Exhibit 8: Operational Description External Radio Frequency Power Amplifier ACOM 1010 Model 1010 71 West street Medfield, MA 02052 Tel: 508 359 5990 fax: 508 359 5989 E-mail: [email protected] Exhibit 8 page 2 of 3 Operational Description The ACOM1010 is a complete and self-contained linear amplifier that covers the amateur band 1.8-29.7MHz and provides 700W-output power with typically 60W-exciter drive. It is based on and similar to our previous model ACOM1000 (FCC ID: OITA1000) but lower power and without the six meters band. Amplifier’s tuning is simplified by a plate-load True Resistance Indicator (TRI) which helps the operator to quickly and precisely match antennas and eliminates probability of inadvertent mistune. The antenna impedance matching capability is up to VSWR 3:1 or higher. A fixed matching circuit to the tube input is employed which results in a very good load to the exciter over the entire frequency band from 1.8 to 29.7MHz, yielding a good linearity. Look at the schematic diagram (Exhibit 3). The high-performance ceramic-metal tetrode V1, type 4CX800A (GU74B) from SVETLANA, with a plate dissipation of 800W, is grid-driven. The input signal is fed through the fixed input-matching circuit, which comprises several L/C components and a 50 Ohm/100W RF swamping resistor (Rsw) in the INPUT PCB. This circuit tunes out the input capacitance of the tube. The swamping resistor is not an attenuator but it is a termination load for the input matching circuit. It could not be eliminated since a severe impedance mismatch to the driver would prevent using the amplifier at all. The ceramic-composite resistors Rc.1 and Rc.2 create a DC and RF negative feedback in the cathode circuit, thus stabilizing the gain and equalizing the tube specimen performance. The varistor VSsg in the screen grid circuit protects the tube screen grid and the voltage regulator in the events of dynatron effect or a tube internal flashover. The nominal voltages and currents of the tube at rated output power are as follows: DC plate voltage: 2300V for SSB and 2000V for RTTY; DC plate current: 0.48A for SSB and 0.42A for RTTY; DC screen voltage: 265V; DC screen current: 30mA; DC grid bias: -48V (adjusted individually for idling plate current). The combination of Lp1/Rp1 in the plate circuit suppresses possible VHF/UHF parasitic generation. The output resonant circuit comprises the tube output capacitance, Lp1, CP1, CP2, CP3, LP1, LP2, CL1, CL2, CL3, CL4, and LL, all connected in a double-Pi-L network. It transforms the antenna impedance to the tube-optimum load impedance, and besides suppresses the harmonic frequency emissions. The tank is tuned over the bands and the impedance matching is controlled by the ceramic-supported air variable capacitors CP1, CP2, CL1, and CL2. The DC plate voltage is fed through the plate-choke RFC1 to the anode, in a parallel circuit with the tank. The series capacitors Cb3.1 and Cb3.2 prevent the DC voltage from reaching the resonant tank and/or amplifier’s output, while the low-pass filter Cb1.1/Cb1.2/RFC2/Cb2 prevents the RF voltage from reaching the DC power source. The output signal is fed through a piece of coaxial cable, to the “RF OUTPUT” connector through the wattmeter. A high-pass filter at the output (integrated with the wattmeter) eliminates the influence of eventual close-sited powerful LF/MF transmitters as well as 50/60Hz power lines on the amplifier. Also, it prevents DC high voltage from reaching the antenna output, thus improving operator’s safety. The amplifier is controlled by a microprocessor system, based on the ATmega micro- controller from Atmel. It uses a 4MHz clock, stabilized by a piezo-ceramic resonator. An intended constructive capacitance Ca feeds information from the plate RF voltage. Together with the directional RF wattmeter at the output, they are the main information sources for the control circuit to form the TRI aid during the antenna impedance matching process. The relay K1 0n the wattmeter PCB switches the antenna for transmit and receive. The relay K2 on the same PCB selects two different antenna outputs A1 and A2. Exhibit 8 page 3 of 3 All supply voltages are delivered from conventional rectifiers and linear regulators and no switching supplies are used. The currents of the tube control grid, screen grid, and plate, as well as the forward and reflected power, the alternative anode voltage etc are continuously monitored by the uP controller. Many software-derived protections are based on this information in order to insure normal tube regime and antenna tuning, thus drastically reducing the probability of any inadvertent operator’s mistakes or apparatus irregularities that could arise during exploitation of the amplifier.

