Page 5: Introduction
Kenwood serial data. With proper interface cables and data, this amplifier will automatically change bands in step with transceiver band changes. Automatic band selection using a band data port or band decoded bus requires purchasing an Ameritron interface cable for your radio. -
Page 6: Amplifier Features
Amplifier Features This amplifier provides the following standard features: 160 through 6-meter operation, full-power on six meters. Four conservative linear-service rated 50-volt MOSFET transistors. New push-pull stripline PA layout with exceptional VHF performance. Energy-efficient solid-state design greatly reduces heat, <100-watts power line draw on receive. -
Page 7: Quick Start
This includes operation on various line voltages, power supply operation, fuse selection, location, and power supply trouble shooting. Non-export versions of Ameritron ALS-600 series power supplies are wired and fused for 120Vac USA power mains, but all are modifiable to other standard power mains voltages. -

mains supply, you may have to use a dedicated 120-V amplifier line, or rewire the supply and use 240-volt mains. With 120Vac mains at 600-watt nominal RF output, current draw is approximately 12 amperes on steady carrier. Peak line current is typically much less than 8 amperes at 600 watts PEP on SSB voice. -
Page 9: Radio And Antenna Connections
Unless you have a very unusual radio, your radio should directly key this amplifier. Avoid using external interfaces with relays. Amplifier relay switching time is approximately 10-12 mS. The remote and radio band data connectors are specialized connections. They are for use with Ameritron supplied cables only. Version 0A... -
Page 10: Operation
Operation Before attempting operation: This amplifier is optimized for 50-ohm loads. Be sure your antenna system 50-ohm SWR is as low as possible. As SWR increases from 1:1, either heat or distortion will increase. Be sure your antenna system, including any switches, baluns, matching circuits, or lighting protection devices, are in good condition and will safely handle high power. -

Page 14: Power Line Requirements
1250 watts average power and 1500 watts peak dc power. The 12-volt supplies are for illumination, bias, and control functions. Power supply to amplifier interconnections are through a heavy-duty cable using reliable Cinch Jones connectors. Power Line Requirements This amplifier ships wired for a nominal mains voltage of 120 Vac with either supply. Maximum power line current at full power output is 12 amperes at 120 volts. -
Page 15: Amplifier Overview
Amplifier Overview The Ameritron ALS-606 is a solid-state, 600-watt nominal RF output power, 1.8-54 MHz amplifier. The ALS-606 meets or exceeds all FCC requirements governing amateur radio external power amplifiers. The ALS-606 uses four low-distortion MRF-150 (or equivalent) SSB RF power transistors in push-pull parallel. -
Page 16: Installation
Installation Please look your amplifier and power supply over carefully. Observe the air inlet and outlet ventilation holes. Facing the amplifier front panel, the cooling air inlets are on the top left and lower right side, including the right hand side cabinet bottom. Warm air exits vents at the cabinet rear. -
Page 17: Station Ground
15P 15-ampere 120-volt plugs. The round center pin is the safety ground. Do not remove the safety ground. CAUTION! Before connecting the power supply to an electrical outlet, always be sure you have completed the following four steps: 1. Insert the 15-ampere 250V fuses into the two black fuse caps. 2. -
Page 18: Safety And Lighting Grounding
Safety and Lighting Grounding The power supply cabinet grounds through a safety ground pin on the power plug. This system depends on a properly wired power outlet. Lightning protection grounds do very little good at the operating desk. Lightning protection grounds belong at the antenna cable entrance to the building. Station ground rods must always electrically connect through low impedance and resistance conductors to the power line entrance ground. -
Page 19: Operating Frequency Range
This amplifier has significantly cleaner output purity than FCC part 97.307 requirements (January 2016) when operated inside all amateur bands listed in the table above. Ameritron does not guarantee harmonic suppression or operation in applications outside standard amateur radio bands. -
Page 20: Warning Lights
Most non-amateur services prohibit use of non-commercial radio equipment. This amplifier automatically prevents operation between 25 and 28 MHz. Operation in the 25- 28 MHz range is not available with this product, irrespective of licensing or end-use. Warning Lights The ALS-606 has two primary warning lights in the center of the front panel, SWR and PA. -

amplitude carriers like a steady CW carrier, when PEP and average powers are equal. PEP is the highest average power during one (or more) radio frequency cycle(s) at the modulation envelope crest. The meter’s rightmost scale-arc indicates PEP reflected power in watts on the upper scale numbers and pickets. - Page 24 50-ohm coaxial cable and system beyond this connector must safely handle at least 600-watts. RADIO INTERFACE This connector is for use with Ameritron radio interface cables. It allows automatic band selection (following the radio). It also provides amplifier actuation in transmit mode with some radios.

600-watt rated Power/SWR meter, antenna, or antenna matching device. Good quality Mini-8 or RG-8X cables are acceptable for anything but RTTY use, although larger RG-8 style cables are normally preferred. The antenna matching system, or antenna tuner, must connect to this port. Connect the RF IN connector to your transceiver. -

threshold. This overshoot, dip, and recovery is caused by slow radio ALC response time. Excessive ALC control loop gain aggravates power bounce. ALC attack bounce shows on a steady carrier (such as RTTY, CW, or FM) as a high initial peak power reading followed by a deep null. The deep null is followed by a slow settling to the desired power level. -
Page 28: Als-600Sps Voltage Settings
ALS-600SPS Voltage Settings When opening up the ALS-600SPS make sure it is unplugged and has been off for a while to make sure the capacitors have been discharged. Some of the capacitors can have a charge of 300-400VDC. The ALS-600SPS will only need to be changed when switching between 120 and 240VAC. -

panel RELAY control line is held low (below 1 volt), exciter power is routed through input relay RLY1 to the PD8m power attenuator board. ATTENUATOR BOARD The attenuator board has two 3dB attenuators. A relay switches one attenuator out on six meters. -
Page 30: 1Kwf6 Low Pass Filter Assembly
1KWF6 Low Pass Filter Assembly The PAM-606 module connects directly to the 1KWF6 circuit board assembly through a 50-ohm cable. Power enters the filter system through a directional coupler consisting of current transformer T2, capacitors C36-38, C40-42, and resistors R4, 5 and 6. This directional coupler detects termination errors at the filter’s power amplifier side. -
Page 31: Cb2
The CB2 is located on the amplifier side between the band selector and power jack, below the attenuator board. The CB2 control board provides most control functions, including bias, fan speed, overload, wrong-band protection, and transmit-receive relay sequencing. It is the hub for nearly all functions, including external interfaces, power metering, and 12-volt busses. -
