    1117=== Get the current configuration ===
    1218
    13 This API call is used to get the current configuration of the RF front end(s) with respect to a node or list of nodes. The response will specify the parameters of the TX chain for the node(s) in question. It will show for a given node's {{{rf_port}}}, what {{{antenna}}} would be used if it were {{{connected}}}, whether the power amplifier ({{{power_amp}}}) is on or off, and the lower frequency ({{{f_lower}}}) and upper frequency ({{{f_upper}}}) of the filters.
     19This API call is used to get the current configuration of the RF front end(s) with respect to a node or list of nodes. The response will specify the parameters of the TX chain for the node(s) in question. It will show for a given node's `rf_port`, what `antenna` would be used if it were `connected`, whether the power amplifier (`power_amp`) is on or off, and the lower frequency (`f_lower`) and upper frequency (`f_upper`) of the filters.

    6487This API call is simply a shorthand to easily turn off the power amplifiers for a given node. Keep in mind that power amplifier state is shared between nodes in the same physical location (eg. sdr1-md1.bed.cosmos-lab.org and sdr2-md1.bed.cosmos-lab.org).
