# Richonguzman / CD2RXU LoRa APRS iGate/Digirepeater
|
|
|
|
This next generation LoRa iGate can work as:
|
|
- pure RX-iGate,
|
|
- Rx+Tx-iGate and distribute messages and weather forecasts to heard trackers, and
|
|
- Digipeater in simplex or split-frequency environment.
|
|
|
|
In all configurations the display shows the current stationMode, heard packets and events the iGate is currently performing.
|
|
|
|
But under the hood is much more:
|
|
|
|
- Sending events to remote syslog server.
|
|
- OTA update capability (for Firmware and Filesystem).
|
|
- RX first, TX will only be done if there is no traffic on the frequency.
|
|
- automatic update of the Lora symbol at APRS-IS, black "L" for pure RX, red "L" for TX capability and green "L" for digipeater.
|
|
- support for multiple WLAN with corresponding coordinates.
|
|
|
|
and more will come:
|
|
- Web-UI
|
|
- support for BME280 sensors, sending to APRS-IS
|
|
- ...

Instructions (add your information into the '/data/igate_conf.json'):
|
|
|
|
a) Change _callsign_ from "NOCALL-10" to your CALLSIGN + SSID.
|
|
|
|
b) Choose _stationMode_:
|
|
|
|
1 = RX iGate, black "L" as symbol
|
|
|
|
2 = Rx + TX iGate, red "L" as symbol, HAM only. RX will be sent to APRS-IS, Messages will be sent via Lora. Same frequency for RX and TX. By using this feature you have comply with the regulations of your country.
|
|
|
|
3 = Digipeater simplex, green "L" as symbol, HAM only. Received packets containing WIDEx-x in path will be digipeated on the same frequency. By using this feature you have comply with the regulations of your country.
|
|
|
|
4 = Digipeater split frequency, green "L" as symbol, HAM only. Received packets will be digipeated on a different frequency. Frequency separation must be 125kHz or more. By using this feature you have comply with the regulations of your country.
|
|
|
|
IgateComment and DigirepeaterComment will be sent to APRS-IS or via RF, depending on your stationmode
|
|
|
|
c) WiFi section:
|
|
|
|
adjust SSID and Password to you WiFi, add the GPS to "Latitude" and "Longitude" (info from GoogleMaps) of your new LoRa iGate. (If stationMode 3 or 4 selected, add also GPS info to Digirepeater Section).
|
|
|
|
d) APRS_IS section:
|
|
|
|
change "passcode" from "VWXYZ" to yours (remember that is 5 digits integer) and choose a server close to your location (see https://www.aprs2.net/)
|
|
|
|
e) LORA section:
|
|
|
|
adjust TX frequency and RX frequency matching your stationmode and country. Remember,
|
|
|
|
at stationmode 1, 2, and 3, RX and TX frequency shall be set to 433775000 (443.775MHz, deviations possible, depending on your country)
|
|
|
|
at stationmode 4, RX frequency shall be set to 433775000, TX frequency shall be set to 433900000 (deviations possible, depending on your country). There must be a frequency separation of 125kHz or more.
|
|
|
|
adjust power to your need, valid values are from 1 to 20
|
|
|
|
f) Syslog section:
|
|
|
|
adjust server, port to a suitable value.
