Notes in this flowgraph

Upstream sends these frames to a KISS TCP client through satellites_kiss_transport, a Python block: no C++ path, and no TCP sockets in the browser. Print timestamp + Message Debug is the log a KISS client would have printed. Upstream reads BY70-1 here, which does not decode in this runtime, so this uses TRISAT.
