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. 73s, thanks, N0AGI YouTube Video FTM-400 DR – Bluetooth Module (BU-2) and Installation Pictures 8 Responses to Yaesu FTM-400DR Bluetooth Module BU-2 Brad W6BJB on February 21, 2016 at 10:48 am 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. Reply N0AGI on February 21, 2016 at 4:06 pm 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 Reply Hendrik Susanto on August 12, 2016 at 1:35 am 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! Hendrik W1FJC Reply N0AGI on August 17, 2016 at 6:56 am hi Hendrik – good question. I have not tried this. But, can try that later this week and post back a reply. Reply Jerry - N2JPZ on November 1, 2017 at 8:32 pm 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! Reply N0AGI on December 13, 2017 at 8:07 pm hi Jerry – unfortunately, that took a back-burner priority. Reply JOSE (EA4GZP) - SPAIN on April 7, 2018 at 12:18 pm Hi there, I´m about to order the UB-2 Bluethooth module for a Yaesu FTM-100DR….due I want the sound of it on an external bluetooth speaker that I can hear/move around my house (out of the shack room). Do you think that it will pear it? Thanks for your help!!! Reply N0AGI on April 26, 2018 at 7:55 pm 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 Hope that helps – best wishes Reply Leave a Reply to N0AGI Cancel reply Your email address will not be published.Comment Name Email Website This site uses Akismet to reduce spam.
