The amp’s manual band switches may be used to directly change bands on the K3S. Also, the K3S can even select per-band amplifier drive levels automatically when the amp is placed into operate mode, so you’ll rarely need to adjust power output. But the KPA500 is not just limited to use with the K3S – it is fully compatible with most radios. (Only amplifier keying (PTT) and RF are required for operation including instant RF frequency sensing, fully automatic band switching.)\u003c\/p\u003e\u003cp\u003e\u003cem\u003e\u003cstrong\u003eKPA500 Features:\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e500W, Compact, Solid State FET amplifier for 160-6 m\u003c\/li\u003e\n\u003cli\u003eWorks and auto band selects with any radio that provides Key-Out and RF signals.\u003c\/li\u003e\n\u003cli\u003eExactly the same size as the K3S\u003c\/li\u003e\n\u003cli\u003e26 lbs, 12 kg\u003c\/li\u003e\n\u003cli\u003eInternal low noise linear power supply: 100-120, 200-240 VAC, 50\/60 Hz operation\u003c\/li\u003e\n\u003cli\u003eInstant-on operation\u003c\/li\u003e\n\u003cli\u003eRugged, conservative design with smart soft and hard fault detection\u003c\/li\u003e\n\u003cli\u003eIntelligently reduces power by 2.5 dB temporarily when presented with input overdrive or a high SWR, allowing you to quickly reduce your drive to compensate without dropping the amplifier off-line.
