Abstract

Millions of dollars are lost annually on radio equipment due to theft and negligence. Any person using a hand held portable radio who has to leave the unit on a table, floor, OI in a automobile is at risk of losing the radio. This also applies to radios being stolen while unattended. This design concept is intended to minimize that risk.

LOST OR STOLEN RADIO OPTION

by James D. Goldsberry and John Rizkovsky

  Millions of dollars are lost annually on radio equipment due to theft and negligence. Any person using a hand held portable radio who has to leave the unit on a table, floor, OI in a automobile is at risk of losing the radio. This also applies to radios being stolen while unattended. This design concept is intended to minimize that risk.

  This option uses a small transmitting device to alert the user when they exceed a certain distance from the portable. The option can also be programmed to inform a dispatcher DI other personnel that the user has been separated from the portable. The portable radio design would have to include fixed priority scan and transmit signaling.

  The portable would scan for the signal from the transmitter. If the signal is detected the portable would resume scanning. If the signal is not detected the portable could be programmed to wait a predeter- mined length of time before it begins signaling the

operator with an intermittent alert tone. If the operator returns and the transmit signal is again detected the portable would return to the scan mode.

  In the event the operator does not return and the transmit signal is still not detected the alert tone would continue until it times out. If at any time the signal was detected the portable would return to the scan mode. The amount of time it is in the alert mode can...
