It's been a while since I've heard TUK on 194 kHz from Nantucket. I have found one web reference to its being out of service: http://www.iprimus.ca/~hepburnw/dx/twb.htm I found another that implied that the shutdown was permanent. Does anyone have any info on this? TUK was a useful signal reference for the east coast guys. John Andrews, W1TAG
