it say check all connection and try again ... and then i am unable to re-read - / write my radio anymore
radio show UNPROGRAM after programming crashed and no rs232 serial communication to my NX is possible anymore ... ugh

I'd look closely at your cable and your computer comm port settings.

Were you ever able to program these radios with this setup? The "UNPROGRAMMED" on the display is how they ship from the factory when they are brand new.

Which programming software are you using? NX-800/NX-300 use a different programming software from the NX-320

yea thnx for your reply ! i have 2 different prog cable (1 prolific / 1 CH340) i use kpg141D / kpg111D for thoses 2 nx

n yea i am able to read/write untill communication error happens and i loose a radio ... its like i service my NX for a while and someday , CRASH ... and then im unable to read this radio anymore and it show on display UNPROGRAM

the nx800 has 3 serial ports and i am unable to use any of its rs232 data comm ports

i have win11 n win10 on many diff computers , the fatal crash happened on win11 with a ch340 chip rs232 to TTL

Tony, try to firmware update it, see if that restores it, also, did you try the DB25 on the back of the radio to program it?
Most cases, not all, all you need to do is write to it again.

Advise what your out comes is please.
