ATV COMPONENTS

Wayne Griffin, ZL1UJK

In addition to supplying PC boards, I often get enquiries from Hams, constructors etc. wanting to know where to obtain ICs, components etc. that are rather special and may not be available in their town or city. Here is a typical list of items often asked about that I now carry stock of in limited quantities.
