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 |
|---|---|---|
| PA/Filter | 12/4/2008 | Added statement to receiver test to the effect that pins 1 and 5 of J2 must be jumpered (or a PAF board mounted in J2) for the antenna to feed into the RX portion of the transceiver. |
| Local Oscillator | 12/01/2008 | Corrected resistor designation in instructions for installing CMOS jumper. Originally was "...install a jumper wire between the hole of R25..." Changed to "...install a jumper wire between the hole of R43..." TX to George KH6OZ for catching the error |
| BOMs for PAF1, PAF2, PAF3, PAF4 | 11/16/2008 | Fully implemented 11/10/08 changes from 9/16/08 specs:
|
| BOM for PAF-4 , PAF | 11/13/2008 | added capacitor "CA" (22 uF)
to 15 m board's BOM, plus note in PAF build doc to install CA for that board. Tx to Javier KC2QII for catching this. |
| BOM for PAF-3 | 11/07/2008 | Corrected
number of turns in L-201 and L-202 from 13 turns to 14 turns,
bringing them into line with the 16 Sep 2008 Schematic. Also changed
inductance on these coils from .51 uH to .6 uH Finally, changed inductance and windings on L300 and L301 to agree with 16 Sep changes. |
| BOMs for PAF-3 and PAF-4 | 11/07/2008 | Corrected
number of turns in T-201 and T-202 from 5:3 and 3:5, respectively, to 6:3 and 4:5,
bringing them into line with the 16 Sep 2008 Schematic. Thanks to Bill K0AWU for helping catch the error |
| BOMs for PAF-3 and PAF-4 | 11/07/2008 | Corrected
number of turns in T-201 and T-202 from 5:4 and 4"5, respectively, to 5:3 and 3:5. Thanks to Bill K0AWU for helping catch the error |
| PTT and RX Switching | 10/22/2008 | Made corrections to testing sections of both pages, changed PTT testpoints graphic,
modified expected value of "high" measurement from 5 V to 10-12 V,
and modified expected measurement value for RX Switching limited current draw test. Thanks to Oleg Titov for catching the error. |
| RX_Mixer | 10/08/2008 | Added Oleg Titov's photos of completed RX_Mixer (top/bottom sides of board).
Original documentation had failed to capture this stage's completed bpard shots.
Thanks, Oleg, and good luck on your test. Also, thanks for the link to your website. |
| PA/Filter | 9/16/2008 | Added test of forward bias in TX at junction of R204 and R205. Thanks to Eric ZS6BUJ for the tip. |
| PA/Filter | 9/15/2008 | Multiple changes to reflect Tony's 9/14/2008 redesign for PA Filter issues in 80m and last two "bands":
|
| Power Supply | 8/29/2008 |
|
| Home | 8/23/2008 | Added Tony Park's abbreviated "expert builder" instructions to Home page for the experienced builder who prefers an approach that does not involve the staged construction technique in these notes. |
| PAF, PS | 8/16/2008 |
|
| BPFs | 8/12/2008 |
Clarified that wire lengths on bifilar windinges are per secondary, such that the total
wire length required would be 2x the stated length.
.
Thanks to Walt AE8L for recommending this. |
| Multiple | 8/11/2008 | Modified current-limited test to use 100 ohm resistor
and to measure the 5 and 3.3 volt rail voltages when limiting current thusly.
Voltage of around 2 Vdc indicate that there are no shorts on the two rails.
Low current draw when current-limited thusly indicates no shorts on the 12 V power rail. Tx to Alan G4ZFQ! |
| PAF | 8/11/2008 | Extensive changes to RX and TX testing steps |
| RX BPFs | 8/10/2008 | Changed BOM to correct typo on desination of BPF Board for 80/40. Changed continuity test on primary winding of T100 to recognize can't successfully test for continuity through C100 (Thanks to Dick, WB7OND, for catching the error). |
| All pages | 8/7/2008 | Changes each stage's page to place summary build notes immediately after schematic and provide link at end of summary build notes directly to Testing. For those who prefer to do with less detail hand-holding. |
| 12-PAF | 8/7/2008 | Modifications to Build and Test instructions to reflect biuild experience. Addition of non-scope-based RF output test. |
| 12-PAF | 8/5/2008 | rearranged sequence of tasks in inductor section to better conform to Tony's recommended sequencing |
| All pages | 8/4/2008 | Added Summary Build Notes section just after BOM, summarizing the detailed build notes (allows builder to print out just first 1 or 2 pages of a web page after reading details; use as checklist. NOTE: all pages 1-11 are completed. PAF stage (#12) not yet completed. |
| 12-PAF | 8/7/2008 | Modifications to Build and Test instructions to reflect biuild experience. Addition of non-scope-based RF output test. |
