Last night I got a chance to test importing saved .img files from
my Wouxun into an Anytone radio. For the most part it works well. I also tried it reverse. .img from Anytone to Wouxun KGUV6D imported but didn't write the first 5 lines which were all public service. Seems
it didn't understand the duplex settings. I went back to the Anytone, .img made changes in Chirp then imported it back into the Wouxun.
That time it worked. I also uploaded the same .img file to the Anytone and the changes in the settings really didn't matter for those frequencies since I don't transmit on them, tx is actually disabled for all public service.
Se yes this is a good way to share your files back and forth if you have
different radios. You might need to make some changes because of incompatible settings but that's not a big deal.
