Not really. At just 1 baud and with questionable reception in many parts of the country, checksum bits aren't the answer. The usual WWVB trick is to collect as many minutes of data as you want in order to increase confidence in your decoded result. It allows you to pull a very weak signal out of the noise. This might be as little as 1 or 2 minutes; or depending on time and location, it might be 5 or 10 or more minutes. With this level of patient oversampling there are a number of software tricks one can employ to pull out an error-free timecode from incredibly weak or noisy signals. /tvb _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
