west. I know they haven't said which position goes-r will replace (east or west) but I'm leaning towards east. This is why: http://www.goes-r.gov/spacesegment/glm.html The east position has a much better view of CONUS and...

    Smallest EMWIN antenna

    Same here. I've been tempted but with the coming changes it just didn't make sense. They are HORRIBLE about replying to emails. I'm honestly not sure how they are still in business since they never reply to sales questions. I can sort of understand why they want to combine them. The LRIT and...

    Problem Solved! Turns out I was off by just a wee bit on the center frequency.

    Smallest EMWIN antenna

    Eh, I don't have a clue what's going on. I've checked the dish and all seems to be okay. The dish is still aligned. I know this because I marked the mount with a sharpy when I had it peaked and all the lines are still lined up perfectly. The LNA is also working as it should. The odd thing is...

    Smallest EMWIN antenna

    Well, I had this working with viterbi down to around ~200 and then I was an idiot and upgraded the computer (more ram/bigger hdd) and reinstalled windows. Something seems to now be off. Can anyone spot what I'm missing (screenshots attached)? The dish has not been touched.

    Smallest EMWIN antenna

    Well, I don't want to speak too soon but I think I might have a usable signal now. See attached photo.

    Smallest EMWIN antenna

    Have they (NOAA/NASA) decided what they're going to do in regards to the new HRIT service and the frequency? I haven't heard anything and can't find any new information. It seems kind of odd that they're leaving this up in the air this close to the launch.

    Does anyone have a recommendation on a power supply that will hold up more than a couple of months?
  21. doubleohwhatever

    Smallest EMWIN antenna

    Well, I thought I was getting somewhere this time. I had a nice strong signal and could clearly see the datapackets. Then after coming back from dinner everything was dead (LNA, Downconverter, etc). I suspect the power supply. So now I'll be waiting on a new PSU to arrive.

    Btw, I meant "LNA" and not "downconverter" in my last post. Also, I stumbled across this: http://slideplayer.com/slide/5811897/

    Smallest EMWIN antenna

    Same here. Got busy with other projects. I got my downconverter from Down East Microwave last week. I was hoping to get outside today and install it but it's 94 at 97% humidity right now. Not happening. Maybe another day this week.

    Smallest EMWIN antenna

    Thanks for this. I was unable to sign on today. So I have two questions after this: 1) It sounds like the byteblaster service will be shutdown with everything switching to FTP. Is this correct? 2) What are the odds of the grid antenna (even the improved version) working with the new service?

    Smallest EMWIN antenna

    I just have the one from mini-circtuits at the moment. That's why I'm waiting on the one I ordered from down east microwave. I want to use that one as a comparison to the mini-circuits LNA to see if indeed the mini-circuits LNA is not functioning properly like I suspect. Reasonably certain (can...
