Page 2: Safety Warning
SAFETY WARNING Very high RF voltages, as well as large RF current flow, may be present in your MERCURY ATS. Like all antenna tuners meant for high power use, the MERCURY ATS handles a great deal of RF energy. Your MERCURY ATS 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 MERCURY ATS 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
Radio control interface (Optional) - 3.5 mm audio jack type to specific connector of transceiver to enable transceiver “tune” button. See page 7. Coax Jumper Cables - A Coax jumper of 2 feet or less from the amplifier to MERCURY ATS is recommended. -
Page 5: Main Screen
2 Reflected Power Indicator - Never operate ATS at more than 125 watts of reflected power. 3 Antenna Output Selectors - Select the button for antenna 1, 2, or 3. Antenna 1 will be connected if Mercury ATS is disconnected from 12 volts. The previous selection will remain in memory for the next power-up. -
Page 6: Setup Screen
Setup Screen 1. Beep - Disable the sound of buttons and confirmations. 2. Call Sign - Enter your Cal Sign to display on the main screen, up to 8 characters. 3. Auto - Enable and disable the Auto Tuner option. When SWR is above 1.8 the ATS will start the tuning process when RF is detected. -

Rear View 1. SO239 Input Connector. Connects the signal coming from the transceiver or amplifier. Do not connect Ferrite Clamp or RF Choke on this line. A Coax jumper of 2 feet or less from the amplifier to AT is recommended. 2.SO239 Output Connectors. -
Page 8: Tuning Guide
One of the following Banners will appear on the screen: The MERCURY ATS will calculate the loss and indicate if the tuning is appropriate to handle high power. -
Page 9: Radio Interface Configuration
RADIO INTERFACE CONFIGURATION The control connection from MERCURY ATS to your transceiver allows for an automatic tuning process when the TUNE button on the tuner or transceiver is pressed. The ATS 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 10 IC-7000. IC-7600. IC-7300. IC-7610.

There is no need to change settings after or before tuning.
