Page 9: General Information
Most modern tranceivers have CAT control. In old models often, analog or digital information are sent for changing band. The SPE Expert 1K-FA, thanks to an efficient frequency counter, constantly controls and verifies data coming from the transceiver. Automatic management of bands, antennas and tuner can be done in the following way: Pag. - Page 10 User’s manual EXPERT 1K-FA In recent ICOM, YAESU, KENWOOD models, through CAT. In the older ICOM models, through “Band Control Voltage”. In the YAESU models not listed, or without CAT, through "Band Data". In every other case through the frequency counter.

Page 16: Tuner
User’s manual EXPERT 1K-FA TUNER The amplifier has an automatic tuner that handles load mismatches up to 3:1 VSWR (2,5:1 for 50 MHz). The circuit used is a PI – L network with excellent harmonic suppression. The amplifier contains a look-up table with all the permitted bands. -
Page 17: Protections / Alarms
RF on the tuner; input power; power combiner balance. NOTE: Unlike all the other linear amplifiers that measure only the reflected power of the antenna, to guarantee a greater protection of the PA, the SPE amplifier measures also the power of harmonics reflected by the band-pass filter. - Page 18 User’s manual EXPERT 1K-FA NOTE: Before the temperature limits are reached, the output power will change from FULL to HALF automatically, so that transmission with the amplifier may continue with reduced power. In SSB the use of the compressor, only when necessary, strongly reduces the increase of the temperature.

User’s manual EXPERT 1K-FA 10. PROGRAMMING The three [SET], [◄▲] and [►▼] keys, underlined with an orange line, permit programing the amplifier and they can 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 20 Select the brand or function: - SPE No further programming is necessary, all is already programmed for the SPE transceivers. - ICOM You need to choose between “CI-V“, or “Band Control Voltage “ if you use the analog connection (read the “CAT CONNECTION”...
- Page 21 User’s manual EXPERT 1K-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 22: Initial Operation Of The Amplifier
User’s manual EXPERT 1K-FA 11. INITIAL OPERATION OF THE AMPLIFIER Before turning ON the amplifier, the following preliminary operations are necessary: Read this manual with care. Be sure that the amplifier is correctly set for the local mains voltage supply. -
Page 23: Operating
You need few precautions when using the amplifier thanks its high level of automation. 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 24 “PW REV”. If it shows more than 120/140 Watts, decrease the power of the transceiver until that value or less is noted. c) RTTY, DIGITAL MODES, SSTV, FM: SPE recommends you operate in ‘HALF’ mode because these types of transmission have a very high duty cycle. Check “PW REV”, and if it shows more than 120/140 Watts, decrease the power...
