I have the hard-to-find TCU for the Swan 240 for sale. This unit matches the 240 and includes a speaker, remote VFO, calibrator, and VOX. There is also space inside for mounting the power supply (not included). Electrically it's all there, original knobs, cosmetic condition is "Fair" due to some missing lettering. Price is $100 plus shipping. Thanks and 73, Bob W9RAN
