1. Built-in Automatic Antenna Tuner: The automatic antenna tuner and power amplifier unit of XPA125B can be used independently of each other as either an automatic antenna tuner or a separate power amplifier. The tuner handles 14-500 ohm loads in the HF bands 1.8-30 MHz and 6-meter band 50-54 MHz.
2. 100W Power Output: The XPA-125B is the perfect amplifier for QRP radios or SDR transceivers with low power consumption （like a 5-watt transmitter） when 100-watt output is needed. Its maximum power output is 125 watts.
3. Safty & Protection: The XPA125B has a variety of intelligent protection circuits to ensure the safety of the amplifier and connected transceiver. When abnormal operating conditions appear like SWR is too high, too much drive power, or too high temperature, the amplifier enters bypass mode and displays an alarm message.
4. New Enhanced Version: After improving its shape and size from XPA125, it is smaller than the old version and can be worn on a bracelet like a small bag.
5. Large Screen Display: The 2.7 inch large backlit LCD display 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.
6. Note: The XPA125B is with FCC & CE certificates. FCC ID: 2ANLH-XPA125B1
◆ Warranty Note —— We provide a 1 year warranty on the Xiegu XPA125B. As usual, if you modify the radio's hardware, the warranty is void. (The warranty is void right after you remove any part of the radio case without the agreement of our support team.) Note any firmware bugs or any other software-related issues are not under warranty.
◆ Disclaimer: No License is required to purchase this amp, nor to Monitor (listen) to the many Amateur (Ham) Radio frequencies. However, an FCC License is required to Transmit (Talk) on Amateur Radio Frequencies in the USA. Please visit http://wireless.fcc.gov/services/amateur/licensing to learn more.
