The amateur repeater is a means of greatly extending the range
o f Ill Vi
oi nem. eouinment commonly used for local emmunieations.
The nominal range -of such equipment between mobile units •
is about 15 miles, but this is increased to 100 miles by
the repeater (50 miles in any direction from Bryan-College
Station). This greatly increases the utility of the equipment
for all types of local conmunications.
The repeater is a non-profit amateur project sponsored only
by the amateurs and concerned local agencies, such as Civil
Defense. Whereas the equipment cannot be used directly by
CD personnel, the Radio Amateur Civil llmergency Service nrovides
reliable comnunications for Civil Defense as has been demonstrated
in many instanc=.
