A message from Eric GW8LJJ regarding future orders (December 2016):
"Judging by the number of enquiries I still receive, homebrew is far from dead. I am happy to continue to support the kits as far as possible, but some key parts are now obsolete and it's only a matter of time before all supply channels are exhausted. Before you order anything please email me to check availability and pricing."
