JVC TH-D75A Handheld Transceiver Tribander Instruction Manual

TH-D75A Handheld Transceiver Tribander

Product Information: GPS

The product features a built-in GPS function that allows users
to access GPS satellite information and display position
information such as latitude, longitude, time, altitude, heading,
and speed. The built-in GPS receiver function can be used together
with the transceiver function or independently. The product also
offers two display modes: North Up display (displays North as the
top) and Heading Up display (displays the current travel direction
as the top).

Built-in GPS Setup

1. Access Menu No. 403.

2. Select either [Normal] or [GPS Receiver] mode.

3. If [Normal] mode is selected, the display will continue to show
   the frequency and the product can be used as a normal
   transceiver.

4. If [GPS Receiver] mode is selected, the display will only show
   GPS information. The transceiver’s transmit and receive
   capabilities will be turned off, and only GPS operation will be
   available.

5. Press [A/B] to restart the transceiver with the selected
   mode.

(approximately 5 minutes), the GPS power source will turn off after
the programmed timer expires. This helps prevent unnecessary
battery consumption. When there are many reception satellites and
the GPS is stabilized, the GPS power source will repeatedly turn on
and off.

APRS®

APRS DATA COMMUNICATION · This function uses the APRS format for data
communications including your station position, messages, etc. · When data is received from another station directly, via digipeaters and/or IGate stations, the direction of the received station (from your station’s perspective), their distance, and their grid square locator is displayed. Any comments sent by the other stations are also displayed. · APRS (Automatic Packet Reporting System) is a worldwide system introduced by Bob Bruninga, WB4APR. < APRS® is a software program and registered trademark of Bob Bruninga, WB4APR.> Official APRS Website: http://www.aprs.org
APRS Network
Digipeater · Digipeater (Digital Repeater) relays digital packet data.
When a Digipeater receives a packet, it saves it to memory. When the reception ends, the packet data is re-transmitted on the same frequency. Using Digipeaters, it is possible to exchange APRS packets long distances.
IGate · IGate (Internet Gateway) is a very useful and important
feature for APRS as well as Digipeater. IGate stations bridge APRS packets between RF and the Internet. By going through the IGate stations, you can enjoy the communication with the further distant stations which are not covered only by Digipeaters. Digipeater stations and IGate stations are operated by the volunteer people in each region.
BASIC SETTINGS
This part covers only the minimum necessary settings for basic operation as an APRS handheld portable station. Refer to the User Manual (detailed instruction manual) on the Website for more advanced settings.
My Callsign
Program your Callsign using a maximum of 9 alphanumeric characters including SSID (Secondary Station IDentifiers) such as -7, -9, or -14. Unless you program a Callsign, you cannot transmit APRS packets. 1 Access Menu No. 500.
The display for entering a Callsign appears. You can enter 0 to 9, A to Z, and ­.
2 Press [ENT] to set the Callsign.
Note: ¡ For SSID characters, refer to the guideline on the Website (http://
aprs.org/aprs11/SSIDs.txt) by Bob Bruninga, WB4APR. ¡ When all settings are blank, “NOCALL” is automatically set. In this
case, the Position packet (Beacon), Object Packet, or Message packet cannot be transmitted.

Selecting your Station Icon
1 Access Menu No. 501.

2 Select an icon which will be displayed on the monitors of other stations as your ID. You may select an icon depending on your current location. It is important that the icon conveys the operational status of the station as well as the SSID.

