I am also experimenting this issue, where the first second is cut off, I was able to adjust the timers down to the 1 second mark, But still miss a second or so. We are using Pi 3, ICS 1x in simplex mode as a echolink node. Ive edited the SVXlink.php with the SQL_START_DELAY to 2350, because we were having a loop, as soon as the repeater would unkey, it would detect the squelch and rekey back up. But with the SQL_START_DELAY i was able to stop that. Also and only when someone is logged into echolink via the app when someone keys up and then unkeys the repeater will key back up. Once the person logs off echolink it doesnt do it. Ive had this issue on 2.1.2 and talked with Aaron and wanted me to drop down to 2.1.1 which im on now.
