I have pretty well completed the "Heathkit-like" set of Builder's Notes for the Lite+Xtall V8.3 (LVDS) kit. The notes apply, as well to the CMOS version of the Si570.
The notes permit the builder to tackle the kit, stage-by-stage, beginning with the Power Supply and ending with the completion of the Mixer stage and a completed RX. Each stage is addressed in the following subsections: 1. Schematic (a subset of the overall schematic) 2. Bill of Materials (a subset of the overall BOM) 3. Installation Notes (describing the actual build steps for the stage) 4. Completed Board Views (top and bottom views of the board as of completion of the stage) 5. Tests (tests that can be applied to the stage before moving on to the next stage) For those prefer to build the kit in this step-wise sequence, with intermediate completions and tests as confidence builders, the documentation is available as web pages (and also PDF's) for each stage at the following link: http://www.golddredgervideo.com/wb5rvz/Home.htm (kudos and thanks to Leonard KC0WOX who gave me the idea and the web space for this effort) I used my V8.3 kit as the "guinea pig" for these notes and performed all of the tests indicated in the stage test notes, with the exception of the tests requiring a scope. Between my minimal skills and my dubious equipment, I cannot attest to those scope-based tests. I would very much appreciate feedback, especially from those who have superior skills and equipment to help fill in the incomplete notes on the scope-based tests. There is also a "comments" link on the web pages that you can use to let me know of any errors you may encounter and/or any suggestions for improvement. Please use it. Tx es 73 de robby wb5rvz
