Congratulations!
We are happy that you have selected the JUMA PA1000 linear amplifier.
You will find it easy to use. We hope you enjoy using your JUMA PA1000.
Safety warnings!
Dangerous voltage inside JUMA PA1000.
Check that your mains AC voltage is the same as marked on the rear panel.
Use a AC mains socket with a protective earth.
If a mains protective earth is not available connect your station ground to the rear panel ground terminal.
If you need to change the mains fuses switch OFF the power with the rear panel rocker switch and remove the mains
cable from the power entry module and that wait at least 5 minutes before fuse change.
Before opening the enclosure switch OFF JUMA PA1000 with the rear panel rocker switch and disconnect the mains
cable. After that wait at least 5 minutes before opening the enclosure.
DO NOT use JUMA PA1000 without enclosure.
Cautions!
Do not drive more than 25 watts RF to the TRX input connector.
Some transceivers may transmit up to 100 W for a short time although you have selected 10 W output. To avoid
MOSFET failure keep the EXCITER MAX PWR setting at 100W until you are ABSOLUTELY SURE that your transceiver is
not momentarily transmitting more than selected. See settings instructions.
Roller-inductor tuners are the most troublesome of all tuners. The "hot-tuning" roller-inductors is a serious concern
for all transmitters, and even to some vacuum-tube transmitters. The problem with these tuners is that the electrical
continuity between the roller, the spring-loaded rod on which it slides and the coil seldom remains continuous
conductivity, especially whilst the roller is in motion. Very high voltage transients during tuning of a roller-inductors
are a well-known cause for damage. Thus, any antenna tuner, especially a roller-inductor tuner should be adjusted at
the lowest practicable RF power level, or even with an antenna analyzer, rather than 1kW RF power. Warranty is void
if you break your JUMA PA1000 amplifier with any antenna tuner when JUMA PA1000 amplifier in OPER state.
Precautions!
JUMA PA1000 has been designed for SSB and CW operation. It is not designed for 100 % duty cycle key-down
operation which is likely to happen in FM, AM, RTTY and digital modes. PA1000 will go to temperature protection
during long key-down periods. Avoid long key-down periods by following the temperature indication.
If the antenna is not properly matched you may not get full power output. SWR better than 1:1.5 is recommended. If
the SWR is approaching 1:2 you may need to lower the amplifier gain or reduce drive level.

Features
JUMA PA1000 is a very light weight solid state 1 kW
linear amplifier for HF and 6 meter bands. JUMA
PA1000 is using a most modern LDMOS transistor in
the RF amplifier. The RF matching is based on novel
design which provides very good efficiency. The power
supply is also latest technology, a light weight
resonance power supply. JUMA PA1000 accepts band
data from popular transceivers. It supports parallel
BCD, serial band data and analog band voltage. The
band can also be selected manually.
• Nominal output power 1000 W PEP
JUMA PA1000 is fully protected against excessive SWR,
over current and over temperature. It withstands
wrong antennas, accidental open or short circuit in the
RF output. The SWR protection is based on reverse RF
power coming back from antenna. Thus if your antenna
SWR is too high you can continue working by lowering
the power.
• Input power: Adjustable gain for 5 W...25 W drive
• Input SWR better than 1 : 1.3 on all bands
• Mains input 230 VAC or 115 VAC
• LCD display for band, gain, SWR, voltage, current and
temperature
• LED bar display for forward and reverse RF power
• SWR, over current and over temperature protection
• Temperature controlled user adjustable proportional
fan speed
• Low fan noise 40dB(A) in stand-by and 55dB(A) at
max fan speed
• Auto band or manual band selection
Simple user interface
JUMA PA1000 is easy to use. There are only the
necessary push buttons in the front panel. The LCD
indicates the essential information, the LED bar shows
the output power and reverse power. OPER, AUTO
band and protection are indicated by their own LEDs.
Rear panel has mains connector, TRX connector, ANT
connector, PTT input and band data input. Firmware
update is easy with a built in boot loader and with a PC.

