drawback of requiring twice as much air time to carry out a conversation, as each

transmission is repeated back. However, its simplicity and low cost makes it

perfect for temporary or emergency use, and to provide coverage in areas where

the cost of a duplex repeater can't be justified.

For many radio clubs and emergency response organizations, a single semi-

portable duplex repeater is a major investment. Simplex repeaters like the ADS-

SR1, on the other hand, are inexpensive enough to be kept as individual

equipment for each member, making it more likely that they'll be available for

rapid deployment when needed. An emergency repeater station can be set up

with nothing more than a handheld radio, a cable, and the repeater unit itself.

The ADS-SR1 has additional features that make it useful as more than just a

simplex repeater. For example, the 'say again' feature can be used to repeat a

single missed message on demand, even with the normal repeater function

disabled. This is particularly useful in situations where most stations are close

enough to hear each other directly and normal operation of the repeater would

be distracting.

The voice announcement features of the ADS-SR1 can be used independently of

the repeater functions, and can be used for such things as club activity reminders

or foxhunt beacons, or even a slow-scan TV beacon. The voicemail feature

functions like an answering machine for your radio, recording up to 20 incoming

messages and allowing them to be retrieved with a separate access code,

independent of the main security code.

Legal Issues

Legal restrictions on the operation of a simplex repeater depend on the radio

service used (i.e., amateur, commercial, FRS, MURS, etc) and vary from country

to country. Interpretations of specific rules vary as well, and their applicability

to operation of the ADS-SR1 may depend on which specific features are used. It

is the responsibility of the end user to ensure that they operate within applicable

regulations.
