Today's snow storm on a $12 USB dongle

[rbm]

Here's an image downloaded from a NOAA satellite today using a USB dongle, SDRSharp, and WXtoImg

Not bad for a $12 receiver and some 'Freeware'.

Very cool! Anything fancy for the antenna!

The antenna is just an ST2.
But with an LNA-1000 preamp from RF Bay, Inc.

It feeds a total of 32 scanners.

It's the same antenna I used to make the videos I have on YouTube.

The dongle is different though.
It has an R820T tuner chip. (that dongle was used to create the video in the second link.)

Nice! looks like your setup is receiving better than my Dorne & Margolin satcom antenna.

I have to ask, how are you splitting one antenna to 32 scanners?

Hi Mark,

I use two of these for that antenna. Mounted to the back of my computer desk.
(Click on the 'Shack Photos' icon above to see an older photo of the desk)
But, in that case, I'm not using the Holland preamp shown in this photo .
