Extruded aluminum housing with stamped and printed front. At the back all the necessary connections and power. Ent? Processor board, with internal 1200 baud modem software. The modem is also switchable to a 300 baud rate.
All connections required for operation to the Internet and external Transceivers. The connection to the Internet or to Hamnet via RJ-45 interface. The connection to the TRX is a mini 6-pin DIN socket. The I-Gate can be powered via the DC jack with 12 volts be. The power consumption is very low with only 1.2 watts.
The APRS mode is appropriate, external recipients or Transceivers in the 2m band – 144.800 MHz or in the 10m band on 29.250 Mhz 1200 baud.
After switching the software modem to 300 baud APRS can communicate with external Shortwave equipment preferably in the 30m band on 10.147 Mhz USB or 20m Band are carried out on 14.103 Mhz LSB.
When using the built-KISS interface with 9-pin. Sub-D connector for TNC or OT2 / 3 to an external device 2m, the software modem can simultaneously be used for shortwave. It may also be a hand-held radio device, such as 7 THD be connected with integrated KISS interface.
A waterfall chart via browser allows frequency adjustment of the APRS Data streams on shortwave.
Remote control and configuration are possible via PC with an Internet browser.
Remote control and configuration are also possible with a smartphone.
WX data transfer of meteorological stations. There are different brands predefined. The weather station has an RJ-12 modular plug on the I-Gate are connected to visualize the weather data on the Internet. The Feeding the data to the APRS WX server automatically.
Option 1: A slot for a two-channel DSP modem is present. The Retrofitting of 300/1200 baud DSP board is possible without adjustment work. The Modem provides for 2 shortwave devices AFSK transmit signals ready operates the PTT AFSK and demodulates received signals at 300 baud. The connection is made about 2 pieces mini-DIN 6-pin connectors to the outside.
The DSP modem can also 2m on 144.800 Mhz with two 1200 baud for two 2m TRX eg use of directional antennas for better power supply used by valleys. Although APRS signals simultaneously
different directions are received at the site, or if the particularly large catchment area will be received, with directional antennas and separate demodulation achieve considerable reduction of the collision signals.
Option 2: Iinternal VHF TRX is installed on the slot provided for APRS in the 2m band.
Option 3: OLED display is used in the front panel for direct Waterfall display on the device. Also weather data, statistics and equipment settings can be displayed above.
Option 4: Power over Ethernet Power over LAN10/100 Connection. (PoE)
A block diagram and the waterfall diagram are available in PDF file on the last page included.
APRS packets on all the current paradigms Nn with automatic Path reduction applied.
Depending on the configuration level by the firmware via the Internet up to 4 external Transceiver and a weather station with the APRS server, according to the selected configuration, exchange data.
