In the event you need to make changes to the 360 radar mlat client for example you need to change your location then just follow these simple instructions below.
Firstly we need to login to the raspberry pi via terminal or putty and issue the command.
sudo nano /etc/default/lfw-mlat-client-rxX
where X is the receiver number (1, 2, 3 or 4).
Make any changes you require and then save with Ctrl X, Y and Enter
Then restart MLAT with:
sudo service lfw-mlat-client-rxX restart
again where X is 1,2,3 or 4
