GREAT NEWS! In our ongoing effort to make the PA1000+ even more affordable, we’ve optimized the supply chain, improved production and partnered with top suppliers for high-quality components at better prices than before. Besides that, we are manufacturing our own power supply model for PA1000+.
The JUMA PA1000+ is a high-performance 1kW PEP linear amplifier designed for HF and 6-meter bands. It is delivered fully assembled, tested and calibrated, featuring a lightweight and compact form factor (just 5.5 kg / 12 lbs) along with advanced digital control. Originally developed by the JUMA® Radio Team (OH2NLT & OH7SV), the PA1000+ is now manufactured, assembled, tested, and calibrated by ROWAVES in Sibiu, Romania. All hardware and firmware remain under the copyright of the JUMA Radio Team (www.jumaradio.com). Production is carried out under a commercial license from JUMA Radio (Finland). How to use JUMA PA1000+ remotely? See HERE.
Color options: black (front & rear panels), black case – standard lead time: 3…5 months
*How to order? Mention at checkout “option A, B, C or D”. All have the same price. **Colors of the buttons may vary, based on their availability (black or grey, same finish).
