Hi guys .I have purchased a sm4450sc from the us with a 93C56 eprom.I have
programmed the eprom with the sm4000 programer (sm4450-ex) with a ctcss
channel.The squelch is operating ok but with the ctcss it isn't muting the
audio.When a non-ctcss signal is applied the audio still comes through .When
a ctcss signal is applied the call light comes on but the audio doesn't
mute when its removed .Link 1 and 2 have been linked as per manual. can
anyone suggest any more I need to check .
Thank You,
