4. General Description
4.1
Mechanical Description
The VJ1000HP is housed in a 19" rack-mountable frame, 14U high, of which 4U are
free and may be used for an exciter, a receiver or other equipment.
All controls and switches are situated on the front panel together with two analog meters.
There are no connectors on the rear panel.
Both the cooling air inlet complete with fan and filter, and the power cable entry hole may be
found on this panel.
A flue may be found on the top of the unit for the expulsion of hot air used for coooling the
unit, together with the RF output connector (to be connected to the antenna).
4.2
Electrical Description
The VJ1000HP is a tube amplifier with an earthed grid allowing a wide-band input (no
calibration across the band) from 87.5 to 108MHz.
This amplifier is able to generate an output power of over 1KW from an input power of
approx. 25W.
The amplifier features motorized anode and load matching across the entire operational
band.
The VJ1000HP is available in single phase version.
4.3
Controls and Indicators
Two analog meters are present on the front panel; one measures direct power output
and reflected power output (1 Fig.1), the other measures plate and grid currents (3 Fig.1).
The output power meter has only one scale 1KW f.s.,both for the measurement of the direct
power output and for reflected power output.
The meter for the measurements of the grid and plate currents has two scales too; one for
1A f.s.for the measurement of the grid current and for 100mA for the grid current.
For each of these meters there are the relative reading selector
(2 and 4 Fig.1).
In central position there are some switches and led indicators that concern to the plate and
load tuning: the two led indicators signal respectively the stop for the plate tuning at 87.5
MHz (6 Fig.1) and at 108 MHz (8 Fig.1), while the three selectorsare used rispectively for to
enable the engines of tuning (5 Fig.1), for the plate tuning (7 Fig.1) and for the load tuning (9
Fig.1).
Then there are three led indicators that signal alarms: for an excess of R.O.S. (10 Fig.1), for
insufficient fan pressure (11 Fig.1) and for an excess of grid current (12 Fig.1).
6 / 40
Rev. 4.0 - 26/02/01
USER MANUAL
VJ1000HP
The following are present on the front panel: an HT indicator which signals that the high
voltage supply is active; a switch to activate the HT supply, or put the unit in stand-by (ST.BY.
15 Fig.1); an on-off switch and corresponding indicator (14 and 16 Fig.1).
4.4
Protection System
The VJ1000HP features protection against: excess VSWR, excess grid current, opening
of panels with the unit active, and insufficient ventilation.
Under abnormal conditions the unit will be automatically disactivated; after 90 seconds the
protection system will re-activate the unit if the condition has returned to normal, unless a
panel is still open or the cooling system lacks sufficient pressure.
In this event, the procedure is repeated four times, after which the unit will remain disactivated
for 15 minutes.
If, after 15 minutes, the condition is still present, four more switch-on attempts are made,
after which the unit is shut down indefinately.
Should, during these cycles, the fault condition dissappear and the protection system succeed
in re-activating the unit for more than 15 minutes, the fault condition counter will be reset to
zero.
N.B. The times indicated above are approximate and may vary considerably.

5. Electrical Description
5.1
Introduction
This section describes in detail, the operation of the VJ1000HP.
For ease of description, the unit has been divided into sections, each of which is described in
detail, below.
5.2
Power Supply
The power supply, accessible via the rear panel, has been designed to be both rugged
and at the same time simple to maintain, allowing easy access to every component thus
easing repair work.
The power supply features a PI filter after the rectifying stage which attenuates spurious
components.
Two fuses provide overload protection.
The power supply comprises two separate transformers: the largest supplies the tube anode,
the other transformer supplies the tube's filament and supplies various functions such as
relays and the protection system.
This power supply is designed to work at single phase voltages.
5.3
Protection Card
This card is mounted in a metal box and fixed to the right-hand side of the RF chamber’s
chassis (6 Photo 2). This sub-unit has three alarm inputs which carry the signal to a comparator
which compares them to a pre-defined threshold. Should one of these inputs exceed the
alarm threshold, the amplifier is disactivated and a counter is started.
If the fault condition does not dissappear within the period defined by the counter, the unit is
shut down indefinately.
5.4
Tube
The ceramic/metal power triode 3CX1500A7/8877 has been designed to work in AB2
class amplifiers, in class B cathode-driven amplifiers, in audio or RF applications including
the VHF band, or in class C cathode-driven, anode-modulated RF amplifiers.
As linear amplifiers, they feature high power gain with low levels of intermodulation.
For the tube specification, see table C.

