Yes, but we don't check it. So, if we *receive* a bad image, we will
calculate the proper checksum of the bad image and then send it to the
radio. The radio would check the checksum, see that it matches, and
accept the image.

If the checksum is wrong, this happens (although it doesn't wipe the
memory, it just resets some things). I've never seen a yaesu do this
because of actual bad contents with a matching checksum though.
