  • Page 2: Safety Warnings

    25W. It produces full-rated output of 1000W PEP with low input power, typically around 10W. The PA1000 is engineered to provide reliable use in normal amateur radio operation as rated using SSB and CW modes. A rugged, industrial-grade LDMOS RF power MOSFET is used. These devices have inherent high SWR tolerance but must be protected from overdrive and excessive input power.

  • Page 3: Precautions And Warnings

    This results from the inherent timing of ALC and compression circuits in the transceiver. You will achieve full- rated power output with nominal input power of 10W by selecting a suitable gain setting (G1-G8) in PA1000. In all cases, do not allow exciter drive power to exceed 25 watts.

  • Page 13 FlexRadio 6000 series (two alternatives) 1. Serial Band Data FlexRadio supports Kenwood serial protocol which is compatible with JUMA PA1000. Use an USB/RS232 adapter in FlexRadio and make a Kenwood RS232 serial COM cable found down the pages. Make related settings in FlexRadio and select Kenwood Serial Band data in JUMA PA1000.
  • Page 14 Kenwood transceiver. Kenwood is not sending band data event when the band is changed, it is polled by JUMA PA1000. To speed up the band change set PA1000 Radio Poll Rate to 500ms in the Service pages.
  • Page 15 Note2. In JUMA PA1000 set BAND DATA to Elecraft Serial and set the equal baud rate for both. Note3. Kenwood is not sending band data event, it is polled by JUMA PA1000. To speed up the band change set JUMA PA1000 Radio Poll Rate to 500ms in the Service pages.
  • Page 16 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.
  • Page 17 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 JUMA PA1000. To enter Service Pages keep the PAGE button pressed about 5 seconds until you see text “Service pages selected”.

JUMA COM HUB is powered by the USB cable and you don't need a USB - RS232 converter because that is built in to JUMA COM HUB. We are using FTDI USB chipset. The USB COM driver will be installed automatically when you plug in COM HUB to your PC.
  • Page 23 UHF connectors (SO-239 sockets and PL-259 plugs) are somewhat unreliable. Please use high quality PL-259 plugs with PTFE insulator, preferably crimped models and ensure proper junctions. We recommend to tighten the PL-259 plugs with tongs. JUMA PA1000 User Manual Version 1.64 update 2022-02-15 Page 23 of 23...
