3 commonly used radio jumpers
Three commonly used radio jumpers are connected to the radio’s hand microphone and 51WG5.
The following is a detailed description.
51WG5 uses 3 signal wires of MIC PTT GND of the hand microphone port to realize the function of
controlling the radio station to transmit APRS signals.
According to this principle, you can make different jumpers yourself to adapt to your own radio
station.
Note: The hand microphone jumper is only connected to the radio's hand microphone port, and
must not be connected to other ports of the radio.

PC programing
The following setting software interface is for reference only, the version is constantly updated, there
may be differences
Hardware connection:
1. Connect the APRS 51WG5 series with the mobile phone USB data cable (provided by yourself)
2. Open the 51 series general setting software and select the correct port number.
3. Read settings or modify settings, and the host automatically saves them.
Note: Basic knowledge, set parameters, pay attention to the input method, input in English, do not use
full-width characters, try not to copy information from other documents, so as not to bring in hidden
characters.
Input full-width characters, garbled characters will be displayed when the data is read out, and the
51WG5 motherboard may not work properly.
Writing hidden characters may also make the 51WG5 board work abnormally
When the setting data is garbled, delete the garbled data and rewrite it.

Use the set longitude and latitude of the fixed site to calculate the relative distance, true north, and
relative direction to the other party.
WS: Do not set
GPS switch ON/OFF
If used in a fixed location, you can select OFF to save battery power.
Track beacon mode:
Divided into 4 types, smart mode, manual mode, queue mode, and timing mode.
You don't need to enable all of them. Generally, you only need to enable one of them, or you can disable all of them.
Track beacon function settings
Note: In the case of the Sport site type, no matter which of the following beacon modes, it will only be transmitted
after the effective positioning of GPS.
Smart mode:
When GPS is positioned, it will automatically launch a beacon according to the heading and speed.
Manual mode:
After GPS positioning, long press F1 (X1C5), and each time you press the PTT button (UV98) of the mobile station
itself, when you release it, it will automatically follow and launch a beacon.
Timing mode:
After GPS positioning, the beacon will be automatically transmitted according to the set time.
Queue mode:
Transmit according to the set time seconds within 1 minute,
Note: The time base is different from general timing transmission. The actual launch time is always the set time + 1
second.
For example, if the queue time is 0 seconds, it will be transmitted according to the following time rule.

GPS power saving
When it is manually pressed or the time is reached, the GPS will be turned on automatically, and the GPS will be
hot-started, and the positioning will be performed within a few seconds, and then the transmitter will be transmitted
and the GPS will be turned off again.
Note: Only manual mode or timing mode is valid.
PATH 1, PATH 2
The relay forwarding and forwarding times with the name WIDE1 or WIDE2 are required.
Default setting: WIDE1-1 WIDE2-0, which means that the relay named WIDE1 is required to be forwarded once, and
WIDE2 is not required to be forwarded.
MIC-E
The beacon data is compressed and transmitted, which effectively shortens the transmission time, reduces the
probability of data being interfered by other signals in the air, and improves the decoding success rate of the receiver.
PTT delay
Before transmitting the signal, the PTT trigger delay, when the other party's SQL response is slow, you can increase the
PTT delay parameter.

Custom information (Note 1)
Up to 60 characters in English and 20 characters in Chinese. The shorter the custom message, the better.
Beacon options
Mileage: The mobile station beacon contains the automatically calculated mileage. Not included in fixed station
beacons.
Satellite: The mobile station beacon contains the number of effective satellites. Not included in fixed station
beacons.
Air pressure: mobile station and fixed station beacons include auxiliary air pressure sensor data.
Voltage: Mobile station and fixed station beacons contain battery voltage sensor data.
Temperature: Mobile station and fixed station beacons include auxiliary temperature sensor data.
Note: Due to the size and structure of the machine, the temperature data is for reference only.
Note 1:
The shorter the custom information, the better, and the fewer beacon options, the better.
The longer the data, the longer the transmission time, and the greater the probability of the signal receiving air
interference, which may reduce the decoding rate of the other party.
Mileage memory
When this option is checked, the real-time mileage will be automatically saved in synchronization and automatically
every time the beacon is launched.
If you don’t check this option, the mileage will be automatically reset to 0 next time you turn on the machine
TX test key
When in a fixed station, press this button, the mobile station will automatically transmit once, with the beacon at
the fixed station position
When in the mobile station, when the GPS has been effectively positioned, press this button, the mobile station will
automatically transmit a real-time position beacon.

2 repeater names can be set
Repeater name 1: Default WIDE1 numbers or English capitals, up to 6 digits
Repeater name 2: Default WIDE2 numbers or English capitals, up to 6 digits
Forwarding condition: When the machine receives a valid beacon,
And the beacon contains the local relay name, and the number of forwarding is greater than 1,
This machine will forward once, and reset the number of forwarding times, reduce it once, and re-pack and send.
If the number of retransmissions in the beacon is 0, no retransmission is performed.
APRS digital relay is a process of receiving, decoding, re-encoding, and sending each time it is forwarded. Therefore,
no matter how many times it is forwarded, the signal quality will always be the best, which is different from traditional
analog voice relay.
APRS digital relay, because the beacon contains the specified number of retransmissions, it will not be
