 # Richonguzman / CD2RXU LoRa APRS iGate/Digirepeater
-# Firmware for Tx and Rx !!!
+
+This next generation LoRa iGate can work as:
+- pure RX-iGate, 
+- 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
+- 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
+...

+b) Choose stationmode
+
+    1 = RX iGate, black "L" as symbol
+
+    2 = 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.

+
+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) section other
+    
+    adjust beaconInterval to a suitable value. A normal value is 45 mintes, it is recommended not to go below 30min.
