好牛啊,5分钟100%的正确率。这个分数在俺小学一年级听写字母得满分以后再也没有得过......

老大过奖了,这些题一半是靠运气。再考一次肯定不会100%了。

不过已经没有时间再弄g了,剩下的几天突击extra的题目,总觉得时间不够用。

从technician考起,通过后马上可以考general。如果再考过,就可以考extra。
有能力你就都准备好。你参加吗?如果能考过extra,crsa给你升到一级,呼号换ba

这,是真的吗?

哎,刚才试了一下,t和g很容易,猜猜都过了,e看来不看一遍还是不行,差一道题,没过!

beryllium oxide = beryllia = 氧化铍

复习中被坐标系各种计算弄的头晕。这道题不知道如何解,哪位老大帮忙给看看?

e5c16 (b)
in polar coordinates, what is the impedance of a circuit that has an admittance of 7.09 millisiemens at 45 degrees?
a. 5.03 x 10 –e05 ohms at an angle of 45 degrees
b. 141 ohms at an angle of -45 degrees
c. 19,900 ohms at an angle of -45 degrees
d. 141 ohms at an angle of 45 degrees

极坐标不是逆时针是正值吗?而且已经说是45度了,为什么算出的阻抗是141欧,负45度?

还有,考试中允许使用计算器吗?

导纳和阻抗的数值是倒数关系,哥们,他们的角度当然不同
考试用不着计算器。如果取得许可要带进计算器,不许有函数计算功能。即使需要计算,简单的加减乘除就足够了。需要的话,考场提供草稿纸(交卷时一起交上)。

谢谢aj,已经明白了。 没有函数的计算器基本上没有什么用,那就不带了。 :)

radioexam这个是老题吧?2002年的。

我觉得eham的题有些太单一,翻来覆去就那么几道。qrz.com的还有以前做的http://www.hamtestonline.com/的还好些。

john, n5jb and i have arrived in beijing

i have been watching from usa, hellocq does not allow posting from outside china.

i congradulate all who have prepared for this exam.

i want to thank everyone who help make this exam possible and especially bd1byv to provide exam room, n5jb to make long trip to help make this possible, and ab7py/ba1aj to manage all things in beijing.

i wish all of you good fortune to pass exam.

i look forward to meeting all of you friday or saturday.

some notes on takeing exams

rest well before exam,

bring a photo id. be sure to create the frn before comeing, it will help if you fill out form 605 before you come.

there is not time limit on exam. take your time. no hurry.

calculators of any kind are allowed, they must have memory cleared before exam.

no books or study materials are allowed in exam room. cell phones and pagers must be off ( and hand held radios ).

can not leave the exam room untill all test materials is given to the ve, sorry no bathroom breaks during the exam.

while exam is in progress, three (3) ve must be in exam room all the time.

once each person has finished, give materials to ve and leave the exam room, you may wait outside and rest.

three ves must grade the exam. then will notify candidate of score.

you must pass element 2 before takeing element 3, and pass element 3 before taking element 4.

you may rest and study between exams.

you do not need to pay fee for second exam if first exam is passed. one fee is ok to pass all three exams.

you may re-take exam if not passed, however must pay exam fee again.

if you select answer do not change answer unless you are very sure that first answer is not correct, usually first choice is correct. i see many times where people change answer and first answer was correct.

we have two days of exams, take all the time you wish in between to study and prepare for next exam.

no one will know which question missed. every test is different,

ve only checks answer key and reports score.

it will take one week to receive us call sign, if already have call sign, and pass next level, upgrade is immediate

number in call sign will be based on address used in form 605 application.

the ve's all wish you the best and have taken great effort to make this possible.

again thank you for participating in first ever exam in all of china.
