With Danphone’s MF/HF Power Sensor, output power and VSWR can be measured, displayed and stored on the Futronic MKll. The MF/HF Power Sensor is connected between the transmitter output terminal and the antenna tuner. Futronic MKll will display the PEP power and VSWR, when the transmitter is modulated by means of Danphone’s multi-tone Audio Reference. The Audio Reference is not required, when measuring output power on DSC.
