Here's a link to that specific part of the guide https://vksdr.com/xrit-rx#keys

Could be a simple `wget` to `nmsc.kma.go.kr` then unzip and decrypt in the background, which still avoids the software actually shipping with the keys

I'm seeing similar behaviour in v1.0.4.11. Data is only output on UDP port 8765 when "decoded and demodulated data" is selected. Nothing is output with "raw demodulated data" selected.

I haven't been able to test HRIT since goesrecv has not been modified for QPSK yet. What is your demodulator and decoder chain? Thanks for the VCDU files, I'll take...

HRIT headers are intact but the JPEG/JFIF headers are broken for some reason. There does seem to be a bigger demuxing issue so I'll take a look at that first,...

Nice! is it a [Dartcom](https://www.dartcom.co.uk/products/lrit-hrit-system/overview) receiver? I have started work on a QPSK DSP chain using GNURadio source for reference. Using LRPT code as well is a good idea! I'll...

Interesting, I thought it looked similar to the [Comtech CDM](https://www.comtechefdata.com/files/datasheets/legacy/ds-cdm700.pdf) modem series, then I found this on the D4L product page:   (Comtech CDM-600)  (ETRA-D4L)

The JPEG headers in these images seem to be malformed and don't have enough info to recover the image data.  They are basically empty when compared to a...

This makes sense as Pillow was throwing exceptions when loading the image. It needs [OpenJPEG](https://www.openjpeg.org/) installed and in PATH to handle J2K. It also mentions they're using J2K in a...

Nice work! I'll look at streamlining that process then integrate it into xrit-rx.
