    Funny... I was playing with my setup today as well. Got a 5/8 2M/440 Larsen antenna mounted up the other day just clamped to the passenger grab bar on my bike and am seeing ~1.4 on an SWR meter. Not bad for a mobile, I think. I just picked up an adapter I needed this afternoon to finally get it all connected together.

    I haven't had much luck finding the extension cable for the SENA headset. Found one made for a security camera that seemed like it would work but they wanted $95 for it. I ended up just moving my SR10 from under the seat to the handlebars. The setup isn't as secure, and I now have a lot of wires on the handlebars, but what are you going to do? When I did so, I did notice that when I tried to exclude the Ground Loop Isolator from the Montana > SR10 connection I was getting feedback with the SR10 wired, so I wired the isolator back in, because I like the fact the SR10 turns on/off with the bike. (I used this Ground Loop Isolator, btw...). I didn't try transmitting because I was in the garage with a T-storm going on, but I'll try tomorrow.

    One thing that's not in the loop yet is I don't have a power connection to the radio (Kenwood TH-D72A HT, btw), so I'm just running that off it's own battery for now. But, I'm hoping the 'filtered' cigarette lighter adapter won't cause the same ground loop issues I was seeing with the Montana.

    I was just going over all my equipment before next weekends ride and found this.


    CHANGES ======= - Enhancements in battery management - Minor Bug fixes in interoperability with phones REVISION HISTORY ================ 1.1 January 2, 2012 - Support Voice Command function of mobile phones - Support multiple point Bluetooth headsets - Temporary disconnection of Bluetooth audio channel

    Also, on 1.1, what is Support multiple point bluetooth headsets?
    does that mean I can interface it with both my SMH-10's :)

    I just upgraded mine to 1.2 last week also, but I didn't pay attention to the updates.

    That could mean it might just remember more than 1 BT headset, but I think it did that already? Maybe it can support 2 headsets now?

    I like the support for the Voice command added in.

    Has this happened to anyone else?

    Normal offroad use but with a regular diet of corrugations (washboards) which I guess has rattled the lock nut off. I can see the lock nut inside the casing. Quite disappointed as I will now be up for my 2nd return to Sena for warranty/quality issues... international postage is not cheap (which I am required to pay both directions).

    I am trying to interface the SR10 using the SR-A0116 cable, for which I have the pinout for the four cores, but no circuit details, i.e. whether I need to use any resistors / isolating caps in the mic and speaker leads, and whether the PTT line needs a resistor - presumably it goes to "ground" when the PTT is pressed ?

    Appreciate any help

    Thanks,

    Nick

    I would expect the SR10 to connect ground (pin 6 black) to PTT (pin 4 brown) when in transmit mode.
    (This gound is more of a common and will probably be isolated from your bike ground. But if the SR10 is powered off the bike, this might really be common ground with the bike.)

    Plug the cable in, turn the SR10 on, and put an ohm meter between the 2 wires, then push the SR10 PTT button and see if you have continuity.

    Now depending on your radio, some Some radios have 3 wires and use PTT to send ground through a resistor to the MIC line on the radio to cause transmit. (I think my Kenwood 2m rig is that way)
    Others have 4 wires, MIC, Audio, Ground and PTT.

    one tip I can give (coming from the Autocom world is "if you have the SR10 on 12v power, and your transmitter on 12V power, you risk a chance of ground loop audio hum while transmitting (or sometimes receiving)
    But I have ridden all day and the SR10 battery was still alive so I never plugged the SR10 into power.
    But the radio don't last more then a couple hours so it needs power.

    Thanks for the quick reply, Towpro :1drink

    It is a FT60 I am using with it on 70 cms at the moment but want to make up leads for one or two others, and understand what the SR10 needs to "see". I make up J-Stick antennas for 70 cms, stick to the inside of the screen, and mount the transceiver on the handlebars next to the Zumo 550 all of which works brilliantly.

    Also come from Autocom over the last 6 years, but was so impressed with a loan of one with the bluetooth headset, I have just bought a new SR10 and SMH10 to slowly move over to. The Hirose connectors are a bit fiddly to stick a meter probe into and measure resistances ! Even Sena technical could not help me which I found disappointing, unless I got a trainee..

    I am over in the UK, 25 miles SW of London, bike is the FJR1300 and I like long tours - Scotland a couple of weeks ago and France next week

    Thanks again,

    Nick

    Just bought an SR10 to use with my Yaesu VX8DR. Followed the PDF I found to wire up the CT-M11 with the Sena SC-A0116.


    Paired the SR10 it with my bluetooth headset...


    It seems that PTT and the mic in my helmet seem to work just fine transmitting, but the VX8DR speaker audio isn't coming through bluetooth... still coming through the radio speaker, even if I double tap PTT to manually open the audio channel.

    Any ideas?

