Reports from Reddit and Twitter are in that the recently launched Meteor M2-2 weather satellite is now functional and broadcasting images at 137.9 MHz. A few people have noted that the reception quality appears to be better than the older satellite.
Thank you to Happysat whose also provided the following information that can be used to receive the images. It appears that a slightly modified version of LRPTDecoder is required:
This version of LRPTDecoder was used to test/debug OQPSK with Meteor M-N2-1 in 2014, it will work on Meteor M-N2-2.
The ini file attached in the archive is processed manually from s files.
Buttons 72K and 80K respectively for the modes “without interleaving” and “with interleaving”.
Also in the archive there are examples for other modes.
Transmissions on LRPT with a OQPSK Modulation are expected tomorrow on most probably 137.900MHz.
Make sure you have version 1.9 of the Meteor QPSK Plugin running in SDRSharp.
