Hey guys... sorry I haven't posted here in a while.
I have a Chatterbox on my helmet. I would recommend that over the motocom deal. It is about the same price and it works very well.
However, the problem was that I was not ready to spend $120 each for my wife, and two sons. That's where the FRS radio deal comes in (by the way, chatterbox IS an FRS radio).
I bought CHEAP FRS radios from Wal Mart - $25 for a pair. The radios should have seperate jacks for headset and mic. Then, I bought CHEAP computer headsets from Wal Mart $15 a pair. And this is what I did:
First: physically mount the headset. I used a dremel tool and a pair of wire cutters to cut away the whole headset deal except the speakers and mic boom. Some imagination, sticky velcro and tie wraps got those mounted. There is a lot of stuffing involved with shoving the excess cord under the helmet cushions.
Next: mount the radio. Sticky velcro on the back of the radio and the back of the helmet. A couple of sticky plastic hooks on either side and rubber bands secure the radio to the back of the helmet. I wanted the radio to be attached to the helmet for convenience.
The speakers plug right into the headphone jack. A mono to stereo adapter had to be used for both speakers to work.
There are several methods used for externally keying the mic. Some key when the mic circuit is completed. Some use the third connector on the mic jack (I had both types of radios). A little experimenting will go a long way. As for the PTT button, just use any button that can be strapped to the handle bar (i.e. an old kill switch).
If anyone wants details on part numbers etc or pics, email me at
JIMnJILL@mchsi.com. I'll help out however I can.
This radio setup works really well. However, it has limitations. You can't expect to talk on it while riding a MX bike at WOT. I really like mine and would hate to ride with the family without them.
