I'm getting ideas, and parts, together to allow me to build a small transverter for 136kHz. For the TX low pass filter I'll use either T68-2 or T157-2 (or something on between) toroids as these seem most suitable at up to 30W. For the RX input tuned circuit I still need to find a suitable inductor, preferably tunable. Any ideas?
