[Elecraft] APF Results at an Old Timer's shack

[Greg - AB7R]

I don't see this as something that would be left on ALL the time.  Only used as needed.  It does help make an 
otherwise unworkable station readable for a contact.  Just another tool in the box.  When you don't need it, turn it off.  I have not tried this yet 
but you can probably turn it off with a CAT command in the appropriate logger macro in the same way you CLEAR RIT.  Then just turn it on as needed.
