How to zero beat wwv
Web27 apr. 1992 · for a zero Hz audio tone. The IF filters for CW and SSB are all offset from the freq that would give a normal zero Hz tone, and so the selectivity would eliminate the signal you are trying to beat against. Instead the trick of beating 3 signals (BFO, WWV, and the calibrator) to allow the user to do an offset frequency comparison. WebSince the WWV carrier is likely more accurate than any other frequency reference that most hobbiests and hams have in their labs, this is a useful technique. It can be used to check or adjust the 10MHz reference in the counter, if it has one, or can be used to very precisely set the output frequency of a signal generator which can then be used as a test signal for the …

If calibrated to wwv or a similar frequency reference, the carrier will be at 0 Hertz. Keep in mind none of us can hear 0 Hz. When we listen to cw we hear around 700 Hz or whatever is your favorite pitch. When we listen to ssb speech, maybe around 100 to 2400 Hz give or take. 18 kHz off? newcastle nrlwWebPosts: 19020. You can usually zero-beat with WWV by listening to the station's modulated tone and the pulsing of the tone that occurs as you approach the exact frequency. Another method is to watch an S-meter while adjusting frequency you are calibrating, aiming for the slowest "up-down" movement possible.
