Sorry but just checking - are you licenced for those frequencies you are trying to use? Those frequencies are the default frequencies that come programmed into your radio from the factory. I am sure you know they are NOT LEGAL for use in most places in the world.
Depending on where you live of course, if you are simply using the default frequencies in countries where they are not legal, you may be potentially stepping on the frequencies used by licenced businesses or public service agencies in your area.
Also, those frequencies have been mandated as narrow band only for many years in most countries.
Those radios are licenced for amateur (ham) bands only, so if you are trying to use them as walkie talkies, they are the completely wrong radios. As this is not a forum to give advice on illegal usage, I would suggest returning those radios and using ones legal for use in your country or if you have a ham licence, sticking to the amateur frequencies. The licenced users in your area will thank you!
Not your fault if you are new to radios. Those radios may come with random frequencies programmed into them from the factory in China, but that does not mean they are legal to use in most countries, so please stop using wide band and stop using them on frequencies you may not be licenced to use.
Otherwise, the great folks in this forum would be glad to help. We just can’t discuss any illegal usage issues, as I am sure you can understand.
