Homebrew and Kit Projects /////////////////////////////////////////// Xtal oscillator issue Posted: 09 Nov 2019 10:04 AM PST https://forums.qrz.com/index.php?thr...-issue.680007/ Hi, Conventional wisdom says that an inductor in series with an xtal will pull it low, while a cap pulls it high. That said, I have found pulling them low is more challenging than high. Putting 2 (or more) xtals in parallel is sometimes tried to increase the pull range. Much depends on the circuit values that are used. Can you post the circuit you are using? Also, do a search on super CXOs for more info. Bob WB0POQ |
