I have a RT7 model, and I want to change the channels 9 to 16. I write new values to device, but when I read again, my values are lost, and it shows the factory values.
I change the values on channels 9 to 16, but always returns the factory values. This error occurs for all columns on these channels. Another example; I change the scan column to Yes on channels 9 to 16 and when I read the device, it returns this column on these channels is No.
Please, can you help me? Thanks a lot.

Check if you click “write to radio” when you finish the programming.

I purchased the RT-22(set of 4), so that I can use them on the job. We currently use Hytera TC-508U(1); however, there isn’t enough, well many are not working. So, here’s my question, how can I connect my RT-22 to the Hytera?

Please make the two radios with the same frequeucies and CTCSS/DCS, then they can talk with each other!

Hello: we have older H-777 radios and just bought new RT 22 radios. When the H-777’s are programmed on channel 5 to match the values in the RT 22’s channel 5, the audio sounds distorted and robot like. Any thoughts?

Cherry 05/12/2018 - 09:58

Could you please send me the two files for H777 and RT22 By email? Our email is kam@retevis.com
We will test them for you to check the question.

Hello what would be the best frequency to program RT7 radios to be used indoor in a 15 floor concrete building?

Cherry 24/07/2019 - 09:16

Hello, so sorry for the delay reply!
usually use the radio indoor and with the building 15th, There will be interference. We suggest you consider about the repeater.
