4 attempts. First one stuck, next three worked. Attempts 1 and 3 were done the same way.
Iteration two is odd, when you start up with the TX off, the mod should wait with a single blink until you turn the TX on. Yours goes straight ahead waiting for the boot of the drone to finish. The mod should wait with 2 blinks if you turn on the TX and the flightmode is not LAND.
Observe what happens in Hyperterminal when you turn off the TX, at least one of the channels should turn red to signal RX failure.
