Stewart,
You can make a toggleable macros by SWT/SWH commands that emulate
pressing/holding the switches that normally control the given function. I
don't know what is DIGOUT1 and how is it turned on and off normally, but
TUNE is toggled by SWH16.

Val,
DIGOUT1 is an open collector line that is able to be controlled by the firmware.
It is also used to switch the external 6m pre-amp option.
I know that some of the K3 commands (like TUNE) can be toggled by a macro.
My question was how to implement toggling by a function switch to include

yep, I confused AH with WH, so that does not explain the problems the

Stewart,
What you are asking is not possible in one macro. You could do it with
two macros - one to turn it on and the other to turn it off.

That's what I thought Don.
Unfortunately allocating 2 function switches or a Tap/Hold of 1

So much better if the F/W did it.

It is certainly possible to toggle DIGOUT1 with a macro -
MN019;UP;MN255; will do it. It is also possible to toggle the TUNE

Thanks Ed for unraveling some of the misunderstanding of solar cells and

highly optimistic and sometimes politicized ratings while totally ignoring
system efficiencies and come to any meaningful conclusion.
