I’ve been studying for the Extra class exam and I realized that I need a new calculator. I haven’t owned a scientific calculator in years. There are so many to choose from these days. Which brands/models do you recommend? I used to own Texas Instruments and Casio. Which scientific/graphing calculators are the most versatile? Thanks in advance.
Most of the responses noted that pretty much any cheapo calculator will do. One guy suggested that he might find something suitable at the local dollar store. This is true—about a year ago, one of our club members showed up with a bag full of scientific calculators he found at a dollar store and passed them around. I use it now down in my shack.
Mark, K5LXP, had the best answer, though. He wrote, “Take one of these into your next test session and you’ll have the respect of the VE’s before you even begin.”
I love this! Not only is this a great picture of a slide rule, it actually works. By clicking on the scale or the cursor you can move them, and use this just like you would a regular slide rule.
Try it. You might like it.
