	I had a radio application that required extreme range. The best way for me was to go for an off-the-shelf device. Here are a few simple systems that are available. www.Coronis-systems.com 500mW 5km 4.8-100kbp Wavenis radio system www.rfsolutions.co.uk 458MHz 3-4km radio system __________________ jack of all trades
