Re: [Flexradio] SSB Voice inversion

Just tuned 3700 - 3750 and heard nothing strange. Inverted speech is a rather primitive method of speech privacy. You can beat the signal with a signal generator and recover the speech quite easily. A more sophisticated method, yet also antiquated to a degree, is splitting

I can clearly hear voices. I copied one guy LSB on 3729.070 and a strong carrier (like AM) on 3729.100 (on my Jupiter). The carriers are overwhelming any SSB that might be in there. There is another AM carrier and music on 3729.600 and I can null out the carrier with AN. There are some AM guys

For those interested, there is a station or stations on 3.728 right now, 0023UTC transmitting with this encoding or whatever it is. I am unable to tune it now. Be patient, as they don't talk that often. I would be very interested to know if anyone can read intelligence in this audio. __

Perhaps this evening you could use PowerSDR's "RECORD" feature to record an I/Q file of some of this, using a 48KHz sample rate so anybody interested could study it with average sound cards. You burn about 20MHz/minute, but you wouldn't need much. Maybe keep file size below 10Megs to make email

Re: [Flexradio] SSB Voice inversion

Voice inversion, to put it real simple, is where the actual waveform of the audio is reversed within the sideband. In other words; on say LSB, normally the low freq audio would be on the very right down to DC, and the high end would be on the left end of the passband. Inverting this would create t

Re: [Flexradio] SSB Voice inversion

Maybe I'm ignorant here, but shifting the filter to the other side of the red line would basically switch from Upper Side Band (USB) to Lower Side Band (LSB) detection. You can certainly transmit in LSB or USB by selecting the appropriate mode. Forgive me if I've missed the boat entirely here.
