GENERAL INFORMATION
(Read the specific chapters for more details).
2.1
Power supply
The amplifier’s power supply is 230 / 115 Vac (230 Vac default).
The main switch [I/O] is located on the rear panel, in the [O] position all the internal
circuitry is powered off, in the [I] position (red led ON) it is possibile turn ON or turn OFF
the linear amplifier in one of the following ways:
a)
Using the [ON] /[ OFF] keys on the front panel.
b)
Applying / removing 9 -15 Vdc on pin (8) of the CAT connector.
c)
Using the RS232 port and the management software. It is possible to
download this software from the website www.linear-amplifier.com .
NOTE: When turned ON, almost all transceivers output 13,8 Vdc. With this voltage, the linear
amplifier can be turned automatically ON / OFF at the same time as the transceiver.
2.2
Input / Output
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.
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.
2.3
ALC / RELAY / CAT
There are two transceiver inputs (IN 1, IN 2), to allow two different transceivers to be
connected at the same time.
ALC
Is a voltage (0, -11 Vcc) generated by the amplifier, it is used to control the
output power of the transceiver. In this way the power from the amplifier may
be automatically controlled. This link is recommended.
If the ALC port is not connected, it is ncessary to manually regulate the drive
power from the transceiver.
RELAY
This essential link allows the amplifier to be put in the transmit state. To do
that it is necessary that the inner pin of the phono connector is connected to
signal ground. This is normally done at the transceiver with either a close on
ground relay, or with a switching transistor. It is important that the voltages at
that terminal do not exceed 12 Vdc. On the transceiver this link is often called
SEND or TX GND. Refer to your transceiver manual for more details.
CAT
Thanks to this link the linear amplifier will detect the operating frequency of
the transceiver and then automatically control changes of band, antenna and
automatic antenna tuner. 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:

The linear amplifier can be used in the following ways:
1) OFF
2) STANDBY
Only direct connection between INPUT 1 and ANT 1 exists.
All the functions are activated (band change, antenna change, tuner
control) but the transmission is from the transceiver only.
3) OPERATE All the functions are activated and the transmission is using the
linear amplifier.
NOTE: Regulation of the exciter’s power is automatic through the ALC connection (the
maximum power in STANDBY, the neeted power in OPERATE).
Without the connection, you have to manually regulate the exciter’s power..
NOTE:
For continuous duty cycle transmissions (RTTY, PSKxx, SSTV, FM, AM etc.) we
recommend switching the power to “HALF“ state.

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.
The inductance of such a connection has to be low, so the connection to ground should
be as short and direct as possible. Large-section copper conductors should be used for
this purpose. Terminating the earth connection with a small metal plate is suggested.
The best solution is to have a ground stake, driven into the ground, and used only for
the radio station.
Often good results can be acheived using correct earthing clamps, connected to the
mains water supply pipe (attention, most water pipes are now in plastic).
DO NOT use central heating pipework.
AVOID the electric circuit ground of the building ( to be used for the 50/60 Hz safety
only ).
WARNING! DO NOT connect to gas pipes because there is danger of explosion !!
6.
ANTENNA
Because this is a high-power amplifier, it is necessary to use correctly-rated antennas
and feedline cables.
Take special care with antennas with traps, because trap warming can occur during
periods of high-power transmission and a high SWR can result.
Always use antennas with SWR less than 1,6:1, even if the tuner is able to overcome
some mismatches greater than 3:1.
With the tuner the PA is matched, but with a high VSWR, the cable is mismatched and
there can be consequent loss of power, heating and high voltages present.
It is suggested that suitable static protection be given to antenna feeder cables.

