TESTING THE CONTROLLER-TO-REPEATER TRANSMITTER INTERFACE
Apply power to both the controller and the repeater while monitoring the repeater with an extra
receiver. When power is applied, the transmitter should key and send the reset CW message. If
the transmitter does not key at all, check the wiring. Both the controller and the repeater should be
powered up. Check the connection between the controller's PTT output and the transmitter's PTT
input. If the transmitter keying is acting "upside down" (unkeying during the message but keying
afterwards), reverse the repeater transmitter PTT dipswitch.
If the transmitter is keying properly but no CW message is heard, check the wiring from the
controller's Repeater Transmitter Audio Output to the transmitter's audio input. If the CW message
is too loud or too soft, adjust the CW pot on the Main Board (see
Messages
section in this manual).
Turn the pot clockwise to increase the level, and counter-clockwise to decrease the level.
If the CW message is still too loud with the pot turned nearly all the way down, you may be
attempting to drive the microphone input of the transmitter instead of a later stage. If you cannot
drive a later stage, then check the Transmitter Audio Output description in the installation section of
this manual for information on decreasing the transmitter drive level.
