Linear Amplifier Interconnections

• VL-1000 Linear Amplifier Interconnections

Be sure that both the FTDX101D and VL-1000 are turned OFF, and then follow the installation recommenda-
tions contained in the bellow illustration.
• Refer to the VL-1000 Operating Manual for details regarding amplifier operation.
• Do not attempt to connect or disconnect coaxial cables when your hands are wet.

• Interfacing to Other Linear Amplifiers

• The TX GND OUT pin (pin 2) of the LINEAR jack is a transistor "open collector" circuit. It is capable of
handling positive relay coil voltages up to +60VDC at 200 mA or +30 VDC at 1 A.
• When using multiple linear amplifiers for different bands, you must provide external band switching of the
"Linear Tx" relay control line from the "TX GND OUT" line at the LINEAR jack.
Do not exceed the maximum voltage or current ratings for the "TX GND OUT" pin (pin 2) of the LINEAR jack.
This line is not compatible with negative DC voltages, or AC voltages of any magnitude.
