[Elecraft] K3 SUB RX Cancel upon Band Change?

[n6ax at speakeasy.net]

I have a macro assigned to a key to set up sub receiver, split with a 2 kHz
offset for split operation....when I change bands the split is cancelled however
SUB remains on....it is, of course, simply a button tap to turn it off but I
would like the SUB to also turn off on band change....


Probably a menu setting I have wrong....any suggestions appreciated.


Thanks

John
