    Yes, the same arguments are working since one year

    --net --net-http-port 8082 --aggressive --enable-agc

    as far as I know from this and other threads "--agressive" is not recomendet as you get a lot of "false positives" since the are hex-codes that diver only by one bit

    Would be nice to compare the coverage with if you remove "--aggressive --enable-agc".

    Thanks for your tip Astro.
    @vinny: I removed both entries now, but I'll wait till next service restart (i have a daily restart Job running) so we can compare today with tomorrow (tomorrow I have a bit less traffic compared to today, 5-7%).

    Hi vinnyspb ,

    I just remove the --aggressive arguments which I've been use for long time , interesting thing is I seems lose few nm but the mode-s packets rate goes up ,

    mean more position report , ain't I correct ?

    Hi

    Easy apply patches does not work mutability repo have significant changes since nothing happens in MalcolmRobb repo i have tried.
    Mutability's fork brings for me better results (more message from gnd, more messages per sec and a better range) and a important thing the CPU usage is lower, a little decision aid from me.

    I've turned off my FR MLAT transmission for now while I test mutability to see if it is indeed better, and if it is, then I likely won't turn FR MLAT back on unless they convert to using an unmodified version of mutability.. cpu usage alone is significantly lower, this is a huge incentive all on it's own.. While I acknowledge that some things would need to be re-coded, it's still disappointing that we do not get back MLAT data for plotting via VRS etc, would love to see that change..

    Thanks

    Yesterday's stastics without "--aggressive --enable-agc"

    Aircraft seen: 1,158
    Positions reported: 23,522
    Maximum distance: 80nm
    and this is from Monday

    Aircraft seen: 1,345
    Positions reported: 46,355
    Maximum distance: 106nm
    I will test Malcom Robb's fork tomorrow to see if its running better.
