Using Casio Calculators to calculate wavelength for radio amateurs. Which modern calculator is difficult to use for this. The Casio FX-991CW classwiz gives incorrect answers until you use BIDMAS entry which is really awkward compared to the existing non classwiz calculators.
If you want a modern calculator for these types of radio or engineering calculations, stick with fx-300ES Plus or fx-570ES Plus2 style calculators etc, steer clear of the Casio calculators with model numbers ending with CW. Look for the EXP button and the x10x button type calculators.

    Why are the solar cells covered, if I may know?

    Well explained my friend. I think I'll stick to 300,000,000 / 14,200,000 on my calculator. Wait - I need a bigger calculator LOL. 73

    The problem with 991CW is you have to use parentheses everytime, that is be very specific.