EXPERT 1K-FA
POWER SUPPLY
The power supply unit of the SPE Expert 1K-FA has two blocks with two separate
power transformers.
The first block has regulated and protected voltages, and powers all the electronic
circuits for command and control.
The second block powers only the PA. It has a toroidal transformer with a low magnetic
field to avoid disturbances to nearby equipment. The output voltages are 44 Vdc (on
Full-power mode) and 30 Vdc (on Half-power mode), regulated with SCRs that also
provide ‘soft start’ on switch-on.
This design was adopted as it provides maximum efficiency and therefore less heat to
dissipate.
7.1
Mains cable termination
Your dealer will ensure that a mains plug appropriate for the country of use is fitted.
If the amplifier is used in a country other than that of the original purchase, refer to your
dealer for assistance.
The default mains voltage supply of the amplifier is 230 Vac (210-250Vac).
To change this to 115 Vac (105-125 Vac). (USA customers and other countries with 115
Vac supplies) see below:
WARNING! - REMOVE THE MAINS CORD FROM THE WALL SOCKET AND
WAIT AT LEAST 2 MINUTES FOR CAPACITORS TO DISCHARGE.
Only then, remove the bottom cover, the plastic protection and connect following the

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.
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.
For every input there is a different table. If two exciters are connected at the same time,
each exciter can have different configurations.
It is possible to use the two different tables when the amplifier operates at two different
locations. In fact it is possible to use the INPUT 1 at one and INPUT 2 on the other. In
this way repeated reprogrammings are not needed
In the US version, operation on the 12 m and 10 m bands has been inhibited following
FCC regulations. Authorized 12/10m operation of the amplifier by licensed radio
amateurs will be enabled by the dealer there in accordance with current rules.
The auto-tuner and antenna selection via the amplifier are still enabled even in 12/10m
inhibited units.
All auto-tuner functions remain, on standby, whilst using the transceiver only.
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.
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.
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).
NOTE: ATTENTION, When the amplifier is on the ‘STANDBY’ or ‘OPERATE’ modes, always
disable the automatic tuner in your transceiver.

EXPERT 1K-FA
PROTECTIONS / ALARMS
The SPE 1K-FA has a sophisticated protection system that constantly controls the
amplifier’s most important parameters.
These parameters are:
Temperature of the heatsink; max. / min. voltage on the PA; max. PA current; SWR;
reflected power; max voltage 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.
NOTE: To guarantee the maximum efficiency with the same output power, the PA has three
MRF150 push-pull amplifiers connected through a combiner.
NOTE: Temperature measurement is used also to control fan speed. The thresholds where the
speed changes may be changed from NORMAL (default) or CONTEST (See the
“Programming” chapter of this manual).
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.
There are three types of protections/alarms:
a) SIMPLE
b) SERIOUS
c) FATAL
This is the most common case. An acoustic warning beep
sounds, but no operator intervention is required, as the control
system automatically restores the correct operating conditions.
When automatic system recovery is not possible (e.g. the
temperature climbs over the limits due to obstruction of the fans,
SWR is too high, etc.). In this case the amplifier switches into
standby state and the alarm is stored. Normally transmission can
continue with the exciter only.
If the amplifier is in the b) situation but the CPU is faulty or it isn’t
able to operate, the amplifier is turned OFF with no other
warning. To restart the amplifier, the main switch in the rear
panel has to be set first to [O], and then to the [I] position
NOTE: It is possibile to read the alarms file log in the standby state using the [DISPLAY] key.
To reset the alarm file log press the [TUNE] and [OPERATE] keys together.
NOTE: If the acoustic alarm is very frequent during transmission, the possible causes should
be investigated.
Pag. 17 of 42
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.
If the temperature is allowed to rise further, then a “SERIOUS“ alarm will eventually
be activated.
NOTE: During a SERIOUS alarm, there is an acoustic alarm for 30 sec. Pressing the
[DISPLAY] key, the system changes to ‘STANDBY’ state immediately.

