M any amateurs carry an HT as part of their daily
routine. Those who do so, should always include
basic accessories such as an extra NiCd pack,
external power cord, some sort of gain antenna,
comfort and safety items “just in case.” All it takes
is your battery to “die” when you need to access
the auto patch to report a traffic accident, get lost
or break down on the road in an unfamiliar place
to fully appreciate the value of being “prepared.”
A minimum “ Go- kit” should sustain a day of
continuous operation and be easily supplemented for
overnight trips. The bare essentials are a 2-meter or
dual-band HT, some sort of “ gain” antenna, auxiliary
power source, writing materials, comfort and safety
items. You can do a lot with a minimum kit, if you
plan carefully. There is risk of not having something
you may need if you go too light, but obvious “ bells
and whistles” should stay home. My “every day” kit,
including a dual-band HT, weighs 5 pounds and is
4”x6”x10,” fits in a waist pack and contains:
1)

The best “ Go-kit” for you won’t fit anyone’s canned
list. Assemble one which fits your routine, experience
and local conditions. Commuters using mass transit
should keep at least bare essentials handy. A larger kit
is practical if you are usually near your car. The trunk
is the best place to store emergency gear because it is
dry, accessible either at home or away and relatively
secure. I have three kits which supplement each other.
My “ every day” kit fits in a briefcase and accompanies
an HT.

A “ backup” shoulder bag in the car provides basic tools
and first aid supplies, some cash, a spare HT, 25w
brick amp, coax, antenna, gel cell battery and
accessories for 24 hours operation. I also carry a fire
extinguisher, first aid kit, blanket, two MREs and a
gallon of water in the car. Two “ evacuation bags” at
home have three days supply of food, water and
medications, a boxed non-spillable AGM deep cycle
battery, battery charger, tool kit, rain gear, clothing,
safety and shelter items.
In rural areas, fire making supplies, pocket knife, map
and compass should be in your kit. In the suburbs,
keep a local street atlas, change for a pay phone and
some emergency cash or credit card. A compact,
sturdy flashlight, extra batteries, first aid kit, extra HT
battery pack and spare eyeglasses are useful
everywhere. If you take require prescription
medications, carry a 3-day supply. On the road also
carry enough cash for a tank of gas, hot meal and a
room.

The ”Backup Bag” carries “ 24-hour” items in a sturdy
shoulder bag or lumbar pack with carrying strap. Mine
has external pockets marked as to contents. The large
main compartment carries a 7ah gel cell battery and
20w brick amp while other items are packed around
and between them. It stays in the car until needed. I am
trying to reduce it from its 12"x8"x6" size and 18 lbs.
weight. Suggested contents are:

Neck-lanyard pocket with spare car keys,
emergency cash, credit card, long-distance calling
card and RACES ID.

brick amplifier and HTs.
6)
10 ft. AWG10 gage extension cord, with battery

Today’ s compact HTs are rated for only 20% duty cycle at
5w output, or 30 seconds transmit to 2 minutes of standby.
Their final power transistors may fail prematurely if
subjected to frequent full power transmissions of several
minutes. When I first got my license, I burned up three sets
of finals during the warranty period of an HTX 202. The
Kenwood TH22 I replaced it with later fared no better.

Kenwood’ s service center admonished me that I was
exceeding the recommended duty cycle for their HT and
should buy a mobile, which I did. I also sought full-sized,
rugged HTs with adequate heat sink, built to public safety
standards for RACES use and pass that advice along. Unless
you know that your handheld is, limit your use of full power
to short transmissions.
A small brick amplifier is also recommended to provide
better range and signal clarity from your HT. Good
operating practice and maximum endurance on battery power
demand that you limit RF output to the minimum needed to
maintain reliable communication, but the emphasis is still on
“ reliable.” An ideal portable amp for EmCom should weigh
no more than 1.5 lb., provide 10-15w output when driven by
the HT on a low, (battery conserve) power setting and 2545w when driven by the HT at full power from its regular
NiCd battery pack. The amp should not require no more
than 8A current at maximum output, enabling it to operate
safely from a Series 1545, .093 pin Molex connector and
fused cigarette lighter plug. No preamp is wanted, because
preamps FM just increase intermod. It is more important to
buy a rugged, quality amplifier with an ample heat sink than
to seek the smallest “ box.”
Disaster Bags-- are duffels of family survival gear
stored above flood level in your house to shelter in
place which can also be grabbed quickly and thrown
into the car with the backup bag in the car trunk, if
needed. Many hams overlook these, but in a real
disaster, they will be are your most important item.
Each family member needs their own evac bag with
personal medications, warm hat, rain gear, sturdy
shoes, a change of warm clothes, socks and underwear,

flashlight and sleeping bag or heavy wool blanket in a
soft backpack. Store in sturdy, waterproof containers,
with handles, such as metal trash cans, with a 3 day
supply of nonperishable food, water and sanitation
supplies, so the family can take when told to evacuate.
Establish a refuge or safe meeting place within
walking distance of your home, work or school at a
friend or neighbors if family members can’t get home,
or must leave for their personal safety. Arrange with
an out-of-state friend or relative to accept collect calls.
Family members should meet at the refuge or call the
out-of-state contact when they reach another place of
safety. Sew tags in children’s clothing with your
address and telephone number. Label home telephones
with YOUR address to ensure that visitors calling from
your home can tell emergency services where they are.
Install a flashing porch light so that the responders can
find you. All family members must know the
emergency contact phone and address! RACES

1 gallon of water per person/day is needed for drinking
and washing. Good emergency foods are canned soup
or stew, beans, tuna, juices, fruits, veggies which can be
eaten cold, or warmed without preparation; also peanut
butter, cheese spread or jam in plastic jars, lots of hard
candy, instant coffee, tea, dried fruit, crackers. Avoid
processed meats such as Spam which are loaded with
salt or fat and hard to digest. Sterno, heat tabs or MRE
heaters are best for warming. Use up and replace
emergency food and water stocks every six months.
