APRS DAtA CommuniCAtion (APRS BeACon)
u
This function uses the APRS format for data communications including your station position, messages, etc., when connected to a
GPS receiver.
u Even with the GPS receiver not connected, similar communications can be performed by entering the position data.
u
When data is received from another station, 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 station are also displayed.
u
Meteorological data obtained from a connected Weather Station can be transmitted.
u APRS (Automatic Packet Reporting System) is a worldwide system introduced by Bob Bruninga, WB4APR .

CAll Sign AnD BeACon tyPe SettingS
u
When an APRS/NAVITRA beacon is created, set the call sign and beacon type (APRS/NAVITRA) (Menu No. 600).
u
SSID (Station System Identification) can be added to the end of your call sign (for example, W6DJY will become W6DJY– 11).
SSIDs can range from “– 1” to “– 15”, so that each call sign can have up to 16 settings. There are no strict rules governing the usage
of SSID, but for APRS SSID, the following guideline is generally followed:
None Home Station, Home Station running IGate. -9 For mobiles
-1,-2,-3 For digipeaters and other home stations -10 For operation via the internet only
-4 HF to VHF Gateway -11 For APRS touch-tone users (and occasionally Balloons)
-5 IGate (non- Home station) -12 For portable units such as Laptops, Camp Sites, etc.
-6 For operations via Satellite -13 Unused
-7 Kenwood TH-D7 Handy transceiver -14 For truckers
-8 For boats, sailboats and ships -15 For HF
gPS ReCeiVeR SettingS
u When the GPS receiver is not connected to the RC-D710 (fixed station), set the GPS receiver Menu No. 602 (GPS PORT – INPUT)
to [OFF] (default value). If you do not connect the GPS receiver when you set up [GPS], your station position location will not be
correct, and the distance and direction of other stations will not be displayed. Therefore, you should set your position data using
Menu No. 605 (MY POSITION).

DigiPeAt
u
The term digipeat means that the beacon packet data is relayed. When
a digipeater (relay station) receives a packet (beacon), it saves it to
memory. When the reception ends, the data is re-transmitted. Using
digipeat, it is possible to send beacons long distances.
u
In order to perform a digipeat, you must set up a packet path (relay path)
(Menu No. 612). For relay modes, you can specify a direct call sign or
you can use “RELAY,WIDE” or “WIDE2-2”, specifying a common alias
and hops number. Set the transceiver’s packet path according to the
digipeater settings.
u Digipeat is very useful in reaching other stations when you have a weak
signal. However, you need to set up the total hops numbers and beacon
transmissions moderately to prevent channel congestion. WIDE-type:
This degipeater can send the packet over a wide area.
RELAY-type:
Regional degipeaters are also called “Fill-in type” relays.
These degipeaters are used for mobile stations when a
signal cannot reach a WIDE-type degipeater.
