How to work together with these radios.

The RT21 is FRS, it is compatible with those all radios,it can work directly with RT22 and H-777s when out of the box,because they are both FRS frequencies and the default frequency is the same on channels. so you can talk directly.but RT21 and H-777 need to be programmed to work together.

    what are the differences between the rt 21v and the rt 47v? and do you have any intentions on making a small mobile or base unit for murs
    thank you

  2. “The RT21 is FRS, it is compatible with those all radios,it can work directly with RT22 and H-777s when out of the box” – this is not true!

    The H777S set we bought would ONLY communicate with our RT21 radios on Channels 6 & 7. We tried to program the H777S’s to match, but the CTSS/DCS codes starting with the letter “D” will not communicate between the two radios. We are still troubleshooting.
