Re: LF: VLF in NA, PVC coil bodies/VLF converter

[jcraig@mun.ca]

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).