Exhibit 11 Page 1 of 13 International, Inc. Exhibit 11: Tuning Procedure and Parts List External Radio Frequency Power Amplifier ACOM 1010 Model 1010 71 West street Medfield, MA 02052 Tel: 508 359 5990 fax: 508 359 5989 E-mail: [email protected] Exhibit 11 Page 2 of 13 4-5. Tuning Tuning is possible only in the OPER mode. a) Preliminary information. Tuning the amplifier involves a procedure of matching the impedance of the antenna and transmission line to the amplifier tube’s characteristic load resistance. This will ensure maximum plate efficiency and RF gain at nominal output power, with minimal distortion and spurious output. Note that REFLECTED POWER readings depend on the antenna and transmission line impedances only, and not on amplifier tuning. If the load impedance is not a nominally resistive 50-Ohms, the REFLECTED POWER reading will always show a reading, no matter what the tuning settings. Proper tuning is always necessary, however, and will allow you to operate at a high power level, without distortion or any danger to the amplifier. Note also that the real OUTPUT POWER presented to the load (the antenna and transmission line) is equal to the difference between the FORWARD and REFLECTED power readings. For instance, with a 2.5:1 VSWR, readings of 800 W and 150 W FORWARD POWER and REFLECTED POWER, respectively, the real OUTPUT POWER is 650 W. At very high VSWR levels, such as when no antenna is connected or a badly mismatched antenna is used, the FORWARD and REFLECTED readings will be almost equal, while the real OUTPUT POWER (the difference between them) will be nearly zero. The amplifier can operate safely as long as the REFLECTED POWER is LESS THAN 250 W. Matching is assured for loads presenting a VSWR of up to 3:1. Nevertheless, for some loads and bands, matching is possible at even higher VSWR levels, but the drive power must be reduced to prevent the REFLECTED POWER from exceeding 250W. Failure to comply with these guidelines will cause the protection circuits to trip. For example, if the antenna VSWR were 5:1, the maximum attainable forward power would be 540 W, 240 W of reflected power and real output to the antenna and transmission line of only 300 W. In the event your antenna cannot be adjusted to produce a lower VSWR, an external antenna tuner may be deployed. CAUTION At elevated VSWR levels, high voltages and high currents are distributed along the coaxial cable to the antenna, risking internal arcing and heat generation, and likely damage to the cable and any antenna switches that may be used. It is recommended that VSWR levels of more than 3:1 not be permitted with coaxial cable above 14 MHz. It is advisable to adjust amplifier tuning when antennas have been changed, snow has fallen, new objects are in the near field of the antenna, etc. Such changes may affect antenna impedance. NOTE If you use more than one antenna on a band, the proper antenna must be selected prior to performing the tuning procedure outlined below. CAUTION To avoid damage not covered under warranty, do not switch the BAND switch knob while transmitting. As discussed above, hot switching will damage the amplifier’s band switch! CAUTION Also, never apply drive longer than one minute continuously without pausing for at least one minute to allow the tube to cool. It is recommended that for initial tuning a frequency in the middle of the band be used. First, with no transceiver power applied, select the band. Then use Table 4-1 to achieve an approximate preset for both TUNE and LOAD capacitor knob settings: Exhibit 11 Page 3 of 13 Band LOAD TUNE MHz Knob Dial Knob Dial 1.800 - 2.000 42 - 71 55 - 28 3.500 - 4.000 32 - 57 52 - 31 7.000 - 7.300 29 - 40 36 - 27 10.100 - 10.150 59 - 66 50 - 44 14.000 - 14.350 33 - 39 42 - 30 18.068 - 18.168 17 - 35 60 - 50 21.000 - 21.450 50 - 60 15 - 10 24.890 - 24.990 38 - 42 80 - 72 28.000 - 29.700 51 - 64 41 - 24 Table 4-1. Approximate tuning preset b) Tuning Procedure. (1) Once the antenna and band have been selected (and the TUNE and LOAD adjustments have been initially set as indicated in Table 4-1), apply between 10 and 20 W of continuous (key down CW) signal. (2) Look at the upper LED bar-graph (FORWARD POWER) and adjust the TUNE (right hand) capacitor for maximum indication. (3) Watch the TRI indicator above the LOAD (left hand) capacitor and turn the LOAD capacitor in the indicated direction to center the green LED indicator light. (4) Increase the drive power to get the desired nominal output; then repeat steps (2) and (3), always peaking output with the TUNE adjustment. NOTE No light on the TRI indicator means that the tuning is too far off. To correct this, turn the LOAD and TUNE knobs around the table-suggested positions until the TRI indicator illuminates. no light: tuning is far left: tuning is far right: marker inside: LOAD is tuned: use TUNE knob turn LOAD knob turn LOAD knob turn LOAD knob turn TUNE knob for max. Power to the right to get to the left to get slightly left to peak Forward to get any marker the inside markers inside markers to center it Power Fig. 4-1. Using TRI tuning aid The TRI indicator will not illuminate until at least 20 W of forward power (output) is achieved. In the event successful matching cannot be accomplished, check the BAND switch position and antenna selection. Then check the antenna VSWR at the same drive frequency. d) Tuning hint. A benefit of TRI is that the knob positions are virtually independent. The plate-load resistance decreases to the right and increases to the left of the TRI center. A centered tuning indication corresponds to the proper LOAD capacitor tuning, which presents an optimum load resistance to the tube. If the LOAD knob is turned to the left with a centered TRI, there will be more gain, but less linearity. When available drive power is insufficient or when less output but better efficiency are needed, e.g., for RTTY and SSTV, this may be desirable. Tuning to the right of the center would lead to the op…
