Experiment Setup with .toml and .sh files and description of my shack.

My PhantomSDR folder is in root - PhantomSDR-Plus/
I've created two files in the root:
go.sh for starting the server and kill.server for stoping it.
Modificated config-rx888mk2.toml is located in PhantomSDR-Plus/


The "go.sh" file is this. You can call it typing $ ./go.sh in terminal:

####----####
#!/bin/bash
cd ~/PhantomSDR-Plus
killall -s 9 spectrumserver
sudo killall -s 9 rx888_stream
sleep 1

# Turn USB powersaving off
echo on | sudo tee /sys/bus/usb/devices/*/power/control > /dev/null
if test -e ~/PhantomSDR-Plus/rtl.fifo; then
echo fifo alredy exists
else
echo creating fifo...
mkfifo ~/PhantomSDR-Plus/rtl.fifo
fi
sleep 1

RUST_BACKTRACE=1

sudo ~/PhantomSDR-Plus/rx888_stream/target/release/rx888_stream -f ~/PhantomSDR-Plus/rx888_stream/SDDC_FX3.img -s 60000000 -g 127 -a 63 -m high --pga -r -d -o - > ~/PhantomSDR-Plus/rtl.fifo &
sleep 1
~/PhantomSDR-Plus/build/spectrumserver --config ~/PhantomSDR-Plus/config-rx888mk2.toml < ~/PhantomSDR-Plus/rtl.fifo &
# > /dev/null 2>&1 &

exit
####----####



The "kill.server" is this. You can call it typing $ ./kill.server in terminal:

####----####
#!/bin/bash

killall -s 9 spectrumserver
killall -s 9 rx_sdr
sudo killall -s 9 rx888_stream
killall -s 9 rtl_sdr

# service sdrplay stop

sleep 2

exit
####----####


The "config-rx888mk2.toml" is this (located in /PhantomSDR-Plus)

The antenna is EFHW 38+7 meters long, with 64:1 balun and a loading coil 192uH for 160m band (at 38 meters). The Antenna is only 6 meters above the ground (due to limitations of greek gov.). A 60MHz low pass filter is also used.
With this setup there is not any cross modulation or overloads for now, during day and night.
The receiving system is located in Athens of 4M habitants and the noise of the city may appears, but it is not critical.
The antenna system is shared using a splitter/combiner with my Perseus, which is also on air using PerseusSDR server's sharing.
