Q |
What is the difference between a NiCad, NiMh, Li-Ion? |
| |
|
|
A |
There
are three types of batteries used in portable two-way radios;
NiMh, NiCad, and Li-Ion. NiCad batteries are the most common
batteries used, NiCad is short for Nickel-Cadmium. NiCad
batteries are rechargeable and inexpensive, and when treated
right, will provide many thousands of charging cycles, however
if the proper charging guidelines are not followed, the battery
begins to develop what is known as a memory effect, and does not
allow the battery to become fully charged, thus drastically
shortening battery life. NiMh, or Nickel Metal Hydride
batteries are slightly lighter and smaller than NiCads, and are
appearing in more and more devices. Unlike NiCads, NiMh
batteries have no memory effect, so charging the battery before
fully discharging it causes no mal-effects. Li-Ion, or
Lithium-Ion batteries are a very new technology just coming
about in the industry. Li-Ions are the smallest, lightest,
longest lasting batteries available, however not all equipment
supports their use, and they are very expensive. |

Q |
How long do batteries last? |
| |
|
|
A |
The
amount of energy a radio is using is the current. A battery is
typically rated by how much current can be drawn over a specific
amount of time. The more current a radio is pulling, the more
energy is drained from the battery. A radio uses very little
power while turned on doing nothing, but when receiving, more
power is used, and a substantial amount of power is used to
transmit. For example, if a radio that pulls 50 mah was tuned
to a local weather information loop, and was always receiving,
and the radio had a 1000 mah battery you can figure out
approximately how long the battery would last. One thousand
(1000) mah (milliamp hours) divided by 50 mah, is 20, or 20
hours of operation. Again, your radio uses more power
transmitting than receiving, so the more you transmit the
shorter your battery will last, and the less you transmit and
receive the longer your battery will last. |

Q |
What is the difference between 12.5 & 25k spacing? |
| |
|
|
A |
Conventionally, radios have used 25 KHz spacing, so if you owned
2 frequencies right next to each other, you may own 861.0150 MHz
and 861.0200 MHz, but now under the new 12.5 KHz spacing
regulations, in that space, you could be assigned frequencies
861.0150, 861.01750, and 861.0200. This change allows for more
effective spectrum management. |
