High Frequency Communications System consisting of KRX-1053 receiver/exciter, KPA-1052 power amplifier, KAC-1052 antenna coupler, and PS-440 Control Display
Provides long distance communications in a 200-Watt system
Lighter system components than most HF systems
99 user-programmable channels
Pre-programmed emergency channel at 2.182MHz
280,000 discrete operating frequencies covering the 2.0000 to 29.9999 MHz frequency range in 100 Hz steps
Selective Calling (SELCAL) capability standard (also requires Selcal decoder)
Non-volatile memory stores antenna tuning information across the entire HF spectrum, allowing future tunes to happen in milliseconds
DATA mode for interfacing with data modems or secure voice systems
Enables economical long-range voice communications in Oceanic, Polar and remote land regions
Works seamlessly with the Collins Aerospace portfolio of communications products
The antenna coupler’s dedicated memory holds a list of previous tuned frequencies, which provides fast tuning times and quick channel changes
The antenna coupler uses solid-state tuning to provide greater reliability over analog-based mechanical tuning devices
The HF transceiver operates on frequencies spaced 100 Hz apart in the 2 to 29.9999 MHz band
Enables you to call up 99 user-programmed half-duplex or simplex channels, 249 half-duplex ITU channels or six emergency channels
The HF transceiver mode provides USB, UD, AM equivalent, CW, LSB and LD operation. The 99 user-programmed channels can be programmed to operate in any of these modes.
Uses fiber-optic technology to interconnect all system elements for increased bandwidth, reduced EMI and installation weight
Available with selectable power outputs of 175, 50, or 10 watts PEP (optional 200 watts receiver/transmitter)
Uses BIT for diagnostic testing and monitoring
Control uses diachronic LCD for optimum readability in all lighting conditions
