Moshe Margolese 28/08/2020 - 01:30

How do i download the program? I can’t find where to access it

I bought 6 Walkie Talkies Retevis22 with charging base. Everything I saw was “charge & play”. They are charged, same channel and yet they won’t transmit to each other.
And if they have to be programmed why the heck don’t you charge more and add the stinking cable?
I was excepting to use these the day after receiving.

Cherry 06/01/2021 - 14:02

we are so sorry for this, would you please offer your ORDER ID and which platform you ordered?
then the corresponding sales will contact with you

Jackie 02/03/2020 - 10:43

My church security group purchased 10 Retevis radios about a year ago. I recently purchased two and they will not work with the others. We have the same channel. What can I do? I don’t really want to return them.

Cherry 02/03/2020 - 11:56

hi, would you please tell me your radio’s model? Have you programmed them before?
If you know how to program, would you please send me your radio’s settings?
the way to get your radio’s setting:
1, use the programming cable to connect the radio and computer
2, open the radio’s software, choose the right port, click read from radio, to get the radio’s setting.
3, save it as the file.

then send the file to me, I will check it for you!
My email: partner@retevis.com

Is the model RT22 compatible with model BL22? Even on the same channels i cant get the radios to communicate?

John Radon 27/12/2019 - 01:42

Hello helpdesk,
can you please let me know if programming RT-22 is possible when using the prog-cable for Baofeng UV-5R ?
thanks in advance for your answer !



Cherry 27/12/2019 - 08:37

hi, they two models RT22 and baofeng UV5R can use the same programming cable!

Rod 03/01/2020 - 01:06

I bought (10) that said they could remote alarm and they did not work with my current set. Then I bought 6 more in the charging pack thinking they might work. They receive the alarm signal from the other radios but they won’t transmit an alarm. I have already programmed them successfully to transmit an alarm and neither alarm functions connect to the other radio. This should work.

Cherry 03/01/2020 - 13:40

Hi,we are so sorry, RT22 don’t have the alarm function.If you want to use the remote alarm function, you can consider the model RT21.

CAVERN is the “Cobb Area Volunteer Emergency Radio Network”, a public safety project from our nonprofit and the local town council. We’d be very pleased to hear your feedback on our nonprofit’s website at “CAVERN.mobi”.

We’re using Retevis RT22’s as one of our two basic radios (the other is a BTECH GMRS-V1). We have a few volunteers who have learned to program the RT22 and have been very impressed by some of the things we can do with them. Some of our FCC-licensed users have found that they can effectively turn them into 2W GMRS radios, and we can set them up to interoperate with our Repeater.

If you have a chance to look at our harmless little website, please do let us know what you think! : )

Cherry 23/03/2020 - 17:32

would you please sennd us your website?
I will check it soon, and if any question, please contact with us.

hola ! buenas tardes

agradeceria mucho !!

Cherry 19/05/2020 - 16:54

Hi, you can choose 5 radios in channel 1, and other 5 radios in different channels, it will be solve your question.

Chris 30/05/2020 - 23:14

How come I am able to transmit from the RT22 to different radios but not the other way around? I don’t have windows, so I can’t program them chirp does not work either. What can I do?

Cherry 02/06/2020 - 08:38

sorry, now our software only support the windows, and if you want to transmit RT22 to other radios, just make sure the settings are same!
And now RT22 is the license-free radio, so the settings will be same as the FRS or PMR446 frequency.

Jason 10/06/2020 - 22:41

I dont see the RT22 software on your website. I need a link to the software.

Jeff 18/08/2020 - 03:49

Can you tell me if the Rt22 radios are compatible with the H777 radios?

James 18/08/2020 - 09:20

Hello! Yes, they can. You need to set the DCS/CTCSS and frequency same!

Maurcio Guzman 21/09/2020 - 04:18

hola buenas Tardes hace unos dias compre unos RT22 porque me gustaron pero la frecuencia no funciona con las versiones anteriores como ser el Retevis H-777 ya que compre los RT22 por su tamaño que me encantan, y como hago para que funcionen con el modelo H-777 les agradecere su amable ayuda..

James 21/09/2020 - 14:54

Hello! do you have a programming cable? https://www.retevis.com/2-pin-programming-cable-for-retevis-h777/

Vincenzo De Luca 30/09/2020 - 01:35

Hello helpdesk,
my company bought 6 RT22 with prog-cable, on 1 channel we want change the frequency , because we want use them with the Motorola radio we already have, so the problem i am having when i read from the radio i get a password in “R/W Password”, i would like to change the frequency but i cannot, any suggestion why?, wish i can add a screenshot , please let me know, thank you.

James 06/10/2020 - 15:48

Hi, dear, for the password, please have a try to skip that step. And for license-free radio, the frequency can not be changed, please have a try to change the Motorola frequency same. Thank you very much and have a nice day!

Mark 13/10/2020 - 13:56

I love this radio, but I just lost the button below the push to talk button. The one for turning on the light. How would I ever get a replacement button. I thought I had the radio in my coat pocket, but when I took it out the button was missing. Is there any way of getting a part replaced?

James 14/10/2020 - 11:18

Hi, dear, our customer service will contact you as soon as possible!

Brian Brown 15/10/2020 - 00:23

We purchase qty6 RT27 Radios and programming cable so that we could have them work with qty 6 RT21 radios, when we open the software and select “read radio” we get error “communication false”
We have verified in device manager that the “Prolific USB to Serial com3” is working, shows up when radio is plugged in, using software “RT278-22CH”
Need help, also tried to program the RT21 radios with no luck, get same error “communication false”

Michiel 04/11/2020 - 00:13

Hi, i have 4 pieces RT22 radio’s and your programming software. Serial connection to radio is working fine and i can download settings from radio.

