Working channel equipment 14(1) transmits and receives working channel information over a temporarily assigned RF working channel. Control channel repeater 14(N) transmits and receives control channel information over a dedicated RF control channel.
Base station equipment 10 in this example includes at least one repeater 14(1) for transceiving working channel information, and at least one repeater 14(N) for transceiving control channel information. Receive information such as voice or data. In general, base station equipment 10 wirelessly exchanges digital control information with terminal 10, and temporarily assigns a working channel for use by the terminal to wirelessly transmit or H04W84/08- Trunked mobile radio systems.H04W84/04- Large scale networks Deep hierarchical networks.paging networks, cellular networks, WLAN or WLL H04W84/02- Hierarchically pre-organised networks, e.g.229920003258 poly(methylsilmethylene) Polymers 0.000 description 1.238000006011 modification reaction Methods 0.000 description 1.238000006243 chemical reaction Methods 0.000 description 2.230000001131 transforming Effects 0.000 abstract description 3.230000001702 transmitter Effects 0.000 claims description 3.230000005540 biological transmission Effects 0.000 claims description 4.Publication of WO1999007169A1 publication Critical patent/WO1999007169A1/en Links Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)

Having the antennas as widely separated as possible will help, but not eliminate some range reduction. are some examples of these types of receivers. Having multiple units, operating on the same band, in the same vehicle, can cause reduction of range in both units, even if using spread-spectrum techniques. Some receivers have telemetry and/or video transmitters integrated. Receivers Having Telemetry/Video Transmitters Integrated ¶
#Dual receiver radio serial
Otherwise an external inverter must be used between the receiver data output and the Serial Port’s RX input. Autopilots using F7/H7 cpus have the ability to invert the RX input via its SERIALx_OPTIONS bitmask. Some protocols, like SBus, require that the signal be inverted. It is important that all receivers be configured for no pulses for radio loss failsafe for the changeovers to work properly.
