Engineer - Version 3.0 ENGINEER version 3 Calcuates Resonant frequency, Reactance, Wavelength and much more. It calculates resonant frequency from any combination of L,C and F and calculates XL or XC. All questions and answers are in correct units for pico, nano, micro, mili, Kilo, Mega and Giga. Converts wavelength to frequency and frequency to wavelength and shows free space sizes for 1/4 wave, 1/2 wave, 3/4 wave, 7/8 wave etc. Calculates WAVEGUIDE wavelength for all WG/WR numbers and displays min and max frequencys for the chosen waveguide and calculates dish gain. This program covers from VLF to Microwave has configurable colours.
