The two UV-5R8W that display all 6's in the frequency and locks the radios in the transmit mode unit powered down, upon restating it works fine, unless I try to TX on the duplex off frequency again. All three radios have BFB298 and 210223 firmware display. Chrip display HN5RV01 as the firmware. I am using the radio model UV-5R on the UV-5R+plus and using the BF-F8HP model for the UV-5R8W radios.

The radio has to support the Duplex = "off" feature. It sounds like
your UV-5R8W might not. CHIRP disabled TX by not setting a TX
frequency in the radio. What happens when you program a channel with
no TX frequency using the OEM programming software?
