Bike to bike intercom?

[Mick-H]

I've had a Cardo Scala FM for a good few years and I'm very happy with it, listening to music and phone call are both very clear up to 70mph above 80 it's not as good and I find I have to almost shout to get myself heard, I reckon this is in part due to me not having the mic in exactly the right place and turbulence from the screen.
A good read source of info
