    Hi

    I have a weird fenomenon going on lately,.

    On random times in a 2way qso the TX output will drop, and the repeater itself is not accesible anymore.. whilst the person is still talking at the input.
    If the person stops his transmission the repeater resets itself again.

    I can happen after the first 2 seconds of the start of the transmission, but it is really random.

    I have checked the log, and It tells me that the TX is shutdown because it is on too long.
    But this is not the case, because it can happen right after a few seconds of a new transmission.

    I have already set the time out timer to waaay long.. but this doesnt have any effect.

    Any ideas?

    This could be a problem if you are using VOX for RX. Is that the case?

    If you could share some of your log that might be helpful. It is located here: /var/log/svxlink

    You can also watch it realtime using this KB article:
    Watching the SVXLink Log (Real Time)

    I seem to recall that you are on a Raspberry Pi 2, correct? And using ORP 1.1.0?

    Just thought of this. The COS pins default operation is active low, in other words when the COS GPIO pin is grounded then that sets the COS to active, when it is high (3.3v or so) then it is inactive. Make sure that you have a pull up resister on your input pin so that when the pin is not grounded it get pull up to the voltage from a 3.3v pin. This will prevent the pin from floating in value. This is my guess as to what might be happening. When the pin is released, once in a while it floats closer to ground (0v) and keeps the input active until the transmitter times out. TX time out is a built in function to protect the the Transmitter. Hope that helps.
