I made myself a homemade 2.14m dipole antenna yesterday and a weather satellite called NOAA-19 passed my house 15 minutes ago.
with some coax cable and an SDR dongle I've managed to capture some signals from it and decode them with WXtoImage.

here's some pics:

I'll get some pics of my setup later today

yeah I'm gonna be building an omnidirectional antenna and a satellite dish soon for higher gain

can u post pics? ive never tried this before and it sounds/looks hella cool

crunk� · July 11, 2014, 01:45:43 PM

kickass, can we get pics of the antenna itself

Aide33 · July 11, 2014, 02:07:46 PM

sdr dongle itself:

the mcx to coax cable that I bought on amazon:

cable going out the window:

the antenna is a pretty standard T shaped dipole 2.14m across to receive on 137.1mHz
this antenna is temporary t'ill I build one with higher gain

splitter/transformer:

and the copper cables split on to the each of the structural pieces of wood:

the software used: SDR# and WXtoImage

OP is gonna hack the world

OP is an alien, everyone run!

Actually, this is pretty cool.

that's pretty sweet yo. can't wait to see how you'll improve this later on.

the master plan behind this is I'm gonna make my own software and attach it to a tilt/pan assembly so I don't have to rotate the antenna as the sat passes

oh and NOAA-18 is about to come over the horizon expect more stuff

wait, did you receive SSTV signals?