User’s manual
b) CAT
EXPERT 1K-FA
Allows you to program the amplifier to accept control commands from
specific transceiver types.
You may need to refer to your transceiver user manual to ensure that
it is correctly programmed to handle such a link.
Select the brand or function:
- SPE
- ICOM
- KENWOOD
- YAESU
- RS232
- NONE
No further programming is necessary, all is already
programmed for the SPE transceivers.
You need to choose between “CI-V“, or “Band Control
Voltage “ if you use the analog connection (read the “CAT
CONNECTION” chapter of this manual).
If you choose “CI-V“, you also need to choose the baud rate
which is usually 9600.
You have to choose the baud rate (almost always 9600).
If you use the CAT connection (read the “CAT
CONNECTION” chapter of this manual), select the model of
the transceiver and than select the baud rate (almost always
4800). If the model isn’t in the list, select “Band Data“ (read
the “CAT CONNECTION” chapter of this manual).
With a proper protocol it is possible to use this port not only
as a remote control but also as a CAT port (useful to link the
linear with any customer application).
Download the protocol specification from the website
www.linear-amplifier.com
Program when there isn’t a link with the Transceiver.
The amplifier frequency counter will then be used .
NOTE: If using the CAT, check that the baud rate of your transceiver is set to the same value as
you program to the amplifier.

