What is CTCSS?
CTCSS is used to access repeaters and networks, allows multiple users to communicate on the same frequency (channel) without receiving radio traffic from each other, and is employed to improve radio operation in high RF noise, interference and congested areas.
What is cos in radio?
COS – “Carrier Operated Signal”, “Carrier Operated Squelch” or “Carrier Operated Switch” is a relayless version of the COR. It’s a digital signal that switched between two logic levels (usually +5v and ground).
Why do I hear Morse code on ham radio?
In ham radio, Morse code signals are often referred to as CW, which stands for continuous wave. Set the rig to receive Morse code by selecting the CW mode and tuning to a frequency somewhere in the bottom 20 kHz to 30 kHz of an HF band. If your rig has more than one filter, set it to use a wide filter.