attenuator. The gain can be set from G1 to G8 with a
step of 1dB. Always start with G1 which is the lowest
gain by monitoring the LED bar power indicator. The
gain setting is individual for each band. PA1000 will
remember the gain settings. Note. EXCITER MAX PWR
setting may limit the max gain setting.
Fan control adjustment. The fan will run with maximum
RPM at the selected final transistor case temperature.
In heavy use you can lower this setting for proactive
cooling. In light use you can increase the setting.
Note. The temperature reading is indicating the final

The power supply may disturb reception at some
specific frequency. In this case you can activate PSU
noise shift. It is lowering the power supply voltage by
few volts during reception and thus shifting the
interference away from the receive frequency.

LED Bar Power Indicator
The LED bar RF power indicator gives a real time view of forward and reverse power. The LED bar hold time (100ms)
and the decay speed (200W/100ms) can be adjusted in the service page if desired.
Protection indicators
Band selection buttons
The protection is implemented in the hardware and
therefore it is independent of the software latency and
operation. When a protections situation is detected
JUMA PA1000 will go to stand-by state.
Push AUTO button for automatic band selection. Green
LED will be ON and the main display is showing the
band. If a valid band data is not available the main
display is showing “?? MHz” and PA1000 will not
operate. In this case check band data cable, band data
setting and the baud rate setting of the COM1.
SWR PROTECTION LED will be lit if the reverse power
limit is exceeded. In this case check antenna, reduce
PA1000 gain or reduce exciter drive.
OVER CURRENT LED will be lit if the final transistor
current limit is exceeded. In this case reduce gain or
reduce drive. You can monitor the current in the LCD.
Nominal current for full power is approximately 24A.
OVER TEMPERATURE LED will be lit if the transistor
temperature is exceeded. In this case reduce power.
Over temperature led will go off when the temperature
has fallen below the threshold level. However amplifier
will stay in STBY state.
Manual band selection is made by pushing
buttons.
and
In manual band selection there is a special “AllMHz”
band which indicates that the final low-pass filters are
bypassed. Do not transmit with “AllMHz” selection
without external low-pass filter because the harmonics
are not filtered.
JUMA PA1000 saves the band selection mode for the
next power-up.
After you have checked the protection situation clear it
by pushing the OPER button.
OPER / STBY button
Simply push OPER/STBY button to switch between operate and standby state. LED is ON in operate-state. In start-up
the default state is STBY. This can be modified in the service pages so that PA1000 will memorize OPER/STBY state for
the next start-up.

This connector is a multi-use serial com for RS232, CI-V
and serial TTL. Tip is RXD and ring is TXD. In CI-V tip and
ring must be connected together in the PA1000 end of
the cable.
AC Power Entry Module
BCD code 0000 as an input bypasses the low-pass filters
and the display indicates “AllMHz”.
All other input codes (1011 ... 1111) are not valid and
they are indicated as “?? MHz”. In that case PA1000
will not transmit.
Tip. JUMA PA1000 converts serial, voltage or manual
band data to BCD output on the four BCD lines in D9
connector. This BCD output can be used to control
antennas or other equipment. The output is 0V/+5V
with an output impedance of 1kΩ. Thus the BCD output
signals must be buffered e.g. with a BCD to Decimal
decoder IC. If a valid band data is not available PA1000
will output BCD code 1111. If “AllMHz” is manually
selected PA1000 will send BCD code 0000.

Note1.
Icom band voltage is not supporting 50 MHz and WARC bands but 10 MHz is defined as 0 V. Zero voltage is
not a proper level to verify valid band data and thus JUMA PA1000 needs 0.1 V to 1 .0 V for 10 MHz
selection. 50 MHz is unofficially selected at voltage 1.0 V to 2.0 V.
Note2.
Some Icom transceivers need a modification to activate band voltage output. See your Icom manual.
