Yaesu FTM-400DR Bluetooth Module BU-2

Earlier over the weekend, I installed a YAESU BU-2 Bluetooth Module into my FTM-400 DR. This page is just a log of that quick exercise. Accompanied by a YT video.

    Do you happen to hear an intermittent buzz on 70cm frequencies after you installed the BU-2? I’ve tried two different boards in the same 400 and I get an intermittent buzz until I connect the headset and then it goes away.

      hi Brad – i have not experienced that specific issue. I do scan a few UHF and VHF frequencies while on the road and i’m yet to see this issue. Does your FTM-400 have the latest DSP and FW ? Thanks for visiting and asking. 73s

    Hello N0AGI
    Do you know if the BU-2 will pair with an Android tablet? I’m thinking if it does, then maybe APRSDroid might work with this radio through Bluetooth. Thanks!

    Greetings! Were you ever successful in pairing the BU-2 to an Android and running APRSDroid? My TM-D700 is getting long in the tooth and I’ve been thinking the Yaesu with the big color screen would be nice.

    Thanks!

      hi Jerry – unfortunately, that took a back-burner priority.

      hi Jose – the BT module is very picky about which end-point device (i.e., speaker/mic) that it wants to pair with. So, in short, I am not sure. I suggest you do some research on compatibility of which speaker/mic you’re pairing with. Hope that helps – best wishes

    What kind of Bt range do you get from it? I will be mounting the radio body in my trunk and wanted to make sure it would reach. My VX8R only gets about 5’ of dependable range so I wanted to make sure that the FTM400 range is better than that.

      hi Rob, to be honest, I never ended up trying the BT capability as I never ended up purchasing the BT headset. But, knowing BT technology stack, I suspect you should not have any issues if your travel range is btwn your trunk and the driver cabin.