6. Installation Procedure
6.1
Introduction
This chapter contains information necessary for the installation and initial testing of the
VJ1000HP amplifier.
Is necessary, to not damage the amplfier, to execute the procedure below in the right
sequency.
6.2
Unpacking
Remove the unit from its packing and, before any other operation, ensure that the unit
has not suffered any damage in transit and that all its front panel controls are useable.
6.3
Fitting the Tube
To fit the tube follow the following instructions:
1)
Unscrew the screws holding the high voltage front panel (17 Fig.1) and open it.
2)
Check with care that the tube’s pins are correctly aligned with its socket.
3)
Insert the tube into its socket, pressing lightly and first rechecking the correct alignment
of the pins.
4)
Check that the tube is fully home in its socket, verifying the correct fit of the grid ring.
5)
Shut the high voltage panel and re-fit all the screws.
6.4
Connection and Setup Procedures
To connect the unit, follow the following instructions:
1)
Remove the rear panel.
2)
Connect a cable of suitable dimensions (the unit can draw up to 15A) to the power
input connector block.
3)
Connect the exciter supply cable to the corresponding connector block, taking care to
connect the earth (ground) to its correct connector.
4)
Connect a 50 Ohm coaxial cable (type RG 213) fitted with an "N" type male connector
to the input connector.
5)
Connect an antenna or a dummy load with an impedance of 50 Ohm to the output

6)
After having connected the 220 V driver supply and an RF output connector to the
driver, switch the VJ1000HP’s POWER switch to OFF and the ST.BY. switch to ON.
7)
Adjust the exciter power output control to minimum power.
8)
Connect the line supply (220V ±5%) to the unit.
9)
Switch the POWER switch to ON, the corresponding indicator will show the presence of
the line supply in the unit and, at the same time the cooling fan will start.
Normally the PRESS. indicator will stay on for a few seconds before the fan has created
sufficient air flow.
After 2-3 minutes of warming up, the HT indicator will light up; simultaneously the
characteristic noise of the power solenoid will be heard indicating that the anode supply
is active.
The driver will also be active.
The unit without excitation will absorb about 80 mA of anode current.
10) Switch the OUTPUT POWER switch to DIR and the CURRENTS switch to PLATE.
11) Adjust the exciter power control to obtain a anode current of
150/200 mA.
12) Using the TUNING switch, activate the tuning motors so that both green leds next to the
PLATE control light up.
Holding the TUNING switch down, use the PLATE "+" or "-" control (the unit is factoryset to a frequency of 98 MHz) to tune the anode circuit.
"+" indicates an increase in frequency, and "-" a reduction in frequency.
If one of the leds switches off, this indicates that the end of the frequency range has
been reached and that no more adjustment is available in that direction.
The OUTPUT POWER meter can be used to tune the anode circuit; maximum
meter reading (maximum output power) corresponding to correct tuning.
13) The LOAD tuning procedure follows in a similar fashion: holding down the TUNING
switch, adjust the LOAD control for maximum output power.
REPEAT STEPS 12 AND 13 SEVERAL TIMES TO OBTAIN THE OPTIMUM SETTINGS
14) Increase exciter power until an output power of 800/850 W is obtained and repeat steps
12 and 13.
Note: The driver power don't never must excess 25W, then the maximum Plate current
is 500mA and the maximum Grig current is 35mA
15) With output power at 1000 W, make small adjustments, as above, to minimize
grid and anode currents; if necessary, reduce exciter power to maintain 1000 W of
output power.

