Setting up a receive system for the Korean GK-2A (GEO-KOMPSAT-2A) geo stationary weather satellite

I have a dish being used as a garden which is 1.2m diameter

Quorum Communications supplied me with a downconverter for 1691MHz in 1994 for review and testing, I will dig it out of the junk box and see if I can get it going using the Linux software supplied by sam210723


Here is the garden dish...…...

Here is the refurbished dish...……..

Feed constructed from coffee tin, PCB interface plate to which the can is soldered and PVC pipe fittings for feed support

The finished dish installed and aligned to the satellite...…………...

The downconverter outputs 1691MHz at 137.5MHz

GK-2A LRIT Frequency:1.69214 GHz

Thus the output frequency should be 138.64MHz

The following image shows the signal being received at 138.650MHz. The downconverter has a noise figure of 0.97dB and a gain of 24.5dB

The SNR of the signal in SDR# is around 16.5dB

Now to set up the Linux decoding software.

To be continued...………………………….
