Advanced Radio Amateur Examination

Calculator


Let it be stated that "You DO NOT have to buy a calculator" but if you do want to buy one then consider what is witten here and make you own decision. Further if you do decide to buy a calculator then "You DO NOT have to buy any book(s) on how to use it", as this course will show you step-by-step what you need to know about the calculator.

When looking for a calculator it is best to seek one that will meet your needs not only for amateur radio but one that is also used in schools, colleges and universities, then it could meet your needs for years to come (assuming you do not break it !!) - or may be for another member of your family for that matter.
We have found from looking of the web that Casio fx-83MS (or the Casio fx-85MS solar power version) is suitable for schools, colleges, universities and amateur radio calculations and so this is the calculator that we will be using in our pages.
Such a calculator would make an excellent Birthday or Christmas present and is available (as at 31st Jan 2004) for about £7.00. Below it is shown in its packaging as in UK.

However if you are a student younger than 11 do not be put off, if you have reached this far in amateur Radio then it should be well within you understanding.

Please note that:- Candidates must accept full responsibility for ensuring that their calculators are in working order for their examination and that the use of material stored in a pre-programmable memory could constitute cheating.

Spare battery

ALWAYS have a spare battery with you and know in advance how to fit it, you will need to have a small screw screwdriver with you! If the calculator will not tunr on  or if the display becomes dim then a new battery should solve the problem. To continue to use the calculator may result in errors in calculation.

The battery required is a LR44 which is an Alkaline cell of 1.5V - also known as AG13, G13A, LR1154, L1154, RPX675, D76A, V13GA, PX76A, PX675A, GPA76, 1128MP, 1166A, S76, cost about £1.75 - KEEP a SPARE - DO NOT SHORT out the contacts.