Problem is i cannot change the frequency fields in your programm, they are greyed out, cannot change any frequency.

VOX and ctcss i can change. The box of the radio’s is mentioning “Frequency: FRS”

How can i change the frequencies? Thanks!

James 05/11/2020 - 16:21

Hi, dear, very sorry for the delay! I will send you a file about RT22, please have a try.

Jay 11/11/2020 - 08:21

I have same issue as Michiel from Nov 4, 2020 above.

James 12/11/2020 - 16:42

Hi, dear, for license-free radio, the frequency can not be changed, could you please tell us the reason? Thank you so much and have a nice day!

Jay 13/11/2020 - 01:42

Hi James.
So the RT22 radios are not programmable?
How do I know if they are “license-free”?

James 13/11/2020 - 16:41

Hi, dear, the software on the official website can not change the frequency in the software? I will send you a file, please have a try.

Michiel 14/11/2020 - 18:29

Hi James,

Can you send me this files again as well? The last file you sent me would not extract.

Im am not using a usb to serial adapter, just straight connection to the pc’s comport, i am sure this comport and cable is working as i can program other radio’s with it as well.

Just need the correct software to change the license free radio frequencies. (I am a licensed hamradio operator, if needed i can send a copy of my license, see my mail address for callsign)) At the moment i have 4 useless radio’s because i cannot use ham frequencies, when i ordered these radio’s i was under the impression i could change the frequencies using either the Retevis software or Chirp software, but both of them are not working. (Retevis software can read from radio, but not write new frequencies to radio)

Thank you so much!

Michiel 21/11/2020 - 15:37

Hi James,

Do you monitor the inbox of partner@retevis.com? At Wednesday the 18th I sent you a reply on the file you sent me. (pd0**x@quicknet.nl)
The file unzips, but won’t install due to a extraction error.

I received this file two times already but both times the same problem. Tried it on 3 different computers.


Bill 13/12/2020 - 04:02

I am having the same problem as Jay in that the software will not allow me to change the frequency on any of the channels. Can you send me the software that will work?

Cherry 14/12/2020 - 10:15

hi, RT22 is the license-free radio, so you can not change the frequency

Chad Dawson 19/02/2021 - 09:27

I have multiple rt22s radios that are not on same freq as others, I need to be able to write and update the channels, can’t do it with the software you have online. I also have a 777 that needs to talk to the radios and can not write freq to it as well.

Chad Dawson 19/02/2021 - 12:06

I need the software to get all of my radios talking, I don’t see the point in buying a programming cable or the radios if they can’t work together. Very misleading sales on Amazon. I can just return all the radios and charging bases for a refund.

I manage 6 locations with about 250 radios that I will need refunded.

rt22 rt22s hs777 rt95 base mobile(that wont even get past the lights turning on) and a few rt1’s


Cherry 19/02/2021 - 14:07

Hi, if you want to let all the walkie talkies talk with each other, you need to program them with the same settings. Like You choose channel1 to talk with others, so you need to make sure your channel 1 settings same as as the other radios.
So if you want to program them, you need the programming cable.

Jeff 27/02/2021 - 16:04

Hi, my RT22 radios do not connect to the programming software, I select the correct com port but it does not save it and says cannot connect. When I do the same with my RT24 radios, they remember the com port and they connect OK. I am using WIndows 10. Please can you help.

Cherry 27/02/2021 - 17:13

hi, would you please offer your order ID and platform you ordered? then the corresponding sales will contact with you by email.

Michał Starzecki 12/03/2021 - 03:33

Good morning
I have been using 4 retevis rt622 for 2 years, this year I have bought another two but I cannot program the same frequencies as in previous models from the previous 2 years. A year ago I saved my private frequencies in a .dat file. Currently I cannot open this file. Please help.

Gavin Marsh 12/04/2021 - 22:37

hi trying to program my rt22 radios however the rx and tx freq(mhz) are greyed out and unable to change the values

Jackson Barrett 20/05/2021 - 19:17

My RT22 programming software will say “Can’t connect to radio”, and it’s been the case with different radios and two different programming cables. I’ve tried every combination of plugging in and powering on and etc. with no results. Even my USB drivers are up to date. Any assistance?

Johan De La Mota 12/06/2021 - 05:46

Good afternoon
I have 6 radios RT 22 and recently bought the RT86, I need them to have the same frequency since they do not have it, what can I do?

Cherry 16/06/2021 - 09:15

hi, you can program your RT86 with the same frequencies as the Model RT22

Hola! Al usar el cable de programación y el programa correspondiente con mi RT622, el walkie emite un sonido continuo y los botones no funcionan. ¿Como puedo solucionarlo?

David 25/11/2022 - 05:45

I just bought 40 pieces of RT622 PMR446 radios and I would like to modify the RX frequency range for each chanel to match with my current radios fleet.
I use the software with the right drivers, I succeed in reading the radio but I can’t write another RX freq (it is blocked).

Can you help me please ?
(If no I will have to resend it)

Cherry 30/11/2022 - 10:28

we are so sorry, the model RT622 is a license-free radio, with fixed PMR446 band frequencies, so you can not change the frequencies by the software!
Here I suggest you contact your seller to check if there is any other version software or not.


Constantinus 05/08/2023 - 04:52

Hello, can the RT22 (not RT622) be programmed with PMR446 frequencies? Thank you.

Cherry 07/08/2023 - 13:45

sorry, RT22 is the license-free FRS band radio

ron 18/09/2023 - 02:26

How do you isolate frequencies so you do not get outside interference.
