DSLWP-B1 – how to decode the image

Save the output of the decoder into a text file (e.g. DSLWP-B_10Oct18_1400-1600Z)

Open text file with my DSLWP telemetry parser

Generate the binary file dslwp_ssdv.bin (e.g. http://www.dk3wn.info/files/dslwp_ssdv.bin)

The ssdv program can be obtained from Dani, EA4GPZ here:
https://github.com/daniestevez/ssdv

> $ ssdv -d -D -v dslwp_ssdv.bin dslwp_ssdv.jpg

Great thanks to Bob, N6RFM for the input data :-) Good job!

DSLWP-B1 data

I made some test with different antennas, polarization (best result horizontal) and preamps this morning (08:21 to 10:21 UTC).
Anyway, most of the packets were too weak …

second activation today (13:00 to 15:00 UTC)
– no JT4G beacons, short image transmission at the end of the activation period
