Connection to Antenna & Power Supply The 418 is designed for use with any antenna system providing 50 Ohm resistive impedance at the desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is as close as possible to the specified 50-Ohm value. Note: that the “G5RV” type antenna and some Windom’s do not provide 50-Ohm impedance on all HF Amateur bands, and an external wide-range antenna coupler may be needed with this type antenna. Any antenna to be used with the 418 must, ultimately, be fed with 50 Ohm coaxial cable. The 418 requires a source of well-filtered and regulated DC voltage. The supply voltage on the 418 is 13.8 Vdc nominal +/- 15% to allow for mobile and battery operation. The voltage source must be capable of supplying 23 amperes continuous duty. The model 940 or 941 TEN-TEC power supplies will meet or exceed your voltage and current requirements. We recommend using the included DC power cable (P/N 46214). Use of #12 stranded wire is recommended for mobile and in home use to accommodate the required current demand during transmit. Note: Always enable the power source first and then the amplifier. If a generator or battery connected to a charger is used to supply the DC source, always turn off the amplifier before starting or shutting off the DC source equipment. These recharging devices often generate large voltage spikes that can damage the amplifier. 1.5. A word about grounding A good ground system is essential for optimum operation …

Theory of Operation With the Model 418, Ten-Tec has created a 100-watt solid state silicon MOSFET amplifier combining automatic and manual control for ease of operation in the 160 through 6 meter ham band. Refer to the Block Diagram for the following discussion. Receive signals are routed through the antenna connector to the antenna relays on to the T/R relay switching on the Lowpass Filter Board. From here the receive signals are passed on to the Radio connector. Transmit signals are applied at the Radio connector and routed to the T/R relay switching on the Lowpass Filter Board and then on to the input attenuator, input power bridge and frequency counter. The transmit signal is then applied to the 100-watt MOSFET amplifier and passed back to a lowpass filter to be applied to the correct filter and then on to the antenna relays, and finally, to the antenna connector. The PIC processor in the CPU module executes the firmware to perform certain functions. Those functions include: 1. checking input power and frequency 2. enabling bias to the MOSFET amplifier 3. checking SWR 4. checking current 5. checking output power 6. checking temperature The PIC performs these functions based on input from the front panel buttons, key in jack or data from the ACC 1 connector. Cooling is achieved with the two internal fans that are also controlled by the CPU.

Connection to Antenna & Power Supply The 418 is designed for use with any antenna system providing 50 Ohm resistive impedance at the desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is as close as possible to the specified 50-Ohm value. The 418 requires a source of well-filtered and regulated DC voltage. The supply voltage on the 418 is 13.8 Vdc nominal +/- 15% to allow for mobile and battery operation. The voltage source must be capable of supplying 23 amperes continuous duty. We recommend using the included DC power cable (P/N 46214). Use of #12 stranded wire is recommended for mobile and in home use to accommodate the required current demand during transmit. Note: Always enable the power source first and then the amplifier. If a generator or battery connected to a charger is used to supply the DC source, always turn off the amplifier before starting or shutting off the DC source equipment. These recharging devices often generate large voltage spikes that can damage the amplifier. A word about grounding A good ground system is essential for optimum operation of any HF transmitter. The best solution is to connect all the station equipment to a single ground connection. Refer to Local and National Electrical Codes before making any connections with the 418. Another source of information on grounding can be found in the ARRL Handbook. A good ground system can contribute to the station efficiency in a number of ways including minimizing the possibility of electrical shock, and minimizing RF currents flowing on the shield of the coax cable causing interference to electrical equipment and transceiver accessories. It is critical that the power supply, the 418, and other equipment in the station be properly grounded to an Earth ground. Improper grounding can lead to various issues, including RFI, ground loops, or even death. Therefore it is extremely important to refer to the Local and National Electrical Codes and ARRL Handbook with regards to grounding. Amplifier Hookup 418 to 539 The 418 can be interfaced to the 539 using only the 8 pin din cable. The 539 will control band changes and keying the amplifiler 418 to other The 1/8” key jack provides a key input on the tip and a key output on the ring to allow the 418 to key other transceiver. Some methods are shown below. Cable number 46216

The Ten-Tec Model 418 has met these requirements, and the results are documented in this report. The tests were performed according to the measurement procedures also shown in this report. We attest that the Part 2 and Part 97 tests were completed at: Ten-Tec, Inc. 1185 Dolly Parton Parkway Sevierville, TN 37862 Boyd Lichlyter Lee Jones Mike Webber The Part 15 tests were completed at Global Testing Labs. This data is in a separate report appended to the end of this report and contains its own attestations. 4 OTHER INFORMATION The amplifier operates only in the amateur radio bands below 30 MHz and also in the 6 meter amateur band (50-54 MHz). The amplifier is NOT capable of operation on any frequency outside of the amateur bands including 26-28 MHz and also will NOT operate above 54 MHz. The amplifier typically requires 4-6 Watts of drive to obtain full output power depending upon which transmit band it is on. The gain of the amplifier is less than 15dB on all bands under all conditions. In off or standby positions the amplifier does NOT amplify. The exciter energy is simply passed on to the antenna at the same level in which it entered the amplifier. The spurious emissions of the transceiver remain unaffected. PART 2.815 (b) (1) (2) The Ten-Tec Model 418 external RF amplifier is not capable of amplification in the frequency band 26-28 MHz and cannot be modified to operate in the 26-28 MHz frequency band. Any attempt to drive the amplifier in the 26-28 MHz frequency band will result in 0 dB gain from input to output of the amplifier. PART 97.313 The output power will not exceed 115 Watts into 50 Ohm resistive load. Therefore, it is impossible for the output power to reach or exceed the 1500 Watts PEP legal limit. PART 2.1033 (c) (8) Input Power: DC Voltage (13.75 Volts) x DC Current (16 Amps) = 220 Watts 5 TEST SETUP AND CONDITIONS The data collected to verify conformity with Part 2.1046 (a), Part 2.1053, Part 97.307 (d) (e) and Part 97.317 were taken at Ten-Tec, Inc located at 1185 Dolly Parton Parkway, Sevierville, TN 37862. The temperature was 23°C. EQUIPMENT LIST Ten-Tec Model 599 (Exciter) Bird Thruline Model 43 (Wattmeter) Bird Termaline (50 Ohm Load) Anritsu MS2601B (Spectrum Analyzer) TEST PROCEDURES The test procedures used to perform measurements on the Model 418 were taken from the following sections of CFR Title 47: Telecommunication. Part 2.1033 (b) (6) Part 15.31 (a) (3) [see also] Note to paragraph (a) (3) Part 97 The details of the test setup for each test are described in the sections that follow. 6 RF POWER OUTPUT The setup to measure the RF power output was made by connecting the output of a Ten- Tec Model 599 transceiver (the exciter) to the input of the Ten-Tec Model 418 amplifier. A watt-meter was placed in-line between the amplifier and a 50 ohm load. The exciter was tuned to a frequency in the center of each band shown. The amplifier was powered with the voltage and current previously indicated. The input and output power was recorded, and the gain was calculated. The gain does not exceed 15dB and the output power is under 1.5kW PEP into a 50 ohm load.

A 50 ohm load was connected to the amplifier, and a spectrum analyzer was connected to the 50 ohm load. The exciter was tuned to the frequency shown and each harmonic of that frequency up to the tenth was observed on the spectrum analyzer.
