This? http://www.lwca.org/library/articles/w1tag/R75cal.htm Dex Alberto di Bene wrote: I remember reading a few years ago on this group a message saying that if the Loran signals are demodulated with an AM detector, a few lines should result, whose precision is independent from the frequency (in)accuracy of the receiver, but is directly tied to the Loran specs, and could be used to calibrate the frequency display of the receiver. Could please somebody recap that for me ? I am unable to find that message again. What I am observing, receiving the Loran signals at 100 kHz and using an AM demodulator, are a few steady lines, one of which being at 1004.70 Hz, quite stable, even in a 700 µHz bandwidth. What should be its theoretical value, based on what written above ? TNX 73 Alberto I2PHD |
