RF actuated LED Tx indicator for the uBitx and other QRP rigs https://stream.echo6.co/videos/watch/5798a8f4-64bb-4c3a-91a7-a58fa3c6899f An LED that tells you when you're transmitting is nice but you can do better. Making it RF actuated gives you more information about your signal, such as whether RF is being put out or if your microphone is working. Borrowing from ozqrp.com 's MDT transmitter I describe a simple indicator suitable for the uBitx and other HF QRP transceivers.
