Example 3:
So if you select and tune antenna output B:
Press the jumper in de right position and antenna output A will be floating. (not connected to anything)
Example 4:
So if you select and tune antenna output B:
Connect the jumper in the left position and antenna out A will be grounded
Example 2 & 4 are very handy if you like to use a ladder (open feedline) line like 450 ohm.
STANDARD CONTROL BOX WIRES
LONG RED & BLACK => 12VDC TO TRANSCEIVER POWER SUPPLY
SHORT BROWN => +12V TO COUPLER (PIN 1)
SHORT GREY => START TO COUPLER (PIN 2)
SHORT YELLOW => KEY TO COUPLER (PIN 3)
SHORT BLACK => ANTENNA CHANGE AND MEMORY CONTROL TO COUPLER (PIN 4)
D: TUNING PROCEDURE USING THE STANDARD CONTROL BOX
- We set the jumper switch of the control box to antenna "Α" or "Β".
-
We set the transceiver in AM, FM, RTTY or CW mode and we adjust the output carrier power
somewhere in between 10 and 20 watts.
-
We push the button on the control box until the red LED is lit
- We activate PTT keeping the transceiver transmitting some power.
- We wait until the LED goes off and then we stop transmitting. During this process you can hear
all relays fast clicking if you are nearby the coupler.
If the LED goes off the “tune process” is finished. (The SWR must be 1:1) If you push the tune button of
the control box and if you do NOT activate your transmitter the led will go off after a few seconds. (time
out) If the LED quickly turns on and off at the end of the tuning procedure, the tuning procedure has
failed!
E: MEMORY OPERATION
As soon as the coupler is supplied with 12V with the antenna change switch not in the middle (antenna
“A” or “B”), it is found tuned to the previously used frequency. If the switch was in the middle, the
coupler starts up in the “through” position. To operate the coupler without memories, the moment we
apply 12V to the coupler the antenna change switch must be in the middle position (the antenna change
line must be floating!) Afterwards, we can select the desired antenna, "Α" or "Β".
NOTE : The coupler does not memorize tunings with SWR > 1.3 : 1

To erase the memories from antenna “Α”, we must apply 12V to the coupler with the START
button pushed and the antenna change switch in antenna "Α". With the antenna change switch
in antenna "Β" we erase the memories from antenna "Β".
