Editing SimTX API v24/Packets/TransmitterSessionRequest (section)

== Rules ==
* All 13 required fields must be present, otherwise the connection is closed without a reply.
* Unknown field IDs are skipped. If a field appears twice, the last occurrence wins.
* A single field may not exceed 263,168 bytes, and the field payloads together may not exceed 263,168 bytes.
* Values outside the ranges above, unknown enumeration names and invalid antenna data close the connection without a reply. Values that the table says are ''reduced'' are accepted and silently limited.
* For role 3 (<code>TX_GENERATED</code>) the source type must be <code>WHITE_NOISE</code>; any other source closes the connection. On role 2, <code>WHITE_NOISE</code> produces nothing and the session ends after the 15-second input stall timeout.
* Sample rate rules: the server processes the signal at min(10,000,000, max(sampleRate, 240,000 for WFM)). Raw IQ above 10,000,000 samples per second is rejected with a [[SimTX API v24/Packets/TxReject|TxReject]], as is audio that would need to be resampled by more than 128×.
