Page 14: So2R (Single Operator Two Radio )
RTX1 and RTX2.. A careful design is needed to avoid such a danger which could be devastating for the receivers. This possibility is available with the optional external unit "SPE SO2R1" according to the following diagram. Pag. 14 di 14... -
Page 15: Band-Pass Filters Set "Spe Bpf1
In this case the amplifier is connected to a single transceiver (INPUT 1 / 2). "SPE BPF1 automatically selects the filter on the band to be used in the input where the transceiver is connected, while the other unrelated input is unused. - Page 16 In this case the amplifier is connected to two transceivers. "SPE BPF1" automatically selects the right filters and the right inputs as well. These features can be possible also with the simultaneous use of the unit "SPE SO2R1, (use the AUX port with a Y cable).

Page 19: Setting Up A Single Antenna For Reception
In some cases it may be appropriate to transmit with an antenna and receive with a more appropriate one. A unique feature allows the Expert 2K-FA to set a receiving antenna and to provide an its automatic switching after transmission. -
Page 20: External Ground Connection
User manual EXPERT 2K-FA EXTERNAL GROUND CONNECTION WARNING! Before connecting an external ground as described below, check with a qualified electrician that your national wiring codes permit such a connection. To reduce TVI, BCI and other RF problems it is sometimes helpful to connect the amplifier to a good RF ground. -
Page 21: Antenna
User manual EXPERT 2K-FA ANTENNA Because this is a high-power amplifier, it is necessary to use correctly-rated antennas, connectors and feedline cables. Take special care with antennas using baluns, traps, because balun / trap warming can occur during periods of high-power transmission and a high SWR can result. -
Page 22: Power Supply
EXPERT 2K-FA POWER SUPPLY The power supply of the SPE Expert 2K-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, it consists of two separate elements. -
Page 23: Tuner (Atu)
User manual EXPERT 2K-FA TUNER (ATU) The amplifier has an automatic tuner that handles load mismatches up to 3:1 VSWR (2.5:1 for 6 m). The amplifier contains a look-up table with all the permitted bands. For tuner management, antenna data and other working data are stored. - Page 24 User manual EXPERT 2K-FA Note: ATTENTION: When the amplifier is either in “STANDBY” or “OPERATE” mode, always disable the automatic tuner in your transceiver. Note: ATTENTION: As two different tables are used for INPUT1 and INPUT2, it is necessary to make separate matching, for the same antenna, depending on the used input.

Page 26: Programming
User manual EXPERT 2K-FA 10. PROGRAMMING The three [SET], [◄▲] and [▼►] keys, underlined with an orange line, permit programing the amplifier and they can be used in the following way: [SET] Use it to open the menu page, to validate the choices and to exit from the menu page. - Page 27 Select the brand or function, for the proper link see "CAT CONNECTIONS" on this manual. - SPE No further programming is necessary, all is already programmed for the SPE transceivers. - ICOM Set the “CI-V“ protocol, you also need to choose the baud rate which is usually 9600.
- Page 28 User manual EXPERT 2K-FA c) MANUAL TUNE Allows you to tune the amplifier manually, however achieving a better setting than that obtained by automatic tuning is very unlikely. Set your exciter to transmit a continuous RTTY or CW signal. Press the [◄ L], [L ►], [◄ C], [C ►] keys until you obtain the minimum SWR.

Page 29: Initial Operation Of The Amplifier
User manual EXPERT 2K-FA 11. INITIAL OPERATION OF THE AMPLIFIER Before turning ON the amplifier, the following preliminary operations are necessary: Read this manual with care. 1) Be sure that the amplifier is correctly set for the local mains voltage supply. -
Page 30: Operating
You need few precautions when using the amplifier thanks its high level of automation. ALC and CAT links are highly recommended. If ALC is not used, SPE reminds you that it is better to lose a fraction of dB in transmitted power, by slightly reducing the drive power, than to over-drive the amplifier and have a poor quality transmission. -
Page 31: Setting Drive Levels
Then, speaking into the microphone normally, set the” MIC GAIN” of the transceiver until the peak output power, on speech peaks, as shown on the amplifier display, is no more than 1 KW or 500W. SPE suggests you monitor your transmission to check that the “MIC GAIN” setting is correct. -
