On a 6600M, is there a way to lock a slice to an antenna?

When you change band it will always use the antenna last used for that band, regardless of slice. So if you use 20M on Slice B with ANT2 then move to 40M, if you go to 20M on Slice A it will be set to ANT2 as this is what it was when last used.

This is a pitiful when trying to do SO2R, that you generally always want Slice A to keep to ANT1 and ANT2 to Slice B.

Various ways round it, I use a program called Flex Butons, so when I change band it sets the band, frequency, antenna, dax channel etc, all so it's always correct on the slice I want.

Think you can do it with profiles but this seems much easier.

Yes when I first got my 6600 it was very frustrating given it's sold as an SO2R radio.

If you have a stream deck you can do the same but assigning multiple functions to a button to activate when you press it.

I find flex buttons better and it can do a whole load more but I mainly use it for band changes. Have set up buttons for SSB, CW and RTTY for Slice A and B so it's used for SO2R.

I found profiles confusing too, this is easier as the little window just sits in my desktop, 1 click and it's done.

Yeah, you will be sat for a while, I have changed layouts a few times until I got to one that worked.

Here is mine, not saying it's right for all but works for me.

Here is an example of one slice so you can see.

If you search the community, Keith has made several posts but his website above links to download and the manual. A great tool.

The problem I’ve experienced with multiple slices stored in a profile is that, after recalling a profile, the slices don’t always get created with the same letters as when they were saved. This becomes a problem (for example) when you save a profile with 4 slices - 2 for FT8 and two for voice. You set up DAX and CAT to attach to particular slice letters and then recall the profile, if the slices come up with different letters it breaks the DAX/CAT setup.
