Anyway because the FunCube Pro doesn't display as much bandwidth across the scale the signal looks huge and it's much easier to see. If you look at the pic above you are at 1800000. For this reason I use a FunCube Pro Dongle usually which has an input rate of 192000. That's not very wide and will be tough to see your signal. Notice the gray width around the red vertical line below the 5 in the picture below.
Mine just records to my Home Directory (/home/john). Set your filter width to about 40K, your mode to Narrow FM and figure out where you are recording to. There should be no signal until you get it locked in. A generic dongle typically looks something like this and typically the defaults are okay. Your mileage may very depending on what device you bought. Open GQRX and configure and select your SDR dongle here under the Device drop down. You'll need it for both programs.īefore you grab the antenna open GQRX and set the frequency from information you get in GPredict. (Same with WXtoIMG) Google up your latitude and longitude. Before GPredict will work for you, you have to set your location. Then you have a rough idea where to point the antenna. It will also populate on that globe and show you where it comes into acquisition. If you look in the upper right corner it will tell you NOAA 18 is coming in 8 minutes and 22 seconds. GPredict - This is optional but it shows you when the satellites are a comin'.
Wxtoimg problems install#
Sox install with sudo apt-get install sox from a command line in Linux Hurricane Irma and Jose, September 10th 2017 The price is OUCH but if you want grabs like this, you'll pay the price. You can make one for almost free but you need something tuned to about 137 MHz. You can get these on eBay for a few bucks.Īn antenna. I only picked it because it was pretty cheap.
Wxtoimg problems plus#
Plus I'll say this about using a handheld antenna and doing this in the way I describe below.You get better results! I think my grabs look as good as anyone's.yeah there are some guys with stationary setups who crank out better stuff but ask them how much they spent.Ī laptop running Linux (or Windows, but I hate Windows)Īn SDR dongle (any one will do) Try this one. This whole evolution for me is about understanding satellite orbits, azimuths, elevations, doppler shift, etc. YOU DON'T EVEN HAVE TO BE THERE OR DO A THING. IF YOU HAVE A STATIONARY ANTENNA SUCH AS A QUADRIFILAR HELIX ANTENNA (QFH) IT WILL DO ALL OF THIS AUTOMAGICALLY IN A PROGRAM CALLED WXTOIMG. LET ME STATE FOR THE RECORD HERE THAT I'M DOING THIS THE HARD WAY. It is an Automatic Picture Transmission (APT) signal that is somewhat easily decoded. Most of the pics you see on the nightly weather are from NOAA satellites. Lahey on The Trailer Park Boys and you'll understand fully.Īll day, every day three operational NOAA satellites are buzzing overhead transmitting data back to earth. If you wonder why I add in "and shit" on a lot of my web page titles watch Mr.
