Tried to download the NOAA18 weather satellite picture with the RTL2832, but the signal didn’t last for very long. Probably need a better antenna which is circularly polarized.
NOAA stands for the National Oceanic and Atmospheric Administration, and their satellites transmit live weather images.
Currently using an outdoor J-pole tuned for around 130Mhz.
RTL SDR (RTL2832) is a low cost software defined radio. You can buy a RTL SDR dongle here http://www.amazon.com/gp/product/B009U7WZCA/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B009U7WZCA&linkCode=as2&tag=youtube0ae9-20&linkId=RR5VUVIXLMIB43M

Hi, thanks! You just need to enable stereo mix under recording devices in
your windows sound properties. WXtoIMG will then use the sound going to
your speakers.
Yes , I use a Realtek dvb-t stick, and because of the high rf interference
in my area – from fm broadcast band and pagers I cant use a vertical
antenna. I use a horizontal 5 element beam for 2 mtrs and I track the
satelites by hand – its the only way for me
Virtual audio cable, or stereo mix both work well. But the virtual audio
cable trial plays audio to say it’s a trial version every few seconds, so
you must use the pay version for best results.
Good luck!
I’m having decent luck w/ gqrx. Usually its simply an issue with signal to
noise ratio because of the antenna and/or feed. It needs a good signal for
it to come out even decent. I crank the input gain through the roof until
the entire background is red and the scope is at the top. I’m not saying
what I’m doing is the ideal way, but I have got some decent pics. It really
helps if you have a circularly polarized antenna, and it needs clear line
of sight of the sky.
I thought it might be because of the circular polarization of the satellite
signal causing the signal to fade in and out on my non circularly polarized
J-pole. It’s not shown in the video, but I did notice after the signal
disappeared it came back for a few minutes before fading out again. I think
a turnstile antenna would be better than a dipole as it is circularly
polarized.
Thanks for the advice. Do you track the sats by hand?
Good job! What do you use to connect SDR# and WXtoIMG ? Masanobu, JA1DAO
Without a decent QFH or Crossed Dipole antenna the signal will be very low
and will fade in and out – even with a decent antenna a preamp is also
needed if you want decent results each time – you may get a few good passes
without a preamp but its gonna be hit and miss for most!
It is built into the program in order to make you buy the full version – If
you do it will go.
virtual audio cable
I use NFM with 34khz filter bandwidth.
Ok in my record area it only states waiting for NOAA 19 at the bottom why
cant I get images from other NOAA pass overs
