For a description and a diagram of accessory equipment included with the IC-7600, see ‘Supplied accessories’ on p. ?? of this manual. For radio communications, the antenna is of critical importance, along with output power and receiver sensitivity. Select antenna(s), such as a well-matched 50 ø antenna, and feedline. We recommend 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) on your operating bands. The transmission line should be a coaxial cable. When using a single antenna, use the [ANT1] connector. N Selecting a location Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electromagnetic sources. The base of the transceiver has adjustable feet for desktop use. Set the feet to one of two angles depending on your operating preference. CAUTION: Protect your transceiver from lightning by using a lightning arrestor. PL-259 CONNECTOR INSTALLATION EXAMPLE 30 mm Coupling ring To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND terminal on the rear panel. For best results, connect a heavy gauge wire or strap to a long ground rod. Make the distance between the [GND] terminal and ground as short as possible. R WARNING: NEVER connect the [GND] terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock. [GND] Slide the coupling ring down. Strip the cable jacket and soft solder. 10 mm (soft solder) 10 mm Soft solder 1–2 mm N Grounding Strip the cable as shown at left. Soft solder the center conductor. solder solder Slide the connector body on and solder it. Screw the coupling ring onto the connector body. 30 mm (9⁄8 in) 10 mm (3⁄8 in) 1–2 mm (1⁄16 in) 10 11 12 Antenna SWR Each antenna is tuned for a specified frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0:1, the transceiver’s power drops to protect the final transistors. In this case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting. The IC-7600 has an SWR meter to monitor the antenna SWR continuously. 13 14 15 16 17 18 19 20 21 16 2 INSTALLATION AND CONNECTIONS N Required connections D Front panel TIMER CW KEY TX RX SPLIT LOCK SPLIT HF/50MHz TRANSCEIVER POWER TRANSMIT DUAL WATCH TUNER MONITOR BAL PHONES NR CHANGE 1.8 3.5 10 14 18 24 28 50 F-INP ENT 21 GENE MP-W MP-R MW VFO/MEMO TWIN-PBT PBT-CLR MAIN /SUB M.SCOPE NOTCH NOTCH APF/TPF CW PITCH ELEC-KEY XFC NB AF TS NR RF/SQL RIT MIC GAIN A straight key can be used when the internal electronic keyer is turned OFF in keyer set mode.
