1) Make sure your radio is in top operating condition. Small problems (such as loose antenna connections, bad microphones, intermittent operation, etc.) may be just annoying during casual operation, but WILL cause major grief under the continuous/severe service of net/emergency operation.
2) Don't operate your handheld with it hanging on your belt. Using the radio while it's strapped to your waist reduces your effective radiated power by more than 10 dB. That's a 90% reduction in power. Hold the radio in your hand, with the antenna in the clear.
3) Regarding antennas, those 3" rubber dummy loads may be cute,
but you're throwing away 3-6 dB of power when using one. (If you're really into
math, compute the loss of a 3" rubber dummy load used on a beltclip).
A telescoping half-wave has a gain of as much as 10 dB over a 3" rubber
duck and a quarter-wave provides a 4-6 dB improvement. Even a 12-15" rubber
duck will boost your signal by 3-6 dB over the 3" ones. Remember that
one dB can mean the difference in whether or not a critical message gets through.
4) Have charged batteries and spare battery packs! If you also have
a dry cell battery case, fill it with alkaline batteries. Make sure you have
enough batteries with you to carry you through, even on high power.
5) Use headphones or an earphone rather
than a speaker/mike. Most earphones will plug directly into your HT. Low
cost stereo headphones are widely available and will work perfectly with
your HT using a mono to stereo adapter. The headphones also have the advantage
of concentrating the communications in your ears, while partially shutting
out the outside noise. Headphones will also prolong battery life by allowing
the radio to operate at lower audio output. A speaker/mike is the worst thing
you can use --- it doesn't cut the outside noise, it doesn't save batteries,
and where is that HT while you're using the speaker/mike?? (Hint --- see
#2!)
6) Speak slowly and clearly when transmitting! You make take pride
in your ability to run your words together and mumble, but the station on the
other end may be in a noisy environment and may not receive your message.
7) Check out your ability to use simplex. Even if the operation is
being conducted on a repeater, there may be "dead spots," the repeater
may go down, or, sad to say, there may be jamming. Even if you can only work
the two or three stations closest to you, a message can still be relayed. To
maximize your simplex range, please reread #2 and #3.
8) Listen to net control and direct all communication through him/her.
Identify your station when calling net control and keep all communications
direct and to the point.
9) If you must leave the radio or the area to which you have been
assigned, first seek permission and acknowledgement from the net control station,
make your "time off" as short as possible, and check back in with
NCS immediately upon your return.
10) Project a good image to the non-hams around you that are part
of the event/emergency. This means acting professionally, using basic hygiene
skills, etc.
