what is it called when 2 way radios make that kersh sound when you stop talking?

Question

you know when you realse the button after your done talking and makes a bleep boop or kersh to let the other person know your done talking.

Answer 1

Squelch.

All radios operate on common frequencies. All those frequencies have all sorts of background static at all times. Your radio will have an adjustable setting where you can mask out that background static to a degree where you don't hear it constantly hissing at you. It's called a squelch. You in effect squelch out the background.

If you set your squelch low, all the static comes through loud and clear....if you set your squelch high, only the most powerful signals will get through. If you set it in the middle, people will get through to you....but just as they finish talking, you'll get a sound of background static just before your radio's squelch setting kicks back in and cuts it back off.

You can think of it in terms of an imaginary door. You're inside a totally silent room but on the other side of the door, there's a really noisy crowd. Someone on the other side of the door will have to push it open to talk to you and then let the door swing back closed when they finish. The squelch sound is the noise of the crowd you hear before the door gets closed.

Does that make any sense?

Answer 2

Kirsh is a 120 proof cherry liqeur.
Static, squelch-noise, etc. Its dead air at begining and ending of transmission.

Answer 3

Not all two way radios do that. It depends on the quality of your equipment, the volume (how high did you crank it up to?), static around you? How many units are using the same frequency? 300?1000? 2?

The equipment original quality is important.

Answer 4

simply put, it is caused by the radio,(regardless of quality,) switching from transmit mode to receive mode