Note: ¡ Set an icon that represents your operational status. (For example,
setting an Aircraft icon or Balloon icon to a fixed station will cause confusion when a station receives a beacon.)
Setting the Data Band Frequency
Set the data band frequency to the APRS network frequency. The default setting of the data band is band A. You can change the data band to band B by Menu No. 506.
Note: ¡ The APRS network frequency will depend on what region of the
world you are operating as follows: North America: 144.390 MHz, Europe: 144.800 MHz Australia: 145.175 MHz, New Zealand: 144.575 MHz Argentina: 144.930 MHz, Brazil: 145.570 MHz Japan: 144.640 MHz (9600 bps)/ 144.660 MHz (1200 bps)

D-STAR

D-STAR INTRODUCTION · In the original D-STAR (Digital Smart Technologies for
Amateur Radio) plan, JARL envisioned a system of repeaters grouped together into Zones.
· The D-STAR repeater enables you to call a D-STAR station in another area through the Internet.
· The transceiver can be operated in the digital voice mode, including low- speed data operation, for both transmit and receive.
Note: ¡ Before starting D-STAR, the following steps are needed.
STEP 1: Enter your Callsign in the transceiver. STEP 2: Register your Callsign to a gateway repeater.
DV MODE/ DR (D-STAR REPEATER) MODE
DV (Digital Voice) mode is a mode you can use for direct call without using a repeater.
DR (D-STAR Repeater) mode is a mode you can use for D-STAR repeater operation. In this mode, you can select the preprogrammed repeater or frequency in “FROM” (access repeater), and UR Callsign in “TO” (destination), as shown below.

REGISTER YOUR CALLSIGN AT A GATEWAY REPEATER
To use the Internet, you must register your Callsign with a repeater that has a gateway, usually one near your home location.
Registration Process
This section describes the Callsign registration process at a repeater that is connected to the US Trust server. There are other systems as well, and they have their own registration process. For information on how to register on one of them, contact the administrator of a repeater that uses the alternate system. 1 Access the following URL to register your callsign.
https://regist.dstargateway.org

TO: Destination (CQ/Other area repeater/Specific station)
FROM: Access repeater

DR mode (Main band)

Communication in DR mode
In the DR mode, the transceiver has 3 communication ways. Local area call · To call through your local area (access) repeater. Gateway call · To call through your local area (access) repeater, repeater
gateway and the Internet to your destination repeater or individual station’s last used repeater, using Callsign routing. Call by Callsign designation · To call by designating the Callsign of the specific station. This call is relayed automatically to the last accessed repeater.
Basic operations in DR mode · Press [ ] (1s) to set “TO” (destination).
You can set “TO” in Local area call, Gateway call, and Call by Callsign designation, etc. · Press [ENT] (1s) to set “TO” (destination) by Call History. You can recall in Gateway call, etc. · Press [ ] (1s) to set “FROM” (access repeater). You can select “FROM” (access repeater) in Local area call and Gateway call. · Press [ ] (1s) to display the reception history list.
Note: ¡ The basic operations in DR mode are not supported in DV mode. ¡ The transceiver has a Time-Out Timer function for digital
repeater operation. The timer limits a continuous transmission to approximately 10 minutes.

36

2 The “D-STAR Gateway System (REGIST)” screen appears. Click [Register] to start the New User registration.
3 Follow the registration instructions on the registration screen.
4 When you receive a notification from the administrator, your Callsign registration has been approved, but the whole process is not yet complete.
Note: ¡ It may take a few hours for the administrator to approve you. 5 After your registration is approved, log in your personal
account with your registered Callsign and password. After you have logged in, click [Personal Information]. The following screen appears.
6 Follow the “Registration Instructions” on the website to register your D-STAR equipment information.
7 When your registration is complete, log out of your personal account, and start using the D-STAR network.
Note: ¡ You must register your D-STAR equipment before you can make
calls through the gateway.

MY CALLSIGN
Set your Callsign to the transceiver in DV/DR mode. Transmission in DV/DR mode will not be possible if you do not set your Callsign.
Up to 6 Callsigns can be registered. For your Callsign, you can register a Callsign that is within 8 characters and any memo (name or rig name, mobile operation destination, etc.) that is within 4 characters after a slash (/).
1 Access Menu No. 610.
2 Select a number for registration and press [A/B].
3 Input your Callsign.
· For the character input procedure, refer to page 15.

The following table shows the items in the Digital Function Menu in DV mode and DR mode.
