Continuous Tone Coded Squelch System. Some simply remove the CTCSS encode tone while keeping the transmitter keyed for as much as 500 milliseconds, so the receiver's CTCSS decoder squelches the audio circuit, due to loss of tone, before the RF carrier is lost, thus you don't hear the squelch noise burst. As for the tone generator, I'm planning on using an old laptop computer and "nch tonegen", which is a software program that can generate an arbitrary sinewave signal. When the receiver (repeater) hears the required tone, the squelch opens.
