It can be supplied in 1kW and 500 W versions. The transmitter comes as a complete package with an exciter, power supply, power amplifier, interconnecting cables and all required rack mount hardware. The 4075 linear amplifier is designed and engineered for modern communi-
cations which are heavily data orientated, requiring the equipment to work at high duty cycles for extended periods of time. The unique liquid cooled design increases cooling efficiency resulting in less system deterioration due to over-
heating in the power stages, extending overall equipment service life. The compact rack mounted amplifier, together with its power supply occupies just 5U of cabinet space. The Barrett 4075 amplifier natively supports the Barrett 4050 Transceiver/
Exciter which when coupled requires no further tuning or adjustment. A flex-
ible I/O interface and analogue ALC feedback provide the transceiver/exciter full control over final output power. Intelligent electronic controls protect the 4075 from input and output overload while providing a sophisticated early warning and a diagnostic interface for system monitoring and event logging. The 4075 system is field re-programmable via USB allowing the end user to update system software. The Barrett ISO9001 Quality Assurance Program ensures consistent perfor-
mance and the highest reliability. 9 Terms and Abbreviations Term Definition Continuous Wave (used for Morse code) Decibels Decibels relative to the carrier - is the power ratio of a signal to a carrier signal, expressed in decibels.

Power button Micro USB programming interface ATU Interface Box - Optional 1 15 Reference Description ATU Power Switch On/Off An ATU Interface Unit (BCA407536) is required for the 1kW ATU to operate. This ATU Interface Unit provides DC power to the 1kW ATU and also provides a control path from the 4075 Linear Amplifier to the 1kW ATU for tune con-
trol. For further information on the ATU Interface box, please see the 4075 1kW ATU manual (BCM407508). 16 INSTALLATION 2 The new 4075 system is shipped with the Linear Amplifier removed from the rack. All other units are fitted and factory adjusted for optimum operation. All vacant slots are covered. Requirements Housing The ideal housing for the 4075 system is a dedicated radio site in an air-condi-
tioned, secure room connected to mains power. Ideally this room will have its own back-up power source such as solar panels, wind turbines and stand-by batteries. To avoid water ingress and subsequent damage to the system, the racking system should be mounted atop a wooden plinth approximately 4in high. Any vents should not be situated directly near the system to limit condensation reaching the equipment. Cable Management The management of cables will ideally use cable trays to minimise the risk of damage and reduce maintenance. Take care to note the bend radius of the cables. Over-bending a cable can result in shorting. Ideally, power and data cables should be kept separately and cables should not cross, except at 90o where absolutely necessary. Rack Ensure that the rack is positioned with enough space for the front and rear of the system to be accessed safely. Local fire safety guidelines should be adhered to. Connection to Mains Once the rack is located in its final position and secured to the floor, unwrap the internally fitted mains cable and feed it out of the cabinet either at the bottom or through the top cable access point and connect to a suitable mains source. The 4075 high power transmitter systems are usually built into either the 20RU or 39RU racks. Each system includes an AC power distribution box BCA407520. Connection of mains power into this box is via a six metre long 17 mains cable which is directly terminated into the AC power distribution box. The other end of this cable is left unterminated for hard wire connection to a customers mains supply through a suitable high current termination. This termination should be performed by a suitably qualified electrician. Barrett Communications recommend that a dedicated RCD is used in this circuit. Please note that the peak current drawn by the 4075 system exceeds normal wall socket ratings and so connection through a wall socket is not safe and should be avoided. According to Australian / New Zealand Standards, the mains cable conductor colour code is as follows:
Conductor colour Designation Brown Blue Green/Yellow Active Neutral Earth 18 4075 HIGH POWER HF TRANSMITTER - INSTALLATION Grounding The ground (earth) system is a key part of the overall system and consequently of the system performance. An inadequate ground system is the primary cause of poor system performance, noise and lightning damage. When an ATU is fitted, the system ground will include a ground counterpoise which is essential for ATU tuning performance. Base Station Grounding The following major aspects should be considered when installing a land based station grounding system:
Rack and equipment ground with respect to the mains supply and personnel safety is paramount. The installation of all electrical equipment should be in accordance with local bylaws, and grounding is a requirement for effective earth leakage protection. Grounding with respect to EMI (Electro Magnetic Interference):
Due to the high RF fields in the proximity of the transmitter rack, shielding of all equipment and cables is important. Each Rack Mounted main item is connected to the rack vertical ground strip via flexible straps. The supplied system rack and cables have been adequately shielded. The ground point for external connection can be found at the rear bottom of the rack. The rack earth connection should be extended, as directly as possible, to a suitable ground, outside of the building, using preferably, a 50 mm copper earth strap. All signal cables should be shielded and grounded at each end. Lightning Protection Lightning protection also requires a good ground connection and should be similarly connected to the building ground. The lightning protection should ideally be located where the coaxial cables enter the building, and coupled to ground as directly as possible. 19 4075 HIGH POWER HF TRANSMITTER - INSTALLATION Linear Amplifier Unless otherwise specified for special project requirements, all cabling with the exception of the coaxial RF output cable, are installed in the rack and so identification and connection is straightforward. Both the 4075 Linear Amplifier and the 4075 Power Supply units have been factory adjusted for optimum performance. CAUTION: Linear Amplifiers weigh between 30kg (500W configu-
ration) and 35kg (1kW configuration). Two people are required to safely lift and install the Linear Amplifier. The rack has two guide rails that will support the Linear Amplifier once installed. Each side of the Linear has a corresponding channel the slide over the guide rails. 1. Slide the Linear Amplifier into position and secure with the screws pro-
vided. 2. Connect cables as per the diagram on the following page. 20 4075 HIGH POWER HF TRANSMITTER - INSTALLATION 4075 High Power HF Transmitter - Rear Connections A c b a 2 6 9 C 5 4 3 1 ACTIVE (BROWN) NEUTRAL (BLUE) EARTH(GREEN YELLOW) B 7 C 8 10 11 13 D E a b c 12 21 4075 HIGH POWER HF TRANSMITTER - INSTALLATION AC Power Distribution Unit (P/N BCA407520) Barrett 4050 HF SDR Transceiver (P/N BC405000) with Fan attachment

