Some old radio manuals
This is a collection of manuals for some old (1960's vintage) radio equipment, formerly
used by the (Australian) Dept. of Civil Aviation (DCA). Typically the sets were installed
in airport control towers, & provided ground-to-air and ground-to-ground services.
Ground-to-air used VHF, amplitude modulation. Ground-to-ground used HF, single sideband.
Note: The schematic drawings are too large for my scanner, so they have been taken in
"slices". Where possible, the slices have been recombined
(using Autostitch).
Where this was not feasible, the slices are retained, with names such as
part1, part2, etc.
