This is an old revision of the document!
Unfortunately, there are many errors or discrepancies between the various resources available for this project. Eventually, they will all be listed here; if you can then update one of the resources (schematic, PCB layout, assembly directions), please do so and then remove the error from this list.
Forum threads: (extract info from thread, place on this page and remove thread from list:)
| Part | Incorrect | Correct | Remarks |
|---|---|---|---|
| C20 | 160pF, do not place | 390-550pF, placement recommended. | |
| C40 | 68pF | ? | Sirenza datasheets say 1-2pF, not clear if this is an error or not |
| C50 | ? | 1 uF 1206 | |
| C51 | ? | .1 uF 1206 | |
| C52 | ? | 1 uF 1206 | |
| C53 | ? | .1 uF 1206 | |
| C63 | ? | 1pF 0603 | |
| C77 | ? | 4.7uF or 1uF, 0603 | Filter cap; 4.7uF part is difficult to get in 0603, 1uF is ok |
| C80 | 20pF | 22pF | Substitute to save money by combining order with other 22pF caps |
| C81 | 20pF | 22pF | Substitute to save money by combining order with other 22pF caps |
| C83 | ? | .1uF ? | not listed in instructions |
| C84 | ? | .1uF ? | not listed in instructions |
| L5 | ? | 1K resistor | |
| L6 | ? | 1K resistor | |
| R3 | ? | 47K | |
| R4 | ? | 12K | |
| R12 | ? | 100 ohms | not a critical value (instructions say 68 ohms) |
| R13 | 100K | 63K | Value may vary to adjust VCO DC Offset gain |
| R15 | 100K | 33K | Value may vary to adjust VCO DC Offset gain |
| R27 | 0 ohms | ferrite bead |
| R28 | 0 ohms | ferrite bead |
