    I have purchased 4 RT45p radios and was told by Retevis i was able to use these with our current RT622 radios. Ive tried everything to get these to work together with no luck the software from retevis does not find the rt45p radio either…. please help!!

    1. No programming of RT45P. If you have a programming cable for RT622 radio, you can check the frequencies and CTCSS/DCS codes. Then, you can select the same frequencies and CTCSS/DCS codes on your RT45P radio.
