I tried decoding new Russian weather satellite “Meteor-M №2″ broadcasting at frequencies of 137.1 and 137.9 in the LRPT format with an Image resolution of 12 times greater than the aging analog NOAA APT signals.
Setup uses RTL SDR with E4000 tuner chipset, home brew QFH Antenna and a homebrew preamp. There is heavy interferences on 137 Mhz from an unknown source, in-spite of it I have managed to decode some of the images, as and when time permits.
Most of these images were decoded using GNUradio (Ubuntu flavour of Linux) installed on flash drive with persistent mode and booted through it, special thanks to Raydel Aberu Espinetm CM2ESP for it. See details (PDF file).
More info is available here. Track in Real time here.
My two page setup was published in GEO MAGAZINE'S QUARTERLY ISSUE, DEC 2014.

My RTL Setup.
Through multi way switch, I can connect RTL directly to antenna or through 137 MHz preamp or use HF up convertor. It has its own power supply reducing interference from pc or its supply. When using my Samsung tab this prevents taxing Tab's battery.

Meteor Images from above setup.
White band in the images is due to glitch on the RAW HRPT to LRPT JPEG compressor system on the satellite.

Another interesting image form defunct Meteor M1, note its imaging instruments are pointing away from earths land mass, hence you can see earths curvature and space.
