I've got an Autocom, Pro-7 Sport, and hubby has the Starcom1 system.
Hubby (guitardad) wrote a response to someone asking about systems on MC-USA.
"OK, as LL said, we've both installed comm systems on our bikes. Mine is a Starcom 1 (
http://www.starcom1.com) and hers is an Autocom Pro-7-Sport. Looking at the Autocom site, apparently the Easi-7 advance doesn't support bike-to-bike communications and the Active-7-Smart doesn't have an option for battery power - it has to be wired to the bike. The Pro-7-Sport has the option for battery or hard-wired, but you have to plug in a little wiring harness, so it's not easy to switch between battery and wired-in. Here's our experience with the units....
We're using a pair of Motorola FRS Talkabouts, and they seem to work fine with both comm units. Each system has a Push-To-Talk button, that we've attached to the left handgrip. The Autocom unit has a switch to select PTT, Vox (Voice-activated to talk), or always transmitting. This caused a little problem during our rainy ride to Tennesee - LL's switch got water in it, and defaulted to always transmitting, which meant she couldn't hear me!
The switch was replaced under warranty, and we haven't had any other problems with the unit.*
Both units have noise cancellation built in, and both raise the volume as background noise (read "wind noise") increases. The noise cancellation works well on both - neither of us can hear wind noise in the radio, but I wish the amount of volume increase could be turned up a bit more. Both allow you to adjust the Vox setting - the volume at which your voice turns on transmitting. We rarely use that, since I sing when I ride ( ) and so use the PTT. The Starcom1 has a volume adjustment as well, a feature the mid-priced Active-7-Smart has but the higher-priced Pro-7-Sport does not. The Autocom turns down the volume on any music source when either a 2-way radio or the "cell phone" input goes active. The Starcom1 shuts the music off completely. Both of us have Roady2 XM radios installed as well, and both seem to work just fine. The connectors are incompatible - when I rode her bike, I couldn't plug the neadset in my helmet into her system.
Now for price - I paid under $300 for the basic Starcom1 setup from California Sport-Touring (
http://www.casporttouring.com/) while the same setup from Autocom was over $500. Now that the Autocom is on sale, it would probably be about the same price. Autocom's accessory cables are more expensive, as are the extra headsets if you want to hook up a passenger. The cables are also beefier, so they may stand up better over time. Autocom has been around longer, and has a good reputation, but I've been satisfied with the Starcom as well."
* We rode in the rain again on Saturday, and my new PTT switch gave up after about 30 minutes. Maybe what I need to do is install handguards on my bike. Once the switch dries out, it works again, but this is a REAL PITA.
