What is squelch tail eliminate?

What is squelch tail eliminate?

In the commercial world “squelch tail elimination” is done by taking the sub audible tone, and at the instant the microphone unkeys, reverse the phase of the sub audible tone. The receiver senses the phase reversal and mutes the audio before the transmitter stops.

What is Dtmfst on Baofeng?

DTMF. Setting Menu 16 DTMFST to DT-ST or DT+ANI mutes the microphone preventing it from interfering with transmitted DTMF and 1750 Hz burst tones.

What is a repeater tail?

Squelch Tail – The short burst of white noise heard on an FM receiver between the time a signal ceases to be received and the squelch circuit actually mutes the audio output (the speaker audio). This term is often confused with the “carrier delay”, “hang time” or “drop out delay” with respect to a repeater.

What is squelch hysteresis?

Basically, hysteresis prevents weak signals from “popping” the squelch open and closed rapidly, which would be very annoying to the listener. A squelch circuit with hysteresis requires a stronger signal to open the squelch than it does to keep it open.

Can a Baofeng handheld radio hear a squelch tail?

When the transmitting Baofeng un-keys, the receiving baofeng does not hear any squelch tail, and has a smooth un-key. Scenario 2: The Baofeng handheld radio Keys up. A different brand radio is used to receive. When the Baofeng un-keys, the squelch tail is heard through the speaker of the other radio.

How does the BaoFeng UV-5 Squelch Tail Elimination?

Baofeng UV-5 radios can (mostly) eliminate the loud hiss heard at the end of a transmission before the squelch kicks in after the received carrier drops: Menu → 34 STE → ON.

How does a transceiver eliminate squelch tail noise?

Transceiver – Squelch Tail Elimination This function is used eliminate squelch tail noise between UV-5Rs that are communicating directly (no repeater). Reception of a 55 Hz or 134.4 Hz tone burst mutes the audio long enough to prevent hearing any squelch tail noise.

When to use the delay setting on Baofeng?

Controls the PTT-ID delay in milliseconds. Using this setting can compensate for lost or improperly received PTT-IDs when the receiving unit cannot accept them as fast as you are sending. This could be due to distance delays or interference.
