But the poor guy with the small backyard antenna will not be able to reach 100mW ERP. Maybe a "OR" limitation would serve best: 20W TX power or 100mW ERP (meaning: you can use whatever power needed to get 100mW ERP but if you reach 100mW ERP with less than 20W you can "pump up" to 20W) 73, Rik ON7YD Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
