The UK Decca Navigator transmitters shut down for public use this weekend.
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.

Have a go Walter and I hope you can get a team together. Besides good RF
engineers to retune and manipulate the transmitters you will need some ACE
operators, they seem scarce on LF.
