Problem, TX drops now an then

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:

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.
