Abstract

Portable radio users ofien utilize signaling to con- tact specific units. This device provides the ability to perform this signaling in either a noise free envi- ronment or a loud area that would mask normal methods of signaling. The units location in the remote microphone allows the user to purchase an accessory that might already be subject to purchase.

TWO-WAY RADIO SIGNALING THROUGH VIBRATING MOTOR IN EXTERNAL MICROPHONE

by David H. Karl and Bob Schukai

  Portable radio users ofien utilize signaling to con- tact specific units. This device provides the ability to perform this signaling in either a noise free envi- ronment or a loud area that would mask normal methods of signaling. The units location in the remote microphone allows the user to purchase an accessory that might already be subject to purchase.

This device utilizes common signaling methods found in portable radios. The signal is transferred,

through a series of flexes and interconnects, to the electric motor (typical vibrating device as found in pagers) which is housed in the two-way radio remote microphone. The motor current source (user replace- able cell), located in the remote microphone, is charged continually by the radio. The flexible cord of the remote microphone allows the user to locate the assembly as required for maximum vibration to the body.
