Abstract:

The ANARC-19 XN-1 Ultra High Frequency Airborne Communication Equipment was designed at the Naval Research Laboratory for use in Naval Aircraft. This equipment uses only seven crystals including one guard channel crystal and provides 876 channels spaced 200 kc apart throughout the frequency range of 225 to 400 Mc. The frequency stability maintained with or - 5.8 kc under all service conditions. All 876 channels are available to the operator at the control box and, in addition, provision has been made for any ten of these channels to be preselected without tools at the control box and made available on a preset basis. All ten preselected channels can be set up in less than three minutes. The power output of the transmitter is greater than 4 watts over the entire frequency range and the receiver sensitivity is 20 microvolts or less. The current drain from the 26.5-volt supply is less than 20 amperes.
