Review Palstar LA-1K – 1 kW Solid-State LDMOS HF amplifier

“Here’s a full review of the Palstar LA-1K, it’s a 1 kW dual LDMOS solid-state HF linear. It covers from 6 to 160 meters. The LA-1K as RF sensing allowing automatic band switching without having to interface the radio. It has a very nice color display touch screen which includes a power meter and a live SWR meter. It supports up to 3 antennas. Despite a low IMD distortion of -35dB it supports “pure signal” (low distortion) with a dedicated RCA port to connect your SDR. You can update the firmware via the front USB port.”

Price: $3495.95
