UPDATE:
SENA had posted a firmware update for the SMH10 Hub the other day and after I D/L'd it and installed it I was receiving reports that my transmitted audio over my ham radio had gotten lower... so I looked at the new firmware update and it now includes adjustable microphone gain for the two-way radio interface.... the microphone gain DOES NOT change the SMBH10B's microphone settings, so if you don't use a SMH10 HUB for your two way radio in addition to the SMBH10B Helmet Bluetooth headset, this won't make any sense to you...
I set the microphone gain to the higher setting, and now all is as it was before.... people I talk to on my ham radio, can't believe I am on my Goldwing on the Long Island Expressway (usually at night) doing 65 MPH and chatting away with them as if I were sitting in my car or god forbid in my house (I DON'T "play radio" from home, just while out driving around) because I sound THAT good...
Looking forward to others reports about their SENA stuff and how much they like it..