    This is my wiring for reference:
    CT-M11 - SC-A0116
    Black - Red
    Orange - blue
    Red - Black
    Green-390kohm-brown
    Blue-390Kohm-brown

    So it looks like the VX8DR uses the same type of waterproof connector plug that the FTM-10 radio's use. So that's not like a standard headphone jack plug where normally once you plug it in, all audio goes through that plug.

    Have you checked the menu settings to see if you need to change something? I know the FTM-10's have different options in their menu's as where the audio goes. Either the built in speaker, or the audio out or both. Maybe you have a similar setup on the VX8?

    Hmm, according to this, the Black is internal speaker disable and the brown is the speaker out on the CT-M11 side. I don't see where you ever used the brown on the CT-M11 side? - http://rctnotes.blogspot.com/2011/01/yaesu-vx-8dr-serial-interface.html


    Pin No. -- CT-M11 Wire Color -- VX-8 Description
    1 -- Orange -- Microphone and Push to talk
    2 -- Gray -- +3.3Vdc
    3 -- Brown -- Speaker OUT
    4 -- Green -- GPS TXD (CONTROL)
    5 -- Blue -- GPS RXD (NMEA)
    6 -- Red -- Ground
    7 -- Black -- Internal speaker disable

    Sonofa... you're exactly right, seems that the VX8 has a different pinout than the FM-10! (I was looking at a wiring diagram for the FM10).

    brb, getting out soldering iron. :)

    So looking at the VX8DR manual on page 14 (http://www.manualslib.com/manual/381863/Yaesu-Vx-8dr.html?page=14#manual), it shows a wiring diagram for packet use with the Black & Gray wire connected with a 22k ohm resistor and notes that if you want to disable the internal speaker for packet use. It does show the brown as the speaker out. I think you may have some wires wrong?

    Yep - looks like that's the trick, connect black&gray with 22kohm, then brown to red.

    Thank you for your help!

    Anyone used their SR10 with a ham radio since updating their Sena to 5.01?

    I had to use my SR10 to run my ham radio this weekend so it was the first time since I upgraded my headset to 5.01 that I had paired them up. Once I remembered how to put the SR10 into pairing mode, it seemed to work fine, but I had a problem that happened a couple times over the course of the day. 3 different times through the course of the day, I had the SMH10 shut off on me with no warning. Each time it happened, it was while I was listening to music on the SMH10 and then had the ham radio audio kick up through the SR10, however it didn't happen every time which was weird. The trigger seemed to be that I had music playing and then have the ham radio audio kick up through the SR10 which mutes the music, then I'd hear a few crackles and then silence. The first time it happened, I noticed my ham radio was feeding out audio, but I wasn't hearing anything on the headset. It took me a minute to realize that the headset had actually shut down. :eek1 So I paid attention and it happened again soon after that. When the headset would shut down, you wouldn't hear anything like the normal shut down notice. It would just go quiet. It's almost like the headset was crashing.

    It seems strange though because the headset works fine otherwise, it was only when I had music going and then have the SR10 audio kick in, but like I said, it didn't happen every time. Sometimes the SR10 audio would kick in just fine and the headset would mute, ham radio audio would play, then it would mute and my music would come back.

    During the course of the day working the event, I never had music playing on the SMH10 and the SR10 & SMH10 played nicely together without any hiccups.

    On the way home, I kicked on my music, and sure enough one more time, the ham radio kicked in and off went the headset.

    What puzzles me is what kind of signal is the SMH10 getting from the SR10 that's causing it to crash? Prior to this, I've been using my SMH10 for an entire 3 day weekend riding listening to music, had both cell phones paired to it, mulitple intercom conversations and never had an issue. I connect the SR10 and I'm suddenly having issues? I may have to send a note to Sena and see what they say? I think I'll start first though with resetting the SR10 and see if that helps as I had already reset the SMH10 after the last update.

    I'm interested in ditching my current Autocom//Yaesu FTM-10R hardwired setup. I just got started in the bluetooth arena with the new 20S headset.

    My friend and I are headed out to do the CO-BDR later this month. He's using a Sena SHM-10 and has an SR10 already. I'd like to know if there are any sticky points with my using the 20S and an SR10. We'd both be using the same radios, likely Yaesu HT's--I'm not sure which ones at this time. I've yet to purchase an SR10. Just can't find out from anyone whether there are issues with the 20S. So far, there seem to be a few issues with the 20S! He's had a pretty good experience with the SMH10 and the SR10 thus far.

    Thanks for any help and advice.

    The only problem I have is with the GPS plugged into the SR10, if your listing to music on your phone, it cuts off the first word the GPS says while its nailing up the Bluetooth connection. I think the same thing will happen if a call comes in over the radio.

    Anybody know an independent shop that will work, on my FTM10? I sent it to Yeasu and they sent it back and said it wasn't worth repairing. It'd take trouble shooting at the board level, which I'm sure Yeasu wasn't willing to do.

    Yep. Got the T10 out a few weeks after posting that pic and fixed it in 10mins.
