Bike to bike comma with autocom and bluetooth

[haydw]

Am about to do a long distance trip with a few mates and need to be able to talk to each other. A couple of us have autocoms, one has a starcom and a couple have Bluetooth systems, n-com and something similar. The autocoms and starcom can use pmr radios, but as my autocom SPA kit hasn't got a Bluetooth module (my zumo is wired and mobile BT to zumo) is it possible to get a Bluetooth module and then run bike to bike? What's going to be the best way for us all to communicate? Mobile phone is too slow and cant reach us all. Especially in the middle of Scotland. Any suggestions?

No cheap solution, with that mix PMR radio is the best option, but the riders with the bluetooth would need a bluetooth PMR radio like the Tribe, still a bit hit and miss due to bluetooth pairing but probably the cheapest option.

I'm working on same the problem myself and have come up with this solution. Not cheap but it works.
I've got the following kit:
Autocom SPA Duo
Bluetooth module (BTM02A) wired to Aux3 connected to my Phone / GPS
Kenwood TK3302 wired in to Autocom Aux1 with part number 2342

As I ride without pillion I've set the dip switches for Aux5(passenger phone) to amplify audio to both Rider and Passenger
This allows to me to both send and receive audio from this port.

Now for the not so cheap bit.

I picked up a Sena SMH-10 and the SMH-A0304 Helmet Clamp and a Splitter Adapter that breaks out the TRSS (4 pole 3.5mm jack) to headphone and mic sockets. Updated the firmware to 5.1.1

Reason behind Sean SMH10 is that its the only bluetooth device I've come across that support a feature known as universal intercom. This allows me to pair with other branded Bluetooth comms kit that other riders may have. It gives me maximum flexibility.
Now for the fun bit....
Took out my trusty warranty voiding devices and took the helmet clap apart. The mic is simply soldered to two points on small pcb and nicely labelled Mic + and Mic -
De-soldering this and soldering on a diy 3.5mm audio socket pigtail to the pcb, filling the gap with some silicon to maintain weatherproofing leaves me with a clamp that now has a mic in and audio out socket.
Next step is was to simply wire 2x 3.5mm audio extension cables from the helmet clamp to the splitter connected to Autocom Aux5.
I've got the helmet clamp clamped on to a Ball Flat Surface Adapter clamped to a handlebar mount. This means I can manipulate the smh10 if needed while riding. I can also wire a micro usb charging cable up in to have the smh10 charging while I ride. When I stop off to refuel for me or the bike I can simply remove teh smh10 form the helmet clamp.

This setup give me
ptt with two way radio when needed
full duplex comms with my phone if needed
full duplex comms with smh10 bluetooth comms kit when needed

All of this wired in to Autocom SPA and a single headset. Nice and neat.

Best of luck with your solution and Scotland is a great place to ride !!
