WebDec 30, 2024 · I am building the T/R switching circuit for an HF linear amplifier covering 80m band to 20m band. The current circuit takes a potential-free contact from the exciter and use this contact to turn on/off the relay. When PTT is pushed relay contacts connect the RF output from exciter to HF linear amp input and output of HF linear amp to antenna. WebJul 27, 2024 · Make sure to set a 15-30 millisecond TX DELAY in the radio. This gives the amp time to close its big open-frame relay before receiving RF drive. Failure to set TX DELAY may result in popping sounds when using VOX, and "hot-switching" may damage the amplifier. In the IC-7100, TX DELAY is in the Set → Functions menu. nottingham city beach
