| capacitor value tolerance in Kit Radio Pixie 40m cw qrp |
| (1/2) > >> |
| vinlove:
I am building Pixie 40m CW QRP kit from eBay. This kit was bought about 3-4 year ago, but was left in the drawer, and had been forgotten all this time. I found it a few days ago while clearing out, and I thought will have a go building it. I soldered all the resistors on the board, and now its time to put on the capacitors. The capacitor value for C1, C10 on the paper is 0.1uF (104). But when I checked them with my DMM, their value is 65 pF. I would think it is 0.065uF? which is about 35-40% off from the spec.? Are these within the usable tolerance, or these caps have gone off? Thanks. |

Check your build, post a schematic or something |

On my sheet, both C1 and C10 is 0.1 uF (104). |

Both C1 and C10 are not critical, 0.1u (or 100n) would be fine in the schematic floobydust posted. But get your units correct: 65p is 0.065n = 0.000065u My guess is that you are not measuring correctly, can you post a picture of the caps? |

It must be 65nP, not pF. I will check it again and update later. |
