From KAVAN RC Wiki

ACCESS normally has one inbound telemetry path for each RF link or one link for each ISRM RF module. The Tandem systems are an exception with one TD ISRM that has a 2.4 and 900m section for two RF paths. The telemetry source receiver may change during a flight depending on RF conditions. ETHOS has an RX sensor that displays the telemetry source real-time and data logs the RX sensor data.