11. INITIAL OPERATION OF THE AMPLIFIER
Before turning ON the amplifier, the following preliminary operations are necessary:
1)
2)
3)
4)
5)
Read this manual with care.
Be sure that the amplifier is correctly set for the local mains voltage supply.
Connect the linear to ground circuit
Connect the antennas.
Connect the amplifier to the transceiver (read the “CONNECTIONS WITH
THE TRANSCEIVER” chapter of this manual)
Operate [I] the main switch on back panel, and press the [ON] key on the front panel.
Select the INPUT for the transceiver, and always carry out programming with the
amplifier in STANDBY. If you change INPUT you have to repeat this programming.
NOTE: You may have to repeat some programming if you change antenna, transceiver,etc.
NOTE: ATTENTION the ‘RELAY’ and ‘CAT’signals in some types of transceivers are only
turned ON from a transceiver MENU. Refer to the user manual.
NOTE: ATTENTION, when the amplifier is on the ‘STANDBY’ and ‘OPERATE’ modes, always
disable the transceiver auto-ATU.
11.1 Initial Programming
You must carry out the next steps in the sequence below:
a) 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 “NONE“.
When all the antennas are programmed, exit and go back to STANDBY.
To verify the correctness of the programming, press the [ANT] key, the
band / antenna programmed will be shown.
b) Set CAT.
Press [SET] and enter the “CAT“ menu page.
Select the transceiver brand and progress with programming according to the
type of connection between the amplifier and the transceiver (read the “CAT
CONNECTIONS” chapter of this manual).
At the end of programming, exit and go back in STANDBY.
To verify the correctness of programming, press the [CAT] key, and all the
data stored will appear on the display.
To verify the correct “CAT” operation, press [SET] and select “MANUAL TUNE”, While
changing your transceiver VFO, you should see the amplifier frequency display follow.
Then return to STANDBY.
Pag. 22 of 42
User’s manual
EXPERT 1K-FA
In the same way, if “BAND CONTROL VOLTAGE“ or “BAND DATA“ are connected,
check that the amplifier follows band changes at the transceiver.
If it does not, verify that your programming (or your link) has been done correctly.
d) Use of Automatic Tuner
To complete the programming it is necessary to match the antennas to the
amplifier by operating “TUNE“ (read the “TUNER“ chapter of this manual).
We recommend you to select each band (with available antenna) and then
program the tuner for the sub-bands within which you will operate.
efer to the table in section 18 of this manual to select the appropriate
sub-bands for your operating preferences.
Progress as follows:
1) Find the central frequency of the sub-band to tune in the table (refer to
section 18 of this manual) and set the transceiver to that frequency.
2) Press the [TUNE] key.
3) Set your transceiver to transmit a continuous tone in RTTY or CW. The
procedure for automatic tuning will start and then it will stop when SWR is
at a minimum. Sometimes it is possible to improve tuning by pressing the
[TUNE] key again.
4) Repeat the previous steps for all bands and sub-bands you want.
NOTE: If the ALC link is not used, it is preferable to reduce the transceiver power
to about 50 Watts during this operation.
NOTE: As a default, the table is programmed for standard 50 ohm out. If, for a
band, you want to reset to default programming,progress as follows:
- Go to the “ANTENNA“ menu page and set this band to “NONE“,
then exit from that page.
- Go to the “ANTENNA“ menu page again, assign the appropriate
antenna to this band, then exit from that page.
The programming will be reset for 50 ohm output.
The initial programming concludes after steps a), b), c).
11.2 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.
During transmission check the parameters on the display always, because SPE has
selected, designed and adjusted them with care.
SPE recommends (using the ALC link) that the transceiver should be set to its
maximum drive power.
To reduce the amplifier output, if required, it is then necessary only to set the amplifier
to “HALF” power state rather than changing the transceiver drive power.
Of course you may also regulate continuously the amplifier output power by changing
the level of drive power from your transceiver.
If less output power than 500 Watts is desired, it is preferable, for best efficiency, to
start to reduce drive from the “HALF” power state.
Pag. 23 of 42
User’s manual
EXPERT 1K-FA
SETTING DRIVE LEVELS
a) SSB:
Regulate the “MIC GAIN” of the transceiver until, speaking normally into
the microphone, the signal peaks on the display don't quite reach the
maximum rated output power. Monitoring the transmission is a good way
of checking your settings. If there is however some distortion, decrease
the “mic gain” or decrease the power of the transceiver until a small
reduction of the output power of the amplifier is seen.
b) CW:
In key down, you get the maximum output power automatically. Check the
“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
from the transceiver. In case of very heavy use, it is advisable to work in
“Contest” condition to take advantage of the greater efficiency of the fans.
d) AM
This transmission mode radiates a continuous carrier which is 25 % of its
PEP value (400W PEP AM = 100W carrier power). SPE recommends you
always operate in ‘HALF’ mode for AM. To get an output signal without
distortion, proceed as follows: transmit the AM carrier only, with your
transceiver “MIC GAIN” set to zero, and no modulation. Set the
transceiver without exceeding 125W of carrier output from the amplifier.
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 500W. Note that because of the
modulation characteristics of AM, the average value shown will normally
be much less. SPE suggests you monitor your transmission to check that
the “MIC GAIN” setting is correct. In case of very heavy use, it is advisable
to work in “Contest” condition to take advantage of the greater efficiency
of the fans.
NOTE: If you choose to set the output power of the amplifier by varying the output power of
the transceiver, the ALC connection is not required.
NOTE: ATTENTION, never stress uselessly the amplifier with long periods in key-down, it can
be a possible cause of damage.
NOTE: ATTENTION, in SSB the use of the compressor, only when necessary, strongly reduces
the increase of the temperature.

16. MAINTENANCE
The Expert 1K-FA linear amplifier doesn’t need internal maintenance because it has a
cover without ventilation holes. No tube-type EHT is used so the high voltages present
in tube amplifiers, which sometimes attract dirt, are not present.
The user has only to periodically check the cleaning of the air filter on the front panel.
The frequency of such operation depends how dusty the amplifier location is and how
much it is used. We recommend monthly cleaning of the filter.
To clean the filter
a)
Remove the front grid.
b)
Remove the filter and clean it with care.
c)
Reassemble the filter and the grid after having carefullly cleaned the
mechanical structure that includes them.
NOTE: Check the filter if an unexpected rise of temperature is noticed.
NOTE: Never operate without the filter, as dust could be deposited on the surface of the
heatsink limiting its ability to cool.
NOTE: To allow the most efficient heat-dissipation, large copper parts have been used.
