How could it be more sensitive with CTCSS? I'm not sure I understand. de N5ZTW
A CTCSS decoder looks for a precise tone frequency in a narrow band, so it's fairly sensitive.?A squelch circuit?looks?for noise (no signal present) and loss of?noise (signal present)?in a much broader band?above the voice passband, so it's not as sensitive. 73, Bob, WA9FBO
