frequency band (LVHF) it is recommended that the same line-of-sight (LOS) siting considerations
be applied as when operating in the VHF or UHF frequency bands.
5-1.6.2 Antenna Installation:
Connect the LVHF antenna to the type “N” connector on the front panel. Route the
gooseneck portion of the antenna base so the antenna is oriented vertically. Satisfactory
performance is achieved with the
LVHF antenna and the VHF/UHF antenna mounted on the
URC-200 (V2) at the same time. However, the unused antenna should be removed for optimum
antenna performance.
5-1.6.3 Selecting LVHF Frequencies:
Press
the [FREQ] key (keypad [1]) to select the frequency entry mode. To select a frequency
in the LVHF band, a zero (0) must be pressed before entering the desired frequency. For
example, to enter 35.6 MHz, pres
s [0] [3] [5] [6] [0] [0].
5-1.6.4 Squelch:
The
30 to 90
MHz band employs a 150 Hz Tone Squelch. To activate the Tone Squelch,
press the [TONE] key (keypad [2]). A lower case “t” will appear at the 100 MHz position on the
display when the Tone Squelch is active, or turned ON. When using the 150 Hz Tone Squelch,
the Squelch Control will not effect the tone squelch threshold. It should be noted that the only
signals that will break the receiver’s squelch, when the Tone Squelch is ON, are those that are
on-channel and are being modulated with a 150 Hz tone that has a sufficient deviation level to
break the receiver’s tone squelch threshold.
If desired, the 150 Hz Tone Squelch may be deactivated, or turned OFF. The lower case “t”
will disappear from the 100 MHz position on the display when the Tone Squelch is turned OFF.
With the tone turned OFF there is no squelching of the white-noise on the URC-200 (V2).
