How are PL tones (CTSS, et.al.) typically removed from the audio of received VHF FM repeater signals?
Is it done with a fixed high-pass filter? Or a notch, when using a transceiver with the PL tone configured correctly? Or dynamically, by assuming any constant low tone detected is hum to be removed by an auto-adaptive notch?
Or is it sometimes not removed by filtering because the tiny speakers on handheld receivers don't have sufficient low frequency response?
