The RX sensitivity at 4 kcs is a lot less than 9 kcs therefore it might
appear a better choice but one would need to be convinced and more research
is needed.
I prefer to go the other way up to say 12 kcs and contend with the static by
improving the TX ERP and improving RX antenna etc.
Some cannot manage to put out a decent signal on 137 or 500 kcs never mind
VLF, DREAM on, go to church and think Miracles or Impossibilities.
