OPTIONAL INSTALLATIONS SETTINGS 10 AT 180 internal switch description The optional AT 180 has 3 operating conditions for HF band operation Select a suitable condition according to your antenna system Remove the top cover of the AT 180 Set the tuner switches to the desired positions according to the table below ____________ Operation____________ The tuner operating condition is set by S2 A default described below THROUGH INHIBIT The tuner tunes the antenna even when the antenna has poor SWR up to VSWR 3 1 after tuning In this case manual tun ing is necessary each time you change the frequency although the tuner automatically starts tuning when the VSWR is higher than 3 1 This setting is called through inhibit however the tuner is set to through if the VSWR is higher than 3 1 after tuning CM œ TUNER SENSITIVE CONDITION The tuner tunes each time you transmit r except SSB mode Therefore the lowest SWR is obtained at any given time For SSB mode the same condition as the D position NORMAL CONDITION D The tuner tunes when the SWR is higher default than 1 5 1 Therefore the tuner activates only when tuning is necessary Specifications for the AT 180 Frequency coverage Input impedance Maximum input power Minimum tuning power Matching impedance range Tuning accuracy Insertion loss Connector information for ACC 2 socket 1 9 54 MHz 50 Q 120 W 8W 16 7 150 Q HF band 20 125 Q 50 MHz band PIN NO NAME Less than SWR 1 5 1 Less than 1 0 dB 8V Regulated 8 V output 10 mA max after tuning GND Connects to ground SEND Input output pm Goes to ground when transmitting 20 mA max When grounded transmits BAND Band voltage output Varies with amateur band 0 to 8 0 V ALC ALC output voltage 4 to 0 V NC No connection 13 8V 13 8 V output when power is ON 1 A max Power supply 13 8 V DC 1 A supplied from the transceiver s ACC socket requirements Dimensions mm in 167 W x 58 6 H x 225 D 69 i6 W x25 i7 H x 87a D Weight 2 4 kg 5 lb 4 oz Supplied accessories coaxial cable 1 m ACC cable DIN 13 pins DESCRIPTION 62
