The modulation dissipates in proportion with the carrier to a max length of 18kHZ reaching to around 11952KHz. The spectrum analyzer shows that the LSB side has less modulation than he USB part Today the signal 25/9 1z+ is centered on 11936.159 kHz. It is highly variable to a range of ±100HZ More zoom could help but the Here is the waveform as tested in an audio program : 13 HZ for the marked 1 second! I posted this info also on the page https://zachs-radiopage.blogspot.com/2024/09/comenting-on-problem-happened-in-sanna.html and hope laeter to add more info if possible _ Hard-Core-DX mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/ _______________________________________________ THE INFORMATION IN THIS ARTICLE IS FREE.
