The Linker IIa will always increment the remote base memory up, even when returning to the home memory or to
go to one memory below the current memory. The Linker IIa will “wrap around” memories. When the radio’s
highest memory is reached the Linker IIa will expect the next UP signal to bring the radio to the first or lowest
memory. While the memories are changing (or while any function is active) TX 1 will remain on. When TX 1
drops you will know the memory changing has been completed. The Linker IIa will send a cover tone while the
remote base memories are being selected.
Once all the connections are made and the COS input voltages (you probably don’t need to change these) are set you
will need to program the remote base radio itself. Once this is done the Linker IIa will need to know how many
memories it will have to increment through. This means the actual number of memories that show up on the display
of the remote base radio, even if they are not used. This is done using the “SET NUMBER OF REMOTE BASE
MEMORIES “ function (Function #71). The Linker IIa’s remote base memory numbers start at 0 so the first
memory is always memory number 0 (Home memory). Some radios start at memory 0 and some start at memory 1.
The number the Linker IIa needs programmed in for the number of memories it will have to increment through.
TX 2 will go off if any DTMF tones are recognized on any receiver input. When doing control functions in most
cases it is desirable to not be transmitting on the remote base’s transmitter as the remote base may be on a repeater’s
input or frequency that is being used by others.
