Hi Stefan, Pete and  Johan,

Some lovely coil forms! All that is needed is the wire.  0.4mm is
available here in 30m or 75 kg spools.

Thanks for the encouragement.  I'll keep plugging away in the shack

Johan, I'd like to build your FB VLF converter iand use a 10 MHz LO. L1 C5 and C6 and L2 were scaled for 10 from 4 MHz but a T1 core
is not handy. Is 5 mH per winding satisfactory?

Antipodes quest on LF is off till the far tower is re-erected.
At the moment using the small RL (-7dB).

BTW if you want to radiate a somewhat stronger signal i can recommend
