Hi All

I`v done the calc and I`v found that I need more primary to get the 
system to tune.
OK so adding more primary C is not an option also there is no room to 
add an extra
turn on to the primary, so I built a small inductor out of 14 turns 
of thick insulated
copper wire about 3" dia in the centre is a soft iron core made up of 
ferrous rods.

This plus the primary coil give just over the required inductance.

What are peoples thoughts on this ? method and construction.

Cheers Mike
