(1) ADSBEXCHANGE FEEDER:
You are using an older version of adsbexchange, which used mlat-client as it-is.
The latest version of adsbexchange installs mlat-client to virtual environment
and uses MLAT_VERSION=“ae5fd32bb443ddbb7dd0194b8675988f9fb8800e”.
I understand that this is done in order to avoid using mlat-client supplied from Radarbox24 repositories. As far as I know this is because RB24 mlat client package has something modified from mutability’s mlat-client to customize it for their feeder. As @wiedehopf was involved in making adsbexchange’s mlat-client to use virtual environment and bump mlat version, he can better explain this.
See output of following command, there is no mlat-client there:
pi@orangepipc:~$ top -u adsbexchange

(2) B24FEEDER
The rbfeeder installs mlat-client package from rb24 repositories (see 2nd last line below)
However the rbfeeder does not use mlat-client directly, but through python 3.7, and that may probably be the reason it is not shown in output of top command. Below is the file /etc/rbfeeder.ini. Please see the line under [mlat] which starts with mlat_cmd=.
pi@orangepipc:~$ cat /etc/rbfeeder.ini
[client]

log_file=/var/log/rbfeeder.log

mlat_cmd=/usr/bin/python3.7 /usr/bin/mlat-client --results beast,listen,30007
[dump978]
#dump978_enabled=true
NOTE:
Contrary to common belief, the Radarbox24 does feedback mlat results. To display it on SkyView Map, you have to add following at the end of the line starting with mlat_cmd= to direct their mlat-feedback to port 30104:
--results beast,listen,30104
However as I do not want RB24 mlat feed-back to mix with FA mlat feedback on Skyview map, I used port 30007 instead of 30104, and configured ModeSMixer2 to display it on its map. Here is the complete line in my rbfeeder.ini file:
mlat_cmd=/usr/bin/python3.7 /usr/bin/mlat-client --results beast,listen,30007
