FCC 97.317(b). Section c.6. The equipment can be operated at the maximum power “MAX” state automatically using the ALC link. To reduce the amplifier output, if required, it is necessary only to set the amplifier to “MID” or “LOW” power state rather than changing the transceiver drive power. It is also possible to regulate continuously the amplifier output power by changing the level of drive power from the transceiver. Section c.7. The equipment is rated for maximum RF power output of 1300 W PEP, with a continuous signal is limited to 1000 W. Section c.8. Normal currents and voltages are: “MAX” (1300 W), PA voltage 48 Vdc, 40 Adc. “MID” (950 W), PA voltage 36 Vdc, 34 Adc. “LOW” ( 500 W), PA voltage 32 Vdc, 22 Adc. Section c.9. The amplifier has an automatic tuner that handles load mismatches up to 3:1 VSWR (2.5:1 for 50 MHz). The amplifier contains a look-up table with the amateur bands only (continuous coverage is inhibited, including CB band). For the tuner management, antenna data and other working data are stored. Every band has a sub-band set, and for each of those, data related to the antenna and auto-ATU tuning is stored. The procedure description is included in Exhibit 11, as well as in the User’s Manual – Exhibit 6. Section c.10.

Tel.

Being only 7.5 Kg. (16.5 Ibs), it is perfect for use in the shack and is superior to for DXpeditions. All operating conditions (frequency, antenna, tuner etc.) are controlled from the transceiver. The operator has to only move the frequency-tuning knob, it is extremely user-friendly and offers a product which is the best in its class. The linear amplifier has two inputs (INPUT 1, INPUT 2) to which it is possible to connect two transceivers of any brand or type. These inputs are selected with the [INPUT] key or automatically. It can manage up to four antennas (ANT 1, ANT 2, ANT 3, ANT 4). The amplifier selects antennas automatically when they have been programmed. The amplifier is constituted by a class AB single push-pull performed by a just one dual mosfet device. This simplifies the design and increases the reliability of the amplifier. The modern transceivers have CAT control, thanks to this link the linear amplifier detects the operating frequency of the transceiver and then automatically changes band, antenna and automatic tuner. The power supply of the SPE Expert 1.3K-FA, unique in its category, is switching with a PFC (Power Factor Correction) that allows a drastic reduction of the harmonic components in the mains in accordance with IEC555-2. The power supply meets also the followings rules: UL60950-1, TUV EN60950-1, EN55022, EN61000-3-2,- 3, EN61000-4-2,3,4,5,6,8,11; ENV50204, EN5502. It consists of two separate elements: The first powers all the electronic circuits for command and control. The second powers only the PA, its output voltages are 48 Vdc (MAX Pout), 36 Vdc (MID Pout), and 32 Vdc (LOW Pout). The amplifier has an automatic tuner that handles load mismatches up to 3:1 VSWR (2,5:1 for 50 MHz). A unique feature of this linear is that it not only measures the SWR after the matching, but also the SWR of the system antenna / cable, this allows to always evaluate the antenna system despite the matching and the power applied. The amplifier contains a look-up table with the permitted amateur bands only (continuous coverage is inhibited, including CB band). In the tuner management, antenna data and other working data are stored. Every band has a sub-band set, and for each of those, data related to the antenna and auto-ATU tuning is stored.

(39-6) 58209429 Fax (39-6) 58209647 Website www.linear-amplifier.com e_mail [email protected] Pag. 3 / 3 Exhibit 8 The CAT information and the frequency counter inside the linear detect the operating frequency and set the correct sub-band. Thanks to the stored data, the tuner and the antenna are automatically set correctly. Setting of the match data to write in the tables is performed automatically by pressing the [TUNE] key, the system will then find the correct match for minimum SWR. The internal tuner may be bypassed as follows: - Totally. - For single band. - For single band and specific antenna. It is always automatically bypassed: - With the only receiving antenna set. - With tunable antenna set. The SPE Expert 1.3K-FA has a sophisticated protection system that constantly controls the amplifier’s most important parameters. These main parameters are: Temperature of the heatsink; max. / min. voltage on the PA; max. PA current; SWR; max voltage RF on the tuner; input power. The protection system is effected in two different ways: 1) Through hardware circuits to guarantee minimum intervention time. 2) Through software, with one of the two CPU’s, to guarantee the maximum precision. The two results are always compared, every difference produces a protection trip and consequent alarm.

