The system would consist of: a two-way conventional, direct only configuration. Many two-way radio users are licensed to operate on a single frequency. They may also operate with a mobile radio for normal vehicle operation, and with a portable radio when away from the vehicle. At times, when the user is away from the vehicle using the portable, there is a need for momentary high power operation to communicate to a second user or group of users. This high power operation is not possible with the portable. Other user/s between user 1 and 2 may be used to relay the message. This relay mechanism can cause the message to be delayed indefmitely due to human error or misun- derstood by incorrectly relayed information. The user could also return to the vehicle and use the higher power mobile, although this would require leaving their current location or leaving repeatedly if more than one message needs to be sent. Since the user is licensed for only one frequency, this prevents normal repeater operation or vehicular repeater operation.
