SECTION 5. OPTIONS
5-1. 30 TO 90 MHZ OPTION 01-P37200N001 TO THE URC-200 (V2) TRANSCEIVER
5-1.1. GENERAL INFORMATION
This option provides the 30 to 90 MHz (LVHF) band to the
URC-200 (V2) Radio Set. Many
of the operational features in the 30 to 90 MHz frequency band are the same as in the VHF or
UHF frequency bands.
5-1.2. FEATURES
5-1.2.1 Frequency Range:
The 30 to 90 MHz range of frequencies resides in
the Low VHF
(LVHF) band of frequencies.
The LVHF frequencies on the URC-200 (V2) has a center frequency tuning increment of 12.5
kHz.
5-1.2.2 Tone Squelch:
Normally the URC-200 (V2) in the LVHF band will
use a 150 Hz Tone Squelch which is
compatible with other radios in this band of frequencies. If desired, the tone may be turned OFF,
however, “white-noise” will be coming from the speaker.
5-1.3. LIMITATIONS
5-1.3.1
Modulation:
The URC-200 (V2) using the 30 to 90 MHz option will receive and transmit FM modulation
only.
5-1.3.2 Carrier-to-Noise Squelch:
The carrier-to-noise squelch, which is set by the Squelch Control when the URC-200 (V2)
is
in the VHF or UHF frequency bands, is effectively disabled in 30-90 MHz band.
5-1.3.3 Select Meter Mode:
The front panel display signal strength meter and power meter do not operate when the
transceiver is in the 30 to 90 MHz band.
5-1.3.4
UEC-120/220 Remote Control Optional Accessory:
Use only the UEC-120/220
Remote Control Units when operating the URC-200 (V2) with the
30 to 90 MHz Option. The optional remote control accessory, UEC-100/200, was designed only
for
the VHF and UHF frequency bands. The UEC-100/200 will not operate in the 30 to 90 MHz
(LVHF) frequency band and, therefore, cannot be used with the URC-200 (V2) when using the
LVHF band.
5-1.4. SPECIFICATIONS
The following specifications pertain only to the 30 to 90 MHz option
within a URC-200
(V2)
transceiver.
