Surely someone has had to find this before? http://www.radio-match.com/tech.htm A little expensive, but if you can't make one what are you to do? Comments?

I've handled that unit at trade shows. It will do the job, but it's a bit limited in range. When we bought our wireless firing system, we chose this system (http://www.pyromate.com/gigalinkwirelessfiringsystem.htm) instead as we wanted greater range and more hits. Bought ours last August, no complaints, used it on 3 shows last summer.
