Most sites have already been sold for other purposes but a few will remain in working order for a few months. I might be able to get permission for an interested group to operate using one of these sites for a limited period during May/June/July. The likeliest one has a 300 ft mast; an extensive ground plane and an ATU coil that could probably be tuned to 136 kHz. Radiation efficiency at 127 kHz is a measured 12% so 8 watts in would provide our legal erp limit. It could also be tuned to go on 72 kHz - it already transmits at 71 kHz. Only a group willing to take on legal responsibility for damage; pay the electricity bill, etc would be authorised. There would be a fair bit of effort needed to retune everything - no engineering support is offered. The excuse might be it's a commemorative station organised to mark the passing of the Decca Navigator system. Special callsign perhaps. Anyone interested? Serious applications only PLEASE.
