Thread: FT-991A and RT Systems Programming Software

  1. #1

    Default FT-991A and RT Systems Programming Software

    I got my license about a month ago and have recently purchased a Yaesu Ft-991A transceiver. I also bought a
    copy of RT Systems software for programming the radio. I didn't want to have to hand enter all the info for the many repeaters in the area. After installing the software I plugged in the USB cable from the radio. To my surprise the audio on my laptop went silent. I know that because I was watching a youtube video about using this particular software and then the sound cutout.

    Has anyone else had this problem or have any clues about what might be wrong?

    I also use RT with a 991a, have not experienced any problems. Probably a driver conflict. A quick peak at device manager should provide some clues, or maybe reassign the USB to a different COM port number.

    The cable interfaces the computer with the audio output of the transceiver. Just be glad that it didn't key the transceiver and start transmitting the garbage you were looking at..
