Then this transceiver causes the VC-H1 to capture an image, executes the superimposition, and transmits the image to the target station.
AUTOMATIC PACKET/ POSITION REPORTING SYSTEM The Automatic Packet/ Position Reporting System (APRS) is a software program and registered trademark of Bob Bruninga, WB4APR. He has made packet communications much more exciting than before. This program allows you to track mobile stations on a map which you recall on a computer screen. Imagine seeing one mobile station moving on the map which can be scaled from .5 to 2000 miles. You also may be tracked on the computer screen of another station.

You will not receive APRS data from stations beyond this distance. 1 1 Press [MENU] to enter Menu mode.
APRS MESSAGE 1 2 3 4 5 6 7 8 The APRS supports a function for transmitting and receiving a message independent of position reports. You can transmit a message to a single station only or a bulletin to all other stations in your group. If you specify a station, the entered message is transmitted up to 5 times until a reception acknowledgment is returned. Each message which you transmit can consist of up to 45 alphanumeric characters.
RECEIVING A MESSAGE Each time a proper message is received, the frequency display is interrupted to show information as below: When a duplicate message from the same station is received, an error beep sounds. In addition, “dM” and a call sign appear on the display. 2 STA CON STA CON 5 96BCONDUP 5 7 96BCONDUP 3 9 9 7 1 4 Indicator 5 6 • The display shows only the first 24 characters of the message.

To transmit a bulletin to all other stations in your group, enter “BLN ” as the call sign; where must be any single alphanumeric character. When the length of your bulletin exceeds 45 digits, you may transmit more than one packet to send the entire bulletin. You can use to indicate the sequence of the bulletin portions.
When entry of a message (or bulletin) is completed, this transceiver automatically transmits it 5 times (max.) at intervals of 1 minute. The table given on page 78 also shows indicators that appear for outgoing messages (or bulletins). “+” is assigned to messages (or bulletins) that have not yet been transmitted 5 times. You can also manually transmit all of those regardless of the 5-minute timer. For a message: 1 Press [MSG].
WIRELESS REMOTE CONTROL (TH-D7A ONLY) If you also have a KENWOOD multi-band mobile transceiver, you can control one of its bands by sending DTMF tones from this handy transceiver. You will find this function useful when you want to control your mobile transceiver from a location outside your vehicle. Note: ◆ You can remotely control only the mobile transceivers that have both the DTSS and Remote Control functions. ◆ The FCC rules permit you to send control codes only on the 440 MHz band.
1 6 Turn the transceiver power OFF. CONTROL OPERATION 7 Press [PTT]+[MR]+ POWER ON. When in Remote Control mode, the keys of the handy transceiver will function as below. Each time you press the desired key, the handy transceiver will automatically enter transmit mode and send the corresponding command to the mobile transceiver. • The transceiver enters Remote Control mode. “MOBILE CTRL” appears. 2 3 STA CON 4 5 7 96BCONDUP 9 5 6 7 • To exit Remote control mode, repeat steps 6 and 7.
SKY COMMAND 2 (TH-D7A ONLY) The Sky Command 2 allows remote control of a TS-570D, TS-570S, or TS-870S HF transceiver. This system requires two TH-D7As and the optional cables which connect one TH-D7A to the HF transceiver. You will use one TH-D7A as both a remote control and speaker microphone. This TH-D7A is called “Commander”. The TH-D7 connected with the HF transceiver is called “Transporter”. It will function as an interface between the Commander and the HF transceiver.
1 2 3 4 5 6 7 8 9 10 11 CONNECTING THE TRANSPORTER WITH THE HF TRANSCEIVER You can use the optional cables (PG-4R) to connect the Transporter with the HF transceiver. For these cables, contact your authorized KENWOOD dealer. Note: ◆ Switch OFF both the Transporter and HF transceiver before making the connection. ◆ The Transporter automatically transmits its call sign in Morse at regular intervals because of the legal requirement; therefore, transmit sidetone must be output from the HF transceiver.
PREPARATION FLOW The following steps should guide you to a good start of Sky Command operation. First connect the Transporter to the HF transceiver {page 84}. y On the Commander Access Menu 4–3 and select and Transporter the tone frequency {page 86}. • Select the same tone frequency on both transceivers. • For the selectable frequencies, see the table given on page 22. q On the Commander Select the same VHF and UHF and Transporter frequencies.
