I administer license exams. We always encourage those who do well on their<br>
technician exam to take the general exam. Recently two candidates, who did not<br>
plan to take more than technician, also passed the general. Both left in a mild<br>
state of shock. Not everyone passes, but it is good practice.<br>
<br>
Two numbers to remember:<br>
<br>
300: speed of light in millions of meters per second. Divide 300 by MHz and<br>
get wavelength. Divide 300 by wavelength in meters and get MHz. Half of the<br>
wavelength gives you the length of a half wave dipole, etc. A meter = about 40<br>
inches or about 3-1/4 feet.<br>
<br>
7: We have bands starting at 7, 14, 21, 28, and 3.5 MHz. CW and data in the<br>
lower part; voice and image in the upper parts. Get the colorful frequency<br>
chart from ARRL:<br>

That will give you another way to look at amateur allocations. I keep a copy of<br>
that chart near my radios. I can't remember all those numbers either.<br>
<br>
The technician license question pool changes somewhat on 1 July. If you know<br>
the material, you would still pass, but<br>
<br>
Good luck,<br>
