You wont be able to do real experimentation unless there are a spread of operational stations for reports etc. As to 1.4H coils try measuring the inductance of some old audio transformers, and mod transformers, maybe the odd C-core power transformer. I think you might find them in the right kind of range, though you may need an air gap (??) I have a torroidal line transormer (100v line..... I think its called) from an old slave audio amp that looks about right, and is certainly good to about 40kHz. Insulation could be another problem though !!
