Hi.
With a properly tuned signal on -say lower sideband- ; when upper sideband is selected on the receiver, some (inverted) garbled audio is still detected.
Why is there no silence ?
Is it a flaw in the demodulator circuit design,
or is that the nature of the beast,
or is the received transmitter signal flawed in its SSB modulation,
or ?
Please educate me on how to obtain silence. Just built a circuit that adds a second SSB demodulator from the same 455 KHz IF in a receiver (Kenwood R-1000) to simoultaneously obtain both separate sidebands audio and almost ready to insert such in the receiver circuit.
But think that may not work properly; and before going further into tapping/splitting signals in the receiver circuitry, would prefer opinions. The goal is to obtain the audio from one sideband and silence (or normal atmospheric noise QRN) on the other.
