Links(Edit)

• KU4QO's Guide and Elmer101 - Pages like these are the very heartbeat of what makes me love amateur radio.
• Reviews
• Enhancements - Full 5W, Full 40m/CW range, RIT, and Freq display (though I want audio morse output).
• Schematic PDF - This and the next are extracts from K6QO's doc for easy printing.
• Block Diagram PDF
• Component Dictionary(!)

• NE612A - The mixer chips, "Double-balanced mixer and oscillator"
• Elmer 101 on NE612
• NE5532 - OpAmp Chip
• 2n4401 - The transistors
• LM78LXX - The Voltage Regulator

Goals(Edit)

• I want to understand as much of it as possible (for debugging, education, and expansion). It's OK if it's big and complicated as long as the design is componentized and well-explained.
• CW Only (for now)
• Monoband is fine (for now)
• N6QE post (on eHam.net) ups direct conversion and downs AGC. I like it.

Honorable mention(Edit)

• This Norcal SMK-1 really nails it. I like the built-in keyer addition, too.
• The KK7B Binaural I-Q Receiver looks fascinating (great use of stereo sound).