Fault Finding during the Setup Procedure
The following fault conditions may occur during the setup procedure:
1)
THE RED LIGHT "PRESS." STAYS ON
Check that the rear air filter is not blocked and that there is at least 40/50 cm clearance
between the rear of the unit and any obstructions such as a wall.
Check that the air exit flue is free from obstruction.
2)
THE S.W.R. INDICATOR LIGHTS UP DURING THE TUNING PROCEDURE
Check for standing waves on the antenna with a wattmeter. The reading should be less
than 100 W.
3)
THE GRID INDICATOR LIGHTS UP DURING THE CALIBRATION PROCEDURE
Reduce output power and carefully re-tune the output (LOAD and PLATE).
WARNING:The inside of the unit operates at high voltages which are dangerous and
potentially lethal. For this reason the unit should only be operated with all
its panels securely in place. The unit must be connected to a good earth.
The unit should be operated in a well ventilated environment the hot air
expelled by the unit will rapidly raise the temperature of a poorly ventilated
environment with potentially damaging consequences.
Should operation of the unit be inhibited by the protection system, do not
attempt to re-activate the unit without carefully checking operating and
environmental parameters.
4)
THE EQUIPMENT DOESN’T SUPPLY THE NOMINAL POWER INDICATED ON THE
TEST REPORT ALTHOUGH THE ADJUSTMENT OPERATION IS BEEN MADE
CORRECTLY.
Verify that the line voltage, under load, has the nominal value ±5% max.
Verify the COS-FI value on the line; this value must be better than 0.9.
Otherwise correct the power factor of the line.

7. Maintenance Procedure
7.1
Safety Procedures
WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
When the amplifier is operational with the rear panel removed, lethal voltages are easily
accessible.
Use properly insulated tools for any calibration work and do not make contact with any internal
components.
Ensure that all high voltage components have been grounded (use an earthing stick).
Ensure that power has been disconnected from the unit before any maintenance work is
started.
FIRST LEVEL OF MAINTENANCE
7.2
Routine Maintenance
The only routine maintenance required by the amplifier is periodic changing of the fan,
air filter and removal of accumulated dust from inside the tube cavity and from the air filter.
The periods between routine maintenance will depend upon operating conditions, ambient
temperature, ambient dust levels and humidity. It is advisable to carry out preventative checks
at 3 month intervals and to change fans at least every 18 months, or before if they become
noisy or show signs of wear.
Periodic replacement of the tube will also be necessary.
The operating life of the tube is very dependant upon operating conditions, for example: line
voltage fluctuations over ±5%, temperatures over +30°C, high humidity, the presence of dust
and incorrect calibration of the amplifier will all result in a greatly reduced tube life.
SECOND LEVEL OF MAINTENANCE
7.3
Replacement of Components
N.B. TO RE-ASSEMBLE THE UNIT, SIMPLY REVERSE THE SEQUENCE OF
OPERATIONS.
N.B. THE FOLLOWING PROCEDURE SHOULD ONLY BE CARRIED OUT BY QUALIFIED
PERSONNEL USING THE CORRECT TOOLS AND EQUIPMENT. UNQUALIFIED OR
INEXPERIENCED PERSONNEL NOT USING THE CORRECT TOOLS AND
EQUIPMENT CAN EASILY CAUSE DAMAGE TO THE UNIT WHICH WILL
IMMEDIATELY INVALIDATE THE GUARANTEE.

