Page 2: Safety Warning
SAFETY WARNING Very high RF voltages, as well as large RF current flow, may be present in your mercuryAT. Like all antenna tuners meant for high power use, the mercuryAT handles a great deal of RF energy. Your mercuryAT is designed to safely handle this RF energy within its specifications, with a reasonable margin of safety. -
Page 3: Good Practice
GOOD PRACTICE Be sure to observe the mercuryAT specified power ranges. If the tuner fails due to overload, it could also damage your Transmitter or Amplifier. An antenna tuner transforms the impedance at the power point from the line to the equipment, to a value suitable for the transmitter, typically 50 Ohms. -
Page 4: Connections Diagram
Power Cable: Connect the power cable to an external power supply up to 13.8VDC. Use Red for (+) and black for (-). Never power up your mercuryAT through the transceiver. Use the same power source with which the transceiver is powered since mercuryAT does not have a power switch. -
Page 5: Main Screen
Tune Button - Press the TUNE Button to tune, the banner (TUNE CALL) will be displayed and mercuryAT will be ready to receive a continuous 10-watts carrier to start the auto adjustment. SLEEP Button - mercuryAT will turn off the Display. The Antenna Relays and LC adjustment will remain energized, however. -
Page 6: Rear View
Do not block rear area and please leave either the left or right side of mercuryAT clear for proper airflow. DC Power Connector - Connect the power cable to an external power supply up to 13.8VDC. -
Page 7: Tuning Guide
PTT Disconnect cable is installed, this is not necessary. Make sure that the Bypass Button on the mercuryAT is turned off and press the TUNE Button for 2 seconds. You will see the Banner read “Tune CALL” on the screen. -
Page 8: Radio Interface Configuration
The control connection from mercuryAT to your transceiver allows for an automatic tuning process when the TUNE button on the tuner or transceiver is pressed. The mercuryAT sends a PTT signal (Active Low) into a tuner-dedicated port on the transceiver and the transceiver begins transmitting a low-level CW tone. - Page 9 ICOM IC-7000. IC-7600. IC-7300.
