INSTALLATION
1. Contents
Unpack and inspect your Huracan HR-07-NZ for missing or damaged components. Your Huracan HR-07-NZ includes the following items: Quantity Description 1 Huracan HR-07-NZ Transceiver 1 Dynamic Microphone 1 DC Power Cord with Inline Fuse 1 Mounting Bracket with Hardware 1 Mic Hanger with Hardware Set 1 Operating Manual
2. Microphone Hanger
The microphone hanger may be attached to the side of the transceiver, or any other convenient location. Locate the mounting holes on the side of the transceiver. Use the provided screws to attach the microphone hanger either vertically or horizontally to the side of the transceiver.
3. Mounting
When attaching the Huracan HR-07-NZ mounting bracket to the vehicle, choose a location that will provide easy access to all front panel controls and air circulation to the rear panel. When selecting a mounting location, make sure that there is ample space behind the unit for the cables. Do not pinch, or bend sharply, the power or antenna cables. Do not install the Huracan HR-07-NZ in any compartment that restricts airflow to the air vents under the transceiver or blocks the heat sink and do not install in a location that interferes with the safe operation of the vehicle. Attach the mounting bracket to the vehicle first then mount the Huracan HR-07-NZ to the bracket. If the rear panel is not accessible you may want to attach the power and antenna cable prior to mounting.
4. Electrical Connections
The Huracan HR-07-NZ is designed to work on any 12 - 14.1 volt DC, negative ground, source. The condition of a vehicle’s electrical system can affect operation. A low battery, worn generator/alternator, or poor voltage regulator will seriously impair the performance of the transceiver. Any of the above conditions could result in a high level of receiver noise generation or a substantial loss of the transmitter’s RF output.
Make sure that all of these components of your vehicle’s electrical system are in good condition prior to installing the transceiver.
CAUTION! VOLTAGE EXCEEDING 15 VDC WILL DAMAGE THE RADIO. MEASURE VOLTAGE AT BATTERY TERMINALS, WITH VEHICLE RUNNING, PRIOR TO INSTALLATION!
Before making any electrical connections make sure the volume (VOL) control is in the “OFF” position. Connect the positive (+) red wire of the DC power cord to a positive 13.8 volt source at the vehicle fuse block. If connecting to the fuse block, it is recommended that a switched power source is used so that the power to the transceiver is is connected when the vehicle is off. This will eliminate the possibility of the transceiver draining the vehicle’s battery. Connect the negative (-) black wire to a metal part of the vehicle’s frame, or chassis ground. Make sure that this is a good ground connection.The Huracan HR-07­NZ power cord may also be connected directly to the battery. Connecting directly to the battery has several benefits, the first of which is to maximize RF output. Secondly, the battery is a very large capacitor and will help eliminate certain types of ambient and vehicle noise. If connecting directly to the vehicle’s battery, additional power cable may be required.On runs of 8 feet or less use 14-gauge stranded wire. Use 12-gauge wire on longer runs.
5. Antenna Connection:
The transceiver will operate using any standard 50-ohm ground-plane, vertical, mobile whip, long wire or similar antenna. The antenna should be rated at 50 watts PEP minimum. A standard SO-239 type antenna connector is located on the rear panel of the Huracan HR-07-NZ. Connection is made using a PL-259 and high-grade coaxial cable (RG213, RG58A/U or Mini RG-8 is recommended). A ground-plane antenna provides greater coverage and is recommended for fixed station-to-mobile operation. For point-to-point fixed station operation, a directional beam antenna operates at greater distances even under adverse conditions. A non-directional antenna should be used in a mobile installation; a vertical whip is best suited for this purpose. The base loaded whip antenna normally provides effective communications. For greater range and more reliable operation, a full quarter wave whip may be used. Either of these antennas uses the metal vehicle body as a ground plane.Once the antenna is mounted on the vehicle, route the coaxial cable so that it is not next to any power cables or vehicle cables. Connect the PL-259 to the antenna connector on the rear panel of the Huracan HR-07-NZ. Make sure that the cable does not interfere with the safe operation of the vehicle.
6. VSWR:(Requires external s.w.r meter)
Before use, it is important to determine the antenna system’s VSWR (voltage standing wave ratio). You will need a high quality SWR bridge (meter) to accurately tune your antenna system. First, make sure the SWR bridge is in good working order and is calibrated. To ensure your radio is performing properly the VSWR should never exceed 1.5 to
1. Never transmit on any antenna system where the VSWR exceeds 1.8 to 1.This will stress the output stage and could destroy the RF mosfets; this type of misuse and failure is not covered under warranty. Measure the VSWR at the center of the operating band. Tune the antenna (according to the antenna manufacturer’s tuning instructions) so that the VSWR is as close to 1 to 1 at the center of the operating band. Next, measure the VSWR at the lowest and highest frequency of the transceiver. If the antenna has a wide enough frequency range and band-pass, he VSWR
treadings should be below 1.5 to 1 across the entire operating band. If at the lower or upper end of the transceiver operating frequency, the VSWR measures more than 1.5 to 1, it is recommended that the antenna be retuned before operating on those frequencies.If you are experiencing unusual VSWR readings check for the following possible problems:) 1: Make sure that the antenna is installed properly and grounded.
2) Check all coaxial cable and connectors for defects and poor routing.
3) If testing a vehicle installation, make sure that all vehicle doors are closed when testing.
4) Do not test near or around large metal objects or buildings.
TUNING THE ANTENNA FOR OPTIMUM SWR
Since there is a such a wide vanity of base and mobile antennas, this section will strictly concern itself to the various types of mobile adjustable antennas. Because the antenna length is directly related to the channel frequency, it must be tuned to resonate optimally all Frequencies of the transceiver.
28.000mhz requires a longer antenna than
29.700mhz, because it is lower in frequency. Due to the various methods of adjusting antennas for proper SWR we have chosen what we think is the optimum method:
WARNING CONTINUOUS OPERATION OF THIS TRANSMITTER WITH GREATER THAN 4:1 VSWR ANTENNA MISMATCH MAY RESULT IN RF AMPLIFIER DAMAGE.
A. Antenna with adjustment screws (set screws)
1. Start with the antenna extended and tighten the set screw tightly enough so that the antenna can be lightly tapped with your finger for easy adjustment.
2. Set your transceiver to a mid band frequency. Press PTT (push-to-talk) switch, and tap the antenna shorter. The SWR meter will show a lower reading each time the antenna is tapped. By continuing to shorten the antenna you will notice the SWR reading will reach a lowest point and than start to rising again, this means the optimum tuning being pressed for center operating frequency of your transceiver.
