Feature

●Automatic transmitter and reception switch: The speed of the response is very short due to the RF trigger switching in high-speed detection mode achieved in interrupt mode. This automatic trigger eliminates the need to connect PTT control lines to automatically switch the amplifier to transmit mode by input signal
●Automatic switching of LPF filter: The frequency detection module designed on the circuit, can be automatically switched to the corresponding LPF filter according to the frequency of the radio frequency signal input by the radio station
●CW Semi-Insert Mode: Even if the station does not have CW semi-insert mode, the amplifier has adjustable semi insert mode function. Double click the multi-function button to switch between semi-insert delay times, delay range is 100ms-3s
●Real-time display of power and stationary wave: Dynamic bars are added to allow you to observe the output power better. When the stationary wave exceeds 2.0 or the power exceeds 55W, the power amplifier will automatically turn off and the display screen blinks and displays the value that triggers protection, and the buzzer will alert you
●Frequency Display Function: Displays the current transmission frequency in real time with 100KHz accuracy
