SPECIAL FEATURES OF THE ICS LINKER IIa
CTCSS Encode / Decode Control
A very powerful feature of the Linker IIa is the support for the CSI TS-64 CTCSS encode / decode board for port 1.
Although this feature was designed with the CSI TS-64 board in mind it will work with many others as well. This
feature includes a separate plug to support the CSI TS-64 CTCSS board, CTCSS decode enable, CTCSS encode and
an encode hang timer for port 1. The CTCSS encode signal is mixed in with the repeater transmit audio. For more
information on this feature see the section on the CTCSS encode / decode control.
The Linker IIa gives you the option of having receiver 1 or receiver 2 (or both) enable transmitter 1 encode. The
Linker IIa has commands to enable and disable these functions. The commands are Enable RX 1 CTCSS encode
activate (function #110), Disable RX 1 CTCSS encode activate (function #111), Enable RX 1 CTCSS encode
activate (function #112), Disable RX 2 CTCSS encode activate (function #113).
Port 2 modes
Some other features special that the Linker IIa has are xpeat mode, slave repeater mode and full duplex mode on the
2ad port (Link / Remote base port). The xpeat is designed to activate transmitter 1 when receiver 2 becomes active
and transmitter 2 when receiver 1 is active. Receiver 1 will have priority.
The slave repeater mode on the ICS Linker IIa will allow two repeaters to be run on one controller. As the Linker
IIa has one IDer both repeaters will be IDed at the same time. The IDer will still try not to ID over any conversation
on either repeater.
The full duplex mode on the ICS Linker IIa allows full duplex operation on port 2. Both receivers and both
transmitters can be on at the same time and the audio from both receivers will be mixed together.
The Linker IIa now has a function to report what the remote base radio is set to (function #129). The controller will
report in morse code what memory the remote base is set to.
Beacon Mode
The Linker IIa now has Beacon mode. When the Linker IIa is in Beacon mode it will send the ID when the IDer
pending ID timer times out (see function #68). The polite ID timer will still operate holding off the ID until the
polite ID timer times out or until the receiver becomes nonactive.
Programmable Tones
Another new feature for the Linker IIa is programmable tones. There are currently 5 programmable tones
And 40 different tones available to put in the programmable tones. There are two new additional programmable
tones. The new tones are port 1 programmable tone when port 2 is active and change memory programmable tone.
Antikerchunker Filter
The Linker IIa's antikerchunker filter will help eliminate the kerchunking of your repeater. The operation is simple,
when the antikerchunker filter is enabled (see the Enable antikerchunker filter (command #118) and the Disable
antikerchunker filter (command #119) ) and Linker IIa sees that the repeater receiver is active the Linker IIa will
wait a programmed period of time (see the Set antikerchunker filter delay (command #120)) before it recognizes the
repeater receiver as active. If the repeater receiver stays active for the preprogrammed period of time the Linker IIa
will then recognize the repeater receiver as being active. Once the Linker IIa recognizes the repeater receiver is
active the Linker IIa will temporarily disable the antikerchunker filter for a preprogrammed period of time (see the
Set antikerchunker filter interval time (command #121).
