McPhee Aviation began selling gliding instruments in Australia in 1971. In the mid '70s we imported about 200 low power drain radios, introducing VHF radios to gliding in Australia.  For the past 25 years we have been the principal supplier of specialised soaring instruments for Australia, including Winter of Germany and Cambridge Aero Instruments of USA.  We also supply the Australian made Microair 760 transceiver which mounts in a 57mm instrument hole and has interesting features not provided on any other transceiver.  Planned for early release is the latest generation Mode S transponder.
