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 continuos/severe service of net/emergency operation. If your radio's not in top shape, buy, beg or borrow one.

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 your throwing away 3-6 dB of power when using one. A telescoping half-wave has a gain of as mush as 10 dB over a 3" rubber duck and a quarter-wave provides a 4-6 dB improvement. Even a 12 to 15 inch 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 message gets through.

4) Have charged batteries and spare battery packs! If you 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/mic. 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 outside noise. Headphones will also prolong battery life by allowing the radio to operate at a lower audio output. A speaker/mic 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/mic? (Hint - see #2)

6) Speak slowly and clearly when transmitting. You may take pride in your ability to run your words together, 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 to 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 were assigned, first seek permission and acknowledgment from the net control station, make your "time off" as short as possible and check back in upon you return.

10) Project a good image to the non-hams around you that are part of the event/emergency.
