 ## Simulated transmit
 
 `--simulate-tx` runs the offline generator through the Soapy-oriented simulated backend path and writes an IQ-style artifact to disk.
-This is the current closest no-hardware stand-in for the future transmit pipeline in the main application path.
+The current summary includes backend, input source, frequency, and configured output sample rate.
