1. You should download sdr_commander:

http://www.afedri-sdr.com/index.php/downloads/category/15-sdr-commander-command-shell-utility

2. You should create a script in the OpenWebRX directory to run sdr_commander to initialize the receiver.

start_afedri.sh contents:

#!/bin/bash
SAMPLE_RATE=192000
GAIN=17
FREQUENCY=7100000
./sdr_commander  -t192.168.0.8 -sn$SAMPLE_RATE -g$GAIN -q0
./sdr_commander  -t192.168.0.8 -f$FREQUENCY
sleep 1
python openwebrx.py

In config_webrx.py, you should change these settings:

samp_rate = 192000
center_freq = 7080000
start_rtl_command="sdr_split -i192.168.0.8 -u50000 -O -s{samp_rate} -f{center_freq}".format(rf_gain=rf_gain, center_freq=center_freq, samp_rate=samp_rate) 
format_conversion="csdr convert_s16_f"

3. Run start_afedri.sh that will also start OpenWebRX:

chmod +x start_afedri.sh
./start_afedri.sh
