EESys Makers of Trans-Ind, the Aircraft Transmit Indicator
Is your transmitter working now? Electronics malfunction at random times. Existing indicators show only that the transmit button has been pushed. Trans-Ind confirms operation of the entire transmit system from transmit button and microphone to radio and all the way through the antenna every time you transmit.
