OW-0003LIVE
Placeholder intercept until this node files its own. Two open-source stacks, both GPLv3, both inspectable end to end.
GNU Radio is not a radio. It is the DSP graph: capture, filter, demod, decode, sink. Official site and the GitHub repo are the primaries. If a vendor white paper disagrees with the tree, the tree wins.
SatDump sits one layer up for space: generic satellite data processing over RTL-SDR, Airspy, HackRF and similar. Live pipelines, baseband record, weather/LEO downlinks. Primary is the SatDump/SatDump repository (GPL-3.0), last pushed 2026-09-13.
Why it is on this wire: Ka and LEO work starts at the dish. Before mapping gateway farms we need a receiver chain we can read. This packet is the open slot filled with someone else’s primary. Orderwire notes come next.