8. Calibration Procedure
N.B. THE FOLLOWING PROCEDURE SHOULD ONLY BE CARRIED OUT BY QUALIFIED
PERSONNEL USING THE CORRECT TOOLS AND EQUIPMENT. UNQUALIFIED OR
INEXPERIENCED PERSONNEL NOT USING THE CORRECT TOOLS AND
EQUIPMENT CAN EASILY CAUSE DAMAGE TO THE UNIT WHICH WILL
IMMEDIATELY INVALIDATE THE GUARANTEE.
8.1
Frequency Changes
To change the operating frequency of a tube amplifier the following procedure is required:
1)
Select the desired frequency on the exciter.
2)
Reduce exciter power to minimum power.
3)
Connect the line supply (220V ±5%) to the unit.
4)
Switch the POWER switch to ON, the corresponding indicator will show the presence of
the line supply in the unit and, at the same time the cooling fan will start.
Normally the PRESS. indicator will stay on for a few seconds before the fan has created
sufficient air flow.
After 2/3 minutes of warming up, the HT indicator will light up; simultaneously the
characteristic noise of the power solenoid will be heard indicating that the anode supply
is active.
The driver will also be active. The unit without excitation will absorb about 30 mA of
anode current.
5)
Switch the OUTPUT POWER switch to DIR and the CURRENTS switch to PLATE.
6)
Adjust the exciter power control to obtain an anode current of 200mA.
7)
Using the TUNING switch, activate the tuning motors so that both green leds next to the
PLATE control light up.
Holding the TUNING switch down, use the PLATE "+" or "-" control (the unit is factory
set to a frequency of 98 MHz) to tune the plate circuit.
"+" indicates an increase in frequency and "-", a reduction in frequency.
If one of the leds switches off, this indicates that the end of the frequency range has
been reached and that no more adjustment is available in that direction.
The OUTPUT POWER meter can be used to tune the plate circuit; maximum meter
reading (maximum output power) corresponding to correct tuning.
8) The LOAD tuning procedure follows in a similar fashion: holding down the TUNING
switch, adjust the LOAD control for maximum output power.
30 / 40
Rev. 4.0 - 26/02/01
USER MANUAL
VJ1000HP
REPEAT STEPS 7 AND 8 SEVERAL TIMES TO OBTAIN THE OPTIMUM SETTINGS
9)
Increase exciter power until an output power of 800/850 W is obtained and repeat steps
7 and 8.
10) With output power at 1000 W, make small adjustments, as above, to minimize grid and
anode currents; if necessary, reduce exciter power to maintain 1000 W of output power.
8.2
Calibration of the Protection Card
Before calibrating the protection board, or IG and IA currents, remove the front panel
which also supports the RF chamber.
Disconnect the antenna output cable, remove the coaxial cable from the input connector,
undo the 8 screws holding the panel and remove the panel; take care not to disturb the high
voltage cables and the multipolar service cable.
Lay the chamber carefully on a raised surface, opposite the unit to facilitate the following
procedure.
The protection board has three trimmers for adjusting the following alarm thresholds:
insufficient fan pressure, excess V.S.W.R. and excess grid current.
These alarm conditions are indicated by three leds (Alarms Fig.1).
Remove the metal cover of the protection box by undoing the 4 screws.
The alarm thresholds may be calibrated through the following procedure:
1)
CALIBRATION OF FAN PRESSURE ALARM THRESHOLD (PRESS.).
a)
Switch the ST.BY. switch (15 Fig.1) to ST.BY.
b)
Enable power to the unit by switching the POWER switch (16 Fig.1) to ON.
c)
Ensure that the PRESS. indicator (11 Fig.1), initially on, turns off when the air-flow
switch (3 Photo3), positioned inside the flue, switches up (air pressure normal).
Two error conditions can prevent the above sequence from being completed: the indicator
remains on, or remains permanently off.
In this case adjust the trimmer, R4, until the sequence is completed correctly: switch
down, led on; switch up, led off.
2)
CALIBRATION OF V.S.W.R.
To adjust the threshold of the V.S.W.R. alarm first perform SETUP1 (Fig.3). The threshold
should be set at around 10 % of the maximum output power i.e. of 100W.
a)
Connect a mismatched, dummy load (e.g. 25 Ohms 1.5KW) to the RF output of the
amplifier, in series with a bypass wattmeter.b). With the unit switched on (N.B. the rear
cover must be in place) and having calibrated the unit to its exciter frequency, gradually
increase the output power from 0W until a reflected power of 100W is registered on the
external wattmeter.
c)
Adjust the trimmer R7 until the alarm threshold is reached and the V.S.W.R. led lights
up (10 Fig.1).

