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. -

Page 6: Theory Of Operation
OVERVIEW THEORY OF OPERATION The 6M-1K2 designation, indicates the amp works on the 6 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. Because most modern Amateur transceivers have a 50 to 100W output on 6M, the gain of the device must be reduced 15 dB or less per part 97 FCC rules. - Page 7 Various tuning, blocking and bypassing capacitors aid in the balanced tank circuits transition through a coax line to a 50 ohms, unbalanced point. Following the tank circuit is a seven section low pass filter. The filter is followed by a high power vacuum relay, the VSWR bridge and finally the output ‘N’ female connector. 6M-1K2 BLOCK DIAGRAM...

Page 16: Wsjt: What Is It And How Do I Get It
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. WSJT is a FREE program written by Nobel prize winning Physicist Joe Taylor, K1JT. Originally designed for high speed meteor communications (JTM), Joe soon implemented JT65A and JT65B to accommodate the EME crowd of weak signal enthusiasts. - 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”...
