HF BPF Revisions
Revisions to the Pages/Documentation
This page provides a log of activities in concurrent building, debugging, and documenting the kit, identifying changed web pages and describing the changes/status.
| Page | Revised Date | What Changed |
|---|---|---|
| Home Page | 10/7/2009 | Added link to allow downloading PDF file of these pages. Tx to Craig AB9IV. |
| Transformers | 4/2/2009 | Clarified potential confusion over V9.0 Antenna terminals appearing shorted when BF-BPF is plugged in. |
| Home | 1/16/2009 | Updated links to Tony's shcematics to reflect the 1/12/2009 version (now uploaded to reflector). Corrected incorrect schematic to reflect 1/12/2009 schematic and mods to provide 2 options. |
| Multiple | 1/12/2009 | Added Option 2 for 3.5-30 MHz plus 6m. Changes affected band 1, band 2, BOM |
| Band 1 | 1/12/2009 | Clarified alternative winding instructions for high-number-of-turns coils |
| Bands 3 and 4 | 1/9/2009 | Added completed stage docs |
| Home | 1/2/2009 | Added note that programmatic bandswitching is currently implemented in Winrad and PowerSDR, if not in Rocky. Tx to Cesco HB9TLK |
| Switches | 12/19/2008 | Changed emphasis on testing the switches, establishing preference for a functional test at the end of the transformers stage. |
| Transformers | 12/18/2008 | Completed Transformers Stage and updated page with WIP and completed images. |
| Switches | 12/17/2008 | Updated for completed stage. Modified continuity tests. |
| Busses and Rails | 12/16/2008 | Completed the build of this stage and updated to reflect minor changes in sequencing and measurement values. Added resistance tests pre-ceding power-on tests |
| All | 12/16/2008 | Cleaned up BOM items (markings), resistor values Also published PDF of HF-BPF Kit Component Inventory, uploaded to reflector files folder for V9.0 |
| All | 12/6/2008 | Revised PCB images to agree with 11/30/2008 version of PCB layout. |
| All | 12/2/2008 | Fine-tuning the tests |
| All | 12/1/2008 | Major revision to reflect changes in Schematic V1.3 and new board layouts |
| Multiple | 11/26/2008 | Corrected turn counts and lengths for some of the inductors. Clarified implementation and nature of P102 in the Busses and Rails page. |
| Band2 | 11/25/2008 | Corrected L5 inductance and turn count. TX to Jan G0BBL. Corrected page is Band 2 (4-8MHz BPF) |
| Home | 11/17/2008 | Corrected truth table in Theory of Operation to agree with 11/8/2008 changes. TX to Kurt KC9FOL for catching the typo |
| BOM | 11/9/2008 | Added summary component inventory list to faciliatate counting parts upon BOM inventory. |
| Busses and Rails | 11/8/2008 | Added resistance test to validate proper installation of R3&R4 |
| Switches | 11/8/2008 | Corrected truth tables in tests (middle 2 bands' jumper settings were transposed). Tx to Bob WB7DMX for catching the miscue. |
| All | 11/2/2008 | Published enhanced builders notes (DRAFT) |
