! # !! Field !! Type !! Description
|-
| 1 || <code>site</code> || [[SimTX API/Data types#SessionSite|SessionSite]] || Where the receiver is: a [[SimTX API/Data types#StationBinding|StationBinding]] or an [[SimTX API/Data types#AdhocStation|AdhocStation]]. Exactly one member must be set.
|-
| 3 || <code>center_frequency_hz</code> || <code>double</code> || Centre frequency in Hz. Finite and ≥ 0.
|-
| 4 || <code>bandwidth_hz</code> || <code>float</code> || Requested filter bandwidth in Hz. Finite and > 0. Effective value: max(50, min(request, max(24,000, sample rate))).
|-
| 5 || <code>sample_rate</code> || <code>int32</code> || Requested sample rate in complex samples per second, > 0. See [[SimTX API/Receiver session#Negotiation|Negotiation]].
|-
| 6 || <code>chunk_samples</code> || <code>int32</code> || Requested complex samples per [[SimTX API/Packets/IqBlock|IqBlock]], > 0. The server decides; see [[SimTX API/Receiver session#Negotiation|Negotiation]].
|-
| 7 || <code>noise_figure_db</code> || <code>optional float</code> || Receiver noise figure in dB, finite and ≥ 0. Unset: the bound rig's noise figure, otherwise 6 dB. 3 to 8 dB is typical.
|-
| 8 || <code>timestamped</code> || <code>bool</code> || True: every [[SimTX API/Packets/IqBlock|IqBlock]] carries the UTC instant of its first sample. Works with or without an account.
|-
| 9 || <code>solo_transmitter_id</code> || <code>string</code> || Moderator feature. Leave empty. A non-empty value needs <code>monitor.any</code>.
|-
| 10 || <code>tracking</code> || [[SimTX API/Data types#Tracking|Tracking]] || Track a target from the start. See [[SimTX API/Tracking and pointing|Tracking and pointing]].
|-
| 11 || <code>sample_format</code> || [[SimTX API/Data types#SampleFormat|SampleFormat]] || <code>SAMPLE_FORMAT_INT16</code> (0, default) or <code>SAMPLE_FORMAT_INT8</code> (1).
|-
| 12 || <code>aim</code> || [[SimTX API/Data types#AntennaAim|AntennaAim]] || Where the antenna points when the session starts, for example to reconnect already pointed at a manual heading. Unset: the antenna's stored heading. See [[SimTX API/Tracking and pointing#Start pointing|Start pointing]].