All antennas connect to the Linear Amplifier via the coaxial socket on the left of the rear panel. This is clearly labelled to avoid confusion. Please note that a VSWR of < 2:1 is desirable for optimum performance of the Linear Amplifier. We suggest that for high power transmitters, a type RG-213 or better cable is used for all coaxial feeds beyond the Linear Amplifier. For improved coaxial feeder performance over long runs, we suggest the use of a low-loss coaxial cable. Please contact Barrett Communications if further assistance with cable selection is required. The use of a lightning protection module is recom-
mended. Grounding When an unbalanced antenna or an ATU is used, the antenna ground, or counterpoise is vitally important. Providing an adequate counterpoise at ground level is difficult, but it is far more difficult when the ATU is placed on a roof top. At ground level, the use of 8 to 12 radial wires of 16 gauge or larger, each of about 1/3 longer than the length of the antenna, buried to about 150 mm below the surface should be adequate (Radial earth mat / ground plane:
Barrett P/N BCA20026). Connection to metal water pipes can also improve the ground. On a roof top, there is usually not enough space for an adequate counterpoise. An effective counterpoise may be achieved by covering the entire roof surface below the antenna with wire mesh which is then con-
nected to the ground as directly as possible. It must be noted however, that the successful tuning of the ATU and the resulting VSWR performance of the antenna, will greatly depend on the effectiveness of the counterpoise pro-
vided. 26 4075 HIGH POWER HF TRANSMITTER - INSTALLATION OPERATION 3 Switching On 1. Once connected to Mains power turn the circuit breakers (if fitted) on the rear of the AC power distribution unit (PDU) to the on position. 2. Turn the mains switch on the front of the PDU panel to the on position if using a type 1 or 2 PDU. Ensure the other front switches are set to the on position as required if using a type 2 PDU. If the 4022 Power Supply, 4050 HF SDR Transceiver and the 4075 Linear Ampli-
fier do not also switch on, follow the steps below:

Applicant: Barrett Communications Pty Ltd FCC ID: OW4-407510 7th November 2023 Authorization & Evaluation Division Federal Communications Commission Laboratory 7435 Oakland Mills Road Columbia, MD 21046 Subject: Extended Frequencies Justification for Certification of Transmitter with FCC ID: OW4-407510. Dear Sir/Madam:
This transmitter is designed to operate in the frequency ranges as described in the Exhibit 13a. Barrett Communications Pty Ltd also requests that the FCC certify this product for the entire 1.5MHz to 30MHz band to meet the requirements of users authorized to operate between 1.5MHz and 2.0MHz as allowed by Title 47 CFR 2.106. This would be done to facilitate the requirements of agencies covered under NTIA spectrum usage. Government agencies complying with the NTIA instead of the FCC must purchase their equipment from private industry manufacturers who are governed under FCC rules. The conflict in spectrum allocation detracts from the options available to the government agencies for commercial off the shelf equipment which meets their required specifications such as the Department of Interiors. Please see frequency lists below. The following table lists the CFR 47 Part 87 frequencies for a MF/HF Fixed station transceiver:
