METEOR M2 IMAGES
Saturday, October 18, 2014. Meteor M2 Images using RTL SDR. 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. 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). New QPSK Plug...

NOAA APT Images using M2 Setup
NOAA APT Images using M2 Setup. Sunday, April 19, 2015. Automated setup uses RTL SDR with home brew QFH antenna and a home brew preamp. Audio from SDR# transfered to Wxtoimg using Virtual audio cable. SDRsharp's frequency is controlled by Orbitron DDE client, according to AOS or active satellite. Wxtoimg processes demodulated audio and saves necessary files. For more details visit Link. All Images are manually uploaded, late evening, not everyday. NOAA-15 Ele-67W, 29-April-2015, 5:56PM IST (12:26Hrs UTC).

Ultimate QRSS U3
Thursday, May 15, 2014. Ultimate QRSS U3 Transmitter. Kit is developed by Hans Summer. It can transmit multi mode like QRSS, FSKCW, DFCW, Hell, DX Hell, Slow Hell, FSK, CW, CW ID, WSPR, WSPR-15, TX and customisable patterns. Thanks to Hans for developing. Wonderful kit, its very r. And I would recommend to buy rather than building one. I decided to build myself as I had most of the parts in my junk box, left over components from earlier rf projects. I had already built. But wanted to make a. Posted by Ma...

Self Balancing Robot
Thursday, May 15, 2014. 2 Wheel Self Balancing Robot (SBR). I decided to try 2 wheel self balancing robot. This is my experimental Self Balancing Robot based on Arduino. And it needs lot of work to be done on the software. I am not an expert, but trying to learn topic of my interest. SBR uses Gyro accelerometer MPU6050. 2x BO DC motors. Motor driver L293D and a 5v cellphone external battery charger. Settings and other(oscillation) issues. There are few hardware problems like motor backlash. NOAA APT Imag...
