Today we take a look at the Xiegu XPA125B QRP Amplifier and Auto Tuner hooked up to the Icom IC-705. This amp will work with a variety of QRP rigs including the new Lab599 TX500, Xiegu G90, Elecraft and Yaesu Rigs. Does it do the thing?
The Xiegu XPA125B (new version) is a 100 watts solid-state linear power amplifier for frequencies from 1.8 to 30Mhz and 50 to 54Mhz, with an integrated antenna tuner and a big and bright display for monitoring the amplifier status. It is equipped with protections: temperature, overcurrent, detection of input and output. It’s perfect for your QRP radio or low power SDR transceiver.

The 2.7 inch large backlit LCD display screen shows input/output power, SWR, voltage, current, temperature, amplifier status as well as warning messages making the operation of this modern amplifier simple and also user friendly. The serial connection allows you to hook it up the computer to update the firmware.
Compatible Models Xiegu: G90, G1M, X5105, X108G
Yaesu: FT-817, FT-818
