SSDR 184.108.40.206, Flex-6500:
If I have two slices open in the same band and run the ATU on one, then switch to TX on the other slice, the ATU is disabled. This doesn't allow one to easily tune up off the DX's frequency (for example) and leads to more unnecessary time spent tuning. Solutions could be to allow the ATU to remain engaged on the same band, or in the same band segment, or a specified range of frequencies (e.g. +/- 100 KHz) . I'd lean toward major band segments, although keeping it engaged in the same band is also OK, allowing the user to determine if SWR has risen too much.
