I have an SWL+40 on the way, and I am super-excited.
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 IF-to-AF mixer chip, "Double-balanced mixer and oscillator"
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).
- Also by KK7B: http://www.kangaus.com/microt2.htm
- Popcorn Direct-Conversion Receiver page, short demo video
