Amateur radio calculators for antenna length, Ohm's law, resonant frequency, grid square, and effective radiated power. The ERP calculator can be used to determine if an RF evaluation is required for a ham radio station and shows the PEP and ARP power with the entered parameters. The grid square calculator can convert an entered lat/long to grid square, or can use your GPS to find your current location and grid square.
