What is a COR signal?
COR – “Carrier Operated Relay” A relay that is usually derived from the squelch circuit of a receiver signaling the presence of a signal at the receiver. This signal tells the repeater controller when a valid signal is present.
What is Carrier squelch?
A carrier squelch or noise squelch is the most simple variant of all. It operates strictly on the signal strength, such as when a television mutes the audio or blanks the video on “empty” channels, or when a walkie-talkie mutes the audio when no signal is present. In some designs, the squelch threshold is preset.
What is Csq tone?
CSQ literally means “constant squelch”. The idea of the tones is to only ‘open’ your squelch when the programmed tone is received. CSQ just means the squelch is not controlled by the tone.
What is Ste repeater delay?
Repeater STE and RL Menu 36 RP-STE delays the receiver from coming back on (keeps it muted) for up to ~1 second after PTT release; in other words it increases transmit to receive turnaround time.
What is SQL in radio?
In radio terms, squelch is the process of muting a channel when there is nothing on it. Usually, when you are on an open channel with no signal, you will hear the constant hiss of white noise which can be annoying.
What is the best squelch setting?
Ideally, the squelch level should be set just above the background radio noise level or at the point where the desired signal is becoming too noisy to be acceptable. Higher settings of squelch level require higher received signal strength to unmute the receiver.
What is CTCSS and DCS?
CTCSS (Continuous Tone Coded Squelch System) uses continuous tones below 300 Hz whereas DCS (Digital-Coded System) uses digital data or encoded-words which are very unique and all encoded words can be used on the same channel without interference.
What is Tune step in Chirp?
Tune Step. The tuning step used to channelize the receive frequency.
What is Vox on a radio?
VOX, also known as “voice-activated transmission” or “voice-operated exchange,” is a switch that begins transmitting when you start talking, making it hands-free. Unlike the PTT, the VOX microphone is ready to transmit whenever it detects noise over a certain frequency threshold and stops when you finish talking.
