Modular Communications System Including A Portable Unit Range Extender And Selective-Call System

View page
US Patent:
50739727, Dec 17, 1991
Filed:
Jan 12, 1989
Appl. No.:
7/296514
Inventors:
Robert K. Tendler - Chestnut Hill MA
Frank P. Karkota - Westford MA
International Classification:
H04B 116
US Classification:
455 35
Abstract:
A method and apparatus for extending the range of portable RF transceivers and for providing a select-call system includes a hybrid remote control system to extend the range of a portable transceiver and to permit the operator of a vessel or vehicle to communicate hands-free through the utilization of his own full power base station and antenna, in which a modified full duplex system is used to control transmit and receive cycles from the portable unit so that the system can operate regardless of interference on the channel to which the base station is timed. Also provided is a selective calling system in which a recipient's transceiver is turned on by the transmitting transceiver through punching in the recipient's call letters or at least its address. As an added feature, the transmitting station automatically transmits its own call letters which are displayed at recipient's receiver. This system thereby quiets all receivers until the particular transceiver is digitally addressed.

Superheterodyne Sca Receiver And Method For The Manufacture Thereof

US Patent:
50239333, Jun 11, 1991
Filed:
Oct 13, 1988
Appl. No.:
7/257512
Inventors:
Frank P. Karkota - Westford MA
International Classification:
H04B 110
US Classification:
455 45
Abstract:
An SCA receiver is provided which has a close to ideal passband characteristic which greatly improves frequency response to produce a brighter sound due to the use of ceramic resonator elements. The use of ceramic resonator elements and a superheterodyne approach also provides a receiver which can be rapidly aligned and which has improved noise protection, lower distortion, increased stability, less residual subcarrier in the audio, and more consistent performance from one unit to the next. In one embodiment the superheterodynes circuit operates at 455 kHz which up-converts the usual 67 kHz signal by mixing it with the output of a ceramic resonator controlled local oscillator/mixer. The ceramic resonator and ceramic filter along with the local oscillator/mixer I. C. provides low group delay, improved impulse noise rejection, while most importantly achieving at least an order of magnitude better audio response over the signal bandwidth.
