500W, Compact, Solid State FET amplifier for 160-6 m

Works and auto band selects with any radio that provides Key-Out and RF signals.

Exactly the same size as the K3

26 lbs, 12 kg

Internal low noise linear power supply: 100-120, 200-240 VAC, 50/60 Hz operation

Instant-on operation

Rugged, conservative design with smart soft and hard fault detection

Intelligently 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. The amp automatically recovers to full power once the soft fault condition is corrected.

Excessive overdrive or SWR events instantly place the amp safely into protective stand-by

Works with any radio that supplies PTT to Ground & RF

Ultra high speed QSK. Silent, diode switched T/R

Super fast RF sensing band selection. Only PTT and RF required for fully automatic band changing operation.

Can receive band data information from most radios that supply it

Fully remote controllable

Six speed temperature sensing fan

Advanced integration with the K3 using the optional KPAK3AUX cable:

KPA500 band buttons drive the K3 band and drive level

Band data is sent from K3 to KPA500 before TX

PTT included in cable, external PTT cable not required

The K3 senses KPA500 operate/standby state and adjusts drive power between two memorized levels on each band.
