Below is an excerpt from a message by Dan, written to the QRP-L mailing list.
I hesitate to quote part of the message. In a nutshell, he was talking about his NC2030 receiver transceiver, which was recently released in a public forum (QRP-L mailing list). Here's the exact quote: --------------------------- As mentioned above, the receiver is a phasing type DC receiver. The detector uses a high performance "Tayloe" quadrature detector to produce the I and Q (in phase and quadrature) audio channels needed to allow the receiver to reject the USB side. I have discovered that I did not actually invent this detector. The detector existed in a more complex form roughly 10 years before I came up with the idea. In essence I came up with a simplification of something that already existed, making it capable of lower noise operation. --------------------------- Hope this helps, I'll happily send the entire message to anyone who is interested in viewing it. Contact me off list. Off the record, I'd like to say that Dan spent a lot of time sending email directly to me regarding the implementation of a QSD based LF receiver and helped me to understand class D/E, also by direct email. He's kind, considerate and patient, a good guy, and one smart cookie! Regards, Art ------------------------ Yahoo! Groups Sponsor --------------------~--> Get fast access to your favorite Yahoo!