For tuner management, antenna data and other working data are stored. Every band has a sub-band set, and for each of those, data related to the antenna and auto-ATU tuning is stored. The CAT and the frequency counter detect the operating frequency and the correct sub-band. Thanks to the stored data, the tuner and the antenna are automatically set correctly. The amplifier is equipped with two different memory banks, "Bank A" and "Bank B", which one can use to store two different configurations. This feature is particularly useful if one participates in a DXpedition. If one of the memory banks is set as home station, when back, just recall the proper memory bank. Furthermore, table driven management is useful to inhibit operation of the amplifier, for instance when an antenna for a particular band is not available. All auto-tuner functions remain, on standby, whilst using the transceiver only. Setting of the match data to write to the tables is performed automatically by pressing the [TUNE] key The system will then find the correct match for minimum SWR. To achieve a better match than that achieved with the automatic tune routine (most unlikely) it is possible to set the tuning manually by using the keys [◄C], [C►], [◄L], [L►]. When manual tuning has been performed, it is possible to read the tuning value, the working frequency and the associated sub-band on the appropriate screen page. Both the types of tuning are always effected in “STANDBY“ state. Before beginning the matching process, the tuner measures the SWR of the system cable / antenna. if it is greater than 3.5:1, the procedure does not begin and an alarm is given. It is possible to bypass the tuner with a specific command, in order to use an external tuner. NEVER USE THE INTERNAL TUNER WITH AN EXTERNAL ONE, it could seriously damage the linear. IF YOU WANT USE AN EXTERNAL TUNER, BEFORE EXCLUDE THE INTERNAL ONE. The internal tuner may be excluded: - Totally. - For single band. - For single band only with a specific antenna. It is always automatically excluded: - With the only receiving antenna set - With tunable antenna set. Note: the tuner, like all analog circuits, introduces a loss (0,8 dB max.) that may vary with tuning conditions. The power meter of the amplifier does not show this loss as the power is measured at the tuner input where the load resistance is always constant (50 ohm).

SET ANTENNA. Press [SET] and open the “ANTENNA“ menu page. Assign an appropriate antenna for the band concerned. If you don’t have an antenna for a band, input “N“. When all the antennas are programmed, exit and go back to STANDBY. USE OF AUTOMATIC TUNER. To complete the programming it is necessary to match the antennas to the amplifier by operating “TUNE“ function. (read the “TUNER“ chapter of the manual). We recommend that you select each band (with available antenna) and then program the tuner for the sub- bands within which you will operate. Refer to the table in section 19 of the manual to select the appropriate sub-bands for your operating preferences. You are strongly advised to proceed with the utmost accuracy, not just match the current frequency, but all matching all the antennas on all bands that are available, allows you to enjoy all the features of the automatic linear. To program the sub-bands, proceed as follows: 1) For every band find the central frequency in the table of each sub-band (refer to section 19 of the manual). Then set the transceiver to that frequency. 2) Next, set your transceiver to transmit a continuous tone (RTTY or FM). 3) Then press the [TUNE] key and then the PTT. The procedure for automatic tuning will start. You will hear the ATU relays operate and when they stop, the SWR will be at a minimum. Sometimes it is possible to improve tuning by repeating this step. 4) Repeat the previous steps for all sub-bands of bands you wish to use. 5) Repeat the previous steps for other antennas of the same band after having selected it using the [ANT] key. Note: if the ALC link is not used, it is preferable to reduce the transceiver power to about 30 Watts during this operation.
