The AMP-1000W power amplifier is a fully automatic wideband unit delivering a peak output power of 1.2 kW. Covering a frequency range of 1.8 MHz to 74 MHz, it provides power amplification for both shortwave and VHF bands.
The AMP-1000W power amplifier is a fully automatic wideband unit delivering a peak output power of 1.2 kW. Covering a frequency range of 1.8 MHz to 74 MHz, it provides power amplification for both shortwave and VHF bands.
Running a built-in Linux OS and compatible with Hamlib, the unit enables automatic band switching for most transceivers on the market via the CAT control protocol. It features comprehensive safety mechanisms including fault diagnosis, VSWR protection and overcurrent protection, with support for both input and output VSWR measurement.
Its 10.1-inch HD touchscreen clearly visualizes all operational parameters and delivers intuitive on-device control. An integrated high-power antenna tuner handles VSWR matching up to a 3:1 ratio. Four antenna output ports are fitted, supporting either custom frequency-based automatic port switching or manual selection.
Additional onboard hardware includes a 100 W 50 Ω dummy load and a 1–4 dB adjustable attenuator. The amplifier also supports remote control over network connection.
