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.
JUMA PA1000 overview Features • Nominal output power 1000 W PEP JUMA PA1000 is a very light weight solid state 1 kW linear amplifier for HF and 6 meter bands. JUMA • All HF bands including WARC bands and 50 MHz PA1000 is using a most modern LDMOS transistor in •...

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 Fan control adjustment. The fan will run with maximum remember the gain settings. Note. EXCITER MAX PWR RPM at the selected final transistor case temperature.

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.

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.

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.

Service Pages are intended for advanced use, calibration and special settings. If you are not familiar with the service settings do not change anything and exit Service Pages by switching OFF the PA1000. To enter Service Pages keep the PAGE button pressed about 5 seconds until you see text “Service pages selected”.
Firmware programming JUMA PA1000 firmware is easy to update. The latest firmware is available in JUMA PA1000 site. It is a HEX file with a version identification number (e.g. JUMA_PA1000_v102.hex). You can check your current firmware version in your JUMA PA1000 LCD display during start-up.
