The heart of our 2 meter 1K2 is a SINGLE very rugged FET, rated at 1250 Watts of output. This device is rated to handle a 65:1 mismatch—just look at the list of added *protection we have built in!
Designed by Ken Holladay, K6HCP (KLM, Mirage, RF Concepts and now JK RF Designs), the 1K2 amplifier is beautiful in its simplicity. The 1K2 is the smallest 1200W amplifier ever offered. We have supplied OUR “state of the art” amplifier with a built in 92% efficient Powergate 2400W switching supply. The entire 1.2 kW amp weighs in at just under 20 lbs! As an option, we offer the 1K2 without the power supply.
The 1K2 is perfect for DXpeditions and field day operations, and makes a great addition to any home station. We’ve designed the 1K2 specifically for EME (CW and JT65) and Meteor scatter using SSB, CW or JT6M. Two temperature controlled whisper fans cool the finned heat sink and cycle on and off as needed. A third fan cools the tank circuit components. If external preamp and relays are used, the amp supplies 12 VDC and also sequences a N.O. key line.
What a perfect 2M package when combined with our new 2M-HCP low noise preamp (LNA) and any of our cross polarized Yagis like the 2MXP20, 2MXP28 or 2MXP32. M2 also offers the bullet proof HPR-1 high power relay and a full line of low loss phasing lines, power dividers and “H” frames for your next array.
