1-8 AVAILABLE OPTIONS
Various options are available for purchase to extend the URC-200 (V2) frequency range or
change the tuning increments or channel spacing.
1-8.1 30-90 MHZ OPTION
This option adds frequency range of 30-90 MHz to
the URC-200 (V2). This option is for FM
only in both receive and transmit modes. Plain or cipher text types of signals may be used. See
Section 5 for a detailed description of this option.
1-8.2 400-420 MHZ OPTION
This option extends the UHF frequency
range of the URC-200 (V2) to 420 MHz. In 400-420
MHz region this option is for FM only in both receive and transmit modes. Both plain text and
cipher text signals may be used in 400 to 420 MHz
frequency range. See Section 5 for a detailed
description of this option.
1-8.3 ECS-8, 8.33 KHZ OPTION
This option allows 8.33 kHz tuning in the
VHF/UHF bands, and user selectable 8.33 kHz
receive channel spacing in the 117.9750 to 136.9750 MHz band.
It also allows the operator to
place the radio into Aviation mode, which restricts the operating
frequency range from 117.9750 to 136.9750 kHz, with tuning increments of 25 and 8.33 kHz.
Channel spacings of 25 or 8.33 kHz are assigned automatically by frequency, following the ICAO
standards for frequency entry.
This mode also restricts modulation to AM, and allows PT only, disabling the CT feature of
the radio.
