I got this from the "Sprat Pixie File"; it's one variation of the Pixie transceiver. Schematic shows a 60pF (C2) cap switched in when keyed. But... What the is value of the other Colpitts cap (C1)? Is that supposed to be 0.001uF? And why switch the 60pF and not the 1000pF? The 60pF isn't going to produce much of difference when keyed...Going from 1000pF to 1060pF?
