Page 3: Overview
Now we offer the same high performance in VHF amplifiers. The 6M-1K2 and the 2M-1K2 utilize the new Freescale™ LD MOS FET (MRFE6VP6IK25H), a single device specified to produce 1.25 kW with as little as 3 watts of drive from HF to 600 MHz. This is amazing in itself, but adding its inherent stability driving that power into a 65:1 mismatch is equally incredible. -

OVERVIEW REAR PANEL (shown with optional power supply) 9. Key Jack. Ground to transmit. The total keying current is under 10 mA. 10. RF In. 25-50 W nominal. 11. RF Out. It is strongly recommended that an external wattmeter be connected here. Use .405” or larger diameter, 50 ohm coaxial cable capable of handling full rated output power. -
Page 6: Theory Of Operation
OVERVIEW THEORY OF OPERATION The 2M-1K2 designation, indicates the amp works on the 2 meter Amateur Band and is capable of at least 1.25 kW of RF output. A single MRFE6VP61K25H Freescale™ LDMOSFET solid state device is the heart of the amplifier. - Page 7 OVERVIEW voltage also passes through the transformer. The emitter of the device is grounded to its flange base (header) which in turn is attached to the copper heat spreader. There is a common ground then in the system between the chassis, the PC board and the heat sink system.

Page 16: Wsjt: What Is It And How Do I Get It
ADDENDUM WSJT: What Is It and How Do I Get It? A special EME and weak-signal primer by renowned EME expert Mike Staal, K6MYC. WSJT is a new weak signal mode enhancing communications with signal near or below the audible signal level. The 6M-1K2 amplifier is designed for the 50% duty cycle used in this mode. - Page 17 ADDENDUM WSJT: What Is It and How Do I Get It? (Continued) One last bit of information you will need to get started using EME. Since most signals from the moon are at or below the noise they may not be detectible by the human ear. A chat room has been created to allow you to communicate with others doing EME and find where others are transmitting so you can “listen”...
