Good Moisture
Put damp rags on the tops of radios to keep them cool. Make sure the rags are
damp, not soaking wet. Soggy rags lead to water inside the radio. Some of you have
tried letting ice melt on top of a set. Don’t! That much water will get inside and do
damage. However, ice laid against a set can do some cooling without getting water
into the equipment. Try large plastic bags to hold the ice.
Before you put on the damp
rag or use ice on the sides,
make sure all screws are
screwed down tight and all
seals are in good condition.
Of course, whenever possi-
ble, shade your radio. Use
cardboard or your vehicle’s
canvas top. Anything will help
that keeps the glaring sun off
the radio, but doesn’t hold in
the heat.
Lessons learned have shown
that shade is a valuable tool
and that almost anything can be
used to give your radio some
shady relief.
A fan will run itself to death
trying to cool your radio. Give
the radio the moisture–and–
shade treatment to help the fan.
Overnight, condensation forms on metal surfaces that are
cooler than the air temperature.
This condensation can
affect electrical plugs, jacks
and connectors. If condensa-
tion is affecting your commo
connectors, tape over all con-
nectors that may be exposed
to moisture overnight. This
prevents that moisture from
contaminating the contacts.
Plugs should be dried
before inserting them into
equipment jacks.
