RT22 Some general problems and solutions

 

  1. Why same RT22 walkie-talkies which are bought at different times can’t work together?

A: First of all, the frequency of RT22 has been changed twice in order to meet the requirements of the US license-free walkie-talkie.it was changed from the original 400-480 to 462-467 MHz.

Therefore, the new frequency that causes the customer not to be called  which purchases twice and more.they need to program them to the same frequency and CTCSS to work together.

If the customer does not want to program,it will be told that the modified first channel and the third channel before the change can be directly intercommunication; Secondly, the  frequency and CTCSS should be consistent.

  1. Can RT22 work together with RT27, RT21 or other brands of walkie-talkies?

A: The premise of analog radios intercommunication is the same frequency and CTCSS on the same channel . Therefore, it is necessary to determine whether the two types of radios have coincident frequency bands.If it matches,you can suggest the customer to program them to the frequency and CTCSS on the unified channel. If not, you can’t talk together. However, the first 5 channels of RT22 and RT27, RT21, RT24 and RT7 after the modification are directly interoperable, but can work directly with H-777 on channel 6 and channel 7

    1. hi, RT21 can work with RT22, if you two radios can’t work with each other, please read from your radio to get your radios setting, to check where is the difference?

  1. Is there a fix for the call button? 4 out of the 10 I purchased are starting to be extremely finicky on how you have to press the button to transmit.

  2. Using H-777 and RT-22 on channel 7 no problems. Received 20 RT-22S models and no communication with H-777or RT-22. Transmit with 22S will light the other radios receiving light but no audio. Transmit with 777 or 22 no light or audio on 22S. I have programming cable from 777 and have downloaded the software for all 3 models. Will try that at first opportunity. Hoping someone knows the simple fix to make it quicker and smoother making my superiors happy.

    1. have you checked the three models settings?
      you need to make sure they are the 100% same, with the same channel, each channel with the same frequencies and ctcss/dcs code.
      then they can talk to each other.

  3. Hi I would like to order one of your RT22 radios.
    But I didn’t see how much they are.
    Hope you will contact me and give or send me more information.

    Thank you Westly Balthrop
