The high fidelity communications environment simulates the following equipment & capabilities:

• KY-58 and KY-100 encryption devices
• AN/ARC-164 (Have Quick Radio)
• AN/ARRC-186 (VHF AM/FM Radio)
• AN/ARC 201 (VHF-FM Radio)
• AN/ARC 220 (HF Radio)
• AN/ARC-6 (Personnel Locator System)
• AN/APR-39A (Radar Signal Detection Set)
• MF-1295/A (Improved Data Modem)
• Radio and IDM Tones
• Aircraft Intercom
• Navigation Aids

The simulation of the encryption devices includes all of the associated cryptographic tones such as preambles and postambles. The IDM passes actual data from a local host computer to a remote host through the simulated radios in the trainer. A Terrain Server is used at every station to enhance the already rich radio propagation environment. The radios also produce a user-specified tone to simulate the effects of jamming.