VJ1000HP
N.B. Several attempts may be necessary. At least 60 seconds should be allowed
inbetween attempts to allow an automatic reset.
3)
CALIBRATION OF THE GRID CURRENT (IG) ALARM THRESHOLD
a)
Connect the unit to the line supply and connect a dummy load (50Ohms 1.5KW).
b)
Switch the ST.BY. switch (15 Fig.1) to ST.BY.
c)
Wait for the fan to build up pressure.
d)
Perform the SETUP 3 procedure and steps required to calibrate the grid current IG
(paragraph 5.5).
e)
Adjust the reading (regulating the supply) to 40 mA.
f)
Adjust trimmer R21 until the IG protection is activated i.e. when the IG indicator (12
Fig.1) comes on.
g)
Reduce the indicated current to 30 mA.
h)
Wait for the automatic protection cycle to complete and repeat step e) to verify the
correct alarm threshold (40 mA).
8.3
Calibration of the PWR Meter (REF)
Perform the calibration procedure for the V.S.W.R. protection upto step b) (paragraph
5.2 (2)).
At this point verify that the VJ1000HP meter reading is correct; adjustment may be made
with trimer R6 situated in the directional coupler on the output of the low-pass filter, near the
antenna connector.
To gain access to it, remove the small protection cover.
8.4
Calibration of the PWR Meter (FWD)
Perform SETUP 2 (Fig.4).
1)
Connect a 50 Ohm 1.5KW dummy load in series with a bypass wattmeter (Byrd model
43), switch on the amplifier and verify the correct reading of the VJ1000HP’s meter.
2)
Adjust trimmer R9, situated inside the directional coupler on the output of the low-pass
filter, near the antenna connector.
3)
To gain access, remove the small protection cover.
N.B. The trimmer R2 connected in series with the meter allows small adjustments
after the calibration of PWR, REF and FWD, and is normally in a central position.

10. Telemetry Card Option
10.1
Calibration of the Voltages on the Telemetry connector
The VJ’s internal Telemetry connector gives to the external the voltages referred
to the various values under control. The voltage related to the Forward Power
output is 1,6V for 1KW. To calibrate this voltage follow the procedure below:
1-
Adjust the power of the machine to the nominal value of 1KW.
2- Adjust R13 on the Telemetry Card to obtain a voltage, between pin 16 and
pin 1 of Telemetry connector, of 1,6V.
The pin 4 gives the voltage referred to measurment of the Reflected Power. This
voltage is 1,4V for 100W (10% of 1KW). To calibrate this voltage follow the
procedure below:
1-
Adjust the Reflected Power to 100W using a wattmeter Bird in output.
2- Adjust R14 of Telemetry Card to obtain a voltage, between pin 14 and pin 1
of connector, of 1,4V.
3-
10.2
Adjust R36 to set the Power Good threshold.
Wiring Connections details
1- The exciter is not supplied from the Service Connector but separataly. This is
because if there was no high voltage, the Service Connector would be not
supplies instead, too. The exciter shall be ever ON.
2- A system that closes to earth a BNC contact when the machine is in Standby
mode is used. This contact is connected with a BNC-BNC cable to the Interlock/
RF Mute connector of the exciter. When the VJ goes in Standby status, the
exciter enters in RF Mute mode. The contact that permits this functionallity is
located on the Service teleswitch.
3- A Reset (or Restart) button is connected between pin 9 and earth of Telemetry
Card JP2 connector and it’s located on the front panel. It’s used to give the
same kind of signal as the an exciter that an PTXLCD gives when it is switches
ON. This operation resets the alarms and the remote control relay, in case the
amplifier is in OFF status and there is not an exciter able to change it to the ON
status.
4- The Alarms Card is supplied by the alternate current that first passes throught
JP3 (pin 1 and 2) of telemetry. When the Telemetry Card receives the REMOTE
OFF command, Alarms Card turns OFF itself. This permits to remotly reset the
alarms throught an ON-OFF-ON sequency. Please remember that after 6
attempts failed the machine will block itself. This remote control system gives
a remote reactivation mechanism.
5- A green LED is mounted between the point S of the Alarm Card and ground
(throught a 2K2 resistor); this is to indicate whether the Alarms Cards is supplied
38 / 40

VJ1000HP
or not.
6- The DB25/telemetry connector cable is connected as shown in the diagrams
in appendix.
7- The system is the same for VJ1000 and VJ2000.
10.3
General Verifications
-
When Standby mode and operating the ralated switch, the exciter shall go in
RF Mute mode.
-
VJ1000/2000 shall switch to Standby mode if the exciter put in the OFF status.
-
If the VJ has completed a reset cicle for 6 times and it’s thus blocked, a series
of ON-OFF-ON of the exciter shall reset the alarms.
-
Only the SWR ANT Alarm is telecontrolled.
