“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.
