This is a collection of 60 air to ground WAV files using sounds from each manned mission arranged in chronological order. Tune into a frequency of 220.410. In addition I have included in the "Doc" folder as an option 28 base CFG files that represent the Mercury era Manned Spaceflight Network (MSFN) sites. 22 ground stations and 6 tracking ships. All "bases" have no details just names and coordinates for map display.
INSTALLATION:
Just unzip the file into your Orbiter main directory.
(The base CFG files in the "Doc" folder will have to be moved manually into whatever custom file you use for your Project Mercury 5.0 install.)
A little tribute to 7 who helped pave the way.
