5. There is a plug specifically for the CTCSS board The CTCSS encode also has an encode hang timer in which the time is programmable When designing the Linker IIa we worked hard to provide a product that is easy to use durable and of excellent quality at a reasonable cost The Linker IIa has many unique features One such feature is the control receiver input This input is unique in that it provides a level of control normally only provided on more expensive controllers It is optional to use the Control receiver input as the repeater receiver input port 1 and even the link remote base receiver input port 2 will provide the access to control the repeater The control receiver gives you control over the repeater even if the repeater s receiver is inaccessible Also with the addition of a resistor you can pass the control receiver audio to the repeaters transmitter audio output port 1 and the audio level can be adjusted with the control receiver input audio pot The control receiver COS can be set to switch between 1 and 9 volts and the polarity can be easily set as well When the control receiver COS becomes active all the port 1 and Port 2 DTMF signals are ignored and the Linker IIa only listens to the control receiver for DTMF codes The repeater Port 1 input has priority over the remote base link receiver Port 2 This allows for priority control with the control receiver Another such unique feature is the remote base control system whi

50. inker IIa controller is straightforward First you will need to determine a way to get a COS signal from your remote base radio The Linker IIa s RX 2 COS input can read voltages from 1 to 9 volts with a positive or negative polarity While the RX 2 COS input will read from 1 to 9 volts you can apply a voltage of 0 to 40 volts to it The COS signal also needs to be able to operate with the Linker IIa s approximate input impedance of 100K The Linker IIa s COS inputs are preprogrammed to be positive acting and the CTCSS inputs are also preprogrammed to be positive acting The COS and CTCSS inputs will both switch at about 2 5v from the factory IF and only if you need to change the polarity or the switching voltages the Linker IIa will allow you to do that without adding external circuitry Please see the SET RX 1 VOLTAGE Function 79 and 80 for the repeater inputs port 1 and the SET RX 2 COS VOLTAGE Function 81 and 82 for the remote base link port 2 inputs You might also want to look at the quick setup guide for the repeater receiver see index The next connection that needs to be made is the remote base link receiver port 2 audio This is fairly simple If you are using a regular radio such as a mobile rig as a remote base first you should use a resistor that has an equivalent resistance with a sufficient power rating as the radio s speaker as this is the output impedance the radio s speaker output was designed for This resistor shou
