The most common max power on a new radio is 100 watts, although some of the more expensive radios could have more. With the stock 100 watt radio, depending on atmospheric conditions, your antenna type, and the height of your antenna, you could talk to most all countries, but not on demand. What I mean by demand is that you can't control when you will make each contact, but each day, or night, you may contact some part of the world.
1 In addition to specific course and scholastic average requirements, each candidate for a bachelor's degree from the University of Illinois at Urbana-Champaign must earn at least 60 semester hours of UIUC credit, of which as least 21 hours must be 300- or 400-level courses at this campus (Student Code Art 3-801).
The Graduate School recognizes nine semester hours during a long session semester and three hours during a summer session as a minimum full-time course load. Individual graduate programs may require more. The three semester credit hour minimum course load for the summer session may be satisfied in one six-week term, or in the nine-week or twelve-week terms. Students enrolled in Affiliated Studies are considered full-time students. The maximum course load for a graduate student is fifteen semester hours in a spring or fall semester, or twelve semester hours in a twelve-week summer session. you will need to find out from your school how many credits are needed to be considered a full time student. i feel 15 credit hours is very reasonable.
