The Whispering Giant August 2nd, 2012
We are now building the 500W Elecraft KPA500 Solid State linear amplifier. Almost unbelievably it is only 4 inches high and about 11 inches wide. This linear amplifier delivers 500+ Watts out – even on PSK31 and RTTY. Switch it on and you hear silence. Press the PTT button on your rig and you hear silence, There is no switching noise whatsoever and the KPA500 can easily follow 40wpm full QSK. There is a fan that is thermally controlled, but you hardly ever hear it come on unless the room is really warm unless you are operating extensively. Drive needed is around 40W for full output. It has a silent analogue built in power supply and two large bar graph meters show power out (inc PEP) and VSWR. There is extensive protection against overdrive and high VSWR. A separate LCD display shows voltage, power out in 1 Watt steps and other operational information. There is even an RS232 on the rear for firmware updates. And it is not necessary to be a K3 owner to enjoy this masterpiece of engineering – it will work with any transceiver that has an external PTT to earth line.
This amplifier is normally available from stock.
