Transmitter turn-on time (TTO) is defined as the terminal users, since it directly affects the inbound chan- time required from the instant that a Push-to-Talk (FIT) nel utilization and capacity. It is difficult to minimize is asserted to the time when the transmitted signal is data-mode lT0 in a two-way radio that is to be used folly stable and usable by a receiving unit. selectively for voice or data communication. In particu- lar, an efficient and cost effective method of reducing TTO can also be referred to as transmitter attack the effects of load pulling of the transmitter frequency time, and receiver-to-transmitter switching time when on TTO without degrading voice mode transmitter per- applied to a simplex radio transceiver. formance is needed.
