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.
