StationImpactList is an interference analysis for moderators. On a moderation session the server sends it right after the StationList that answers a ListStations. It ranks transmitters by how much they affect receivers, which helps to find jammers and badly configured stations.

Definition

message StationImpactList { int64 request_id = 1; repeated TransmitterImpact impacts = 2; }

Fields

#	Field	Type	Description
1	request_id	int64	The ListStations request_id.
2	impacts	repeated TransmitterImpact	One entry per transmitter, highest impact first.

#	Field	Type	Description
1	session_id	bytes	16-byte transmission id.
2	callsign	string	Callsign.
3	address	string	Client address.
4	frequency_hz	double	Carrier frequency, Hz.
5	modulation	string	Modulation name.
6	power_watts	float	Power, W.
7	occupied_bandwidth_hz	float	Occupied bandwidth, Hz.
8	impact_score	float	Largest spectral overlap with any receiver's passband, percent (0 to 100). The list is sorted by this value, highest first.
9	affected_receivers	int32	Receivers whose passband the transmitter overlaps significantly.
10	nearest_receiver_km	float	Great-circle distance to the nearest receiver, km. NaN when there are no receivers.
11	reasons	string	Human-readable notes, such as an overdriven amplifier.
