US Patent:

55949509, Jan 14, 1997

Filed:

Nov 23, 1994

Appl. No.:

8/344085

Inventors:

Charles R. D'Amico - Cambridge MA
David Blumberg - Manchester NH

Assignee:

Advanced TechCom, Inc. - Lawrence MA

International Classification:

H04B 1700

US Classification:

455 671

Abstract:

A radio communication system having, at a local station: a transmitter adapted to transmit signals to a remote station with a predetermined carrier frequency; and, a receiver tuned to a carrier frequency of signals transmitted to the local station from the remote station, the carrier frequency of the signals transmitted to the local station from the remote station being different from the carrier frequency transmitted by the local station to the remote station during a normal mode of operation and tuned to the carrier frequency of the signals transmitted by the local station during a test mode of operation. With such an arrangement, the carrier frequency of the transmitter at the local station can be tested by a receiver at the local station without requiring the use a the remote station and without requiring additional equipment.
