[App_rpt-users] audio for direct VCO FM

[David McGough]

Steve,

The first thing I would try is to locate some hams closer by that have 
already obtained a pallet full of surplus radios. If not in NZ, perhaps 
Australia. At least that should be cheaper shipping than coming from the 
North America--I think.

If that approach doesn't pan out, perhaps some hams here in the USA would 
be willing to help by obtaining several radios, packaging and shipping as 
freight. In this scenario, only a few completely assembled radios might be 
included, with the remaining hardware stripped down to just printed 
circuit boards, excluding heavy chassis and heatsinks, to reduce shipping 
weight.

Anybody else got any ideas about economically getting radios to NZ???
