Eric I wonder if you have a serial/usb-serial link from your K3 to a

Well of course it's a question of convenience. It's neater and more
compact to have the battery inside the K2. Also a major advantage of
the battery for me is that it weights the K2 down on the desktop so it

had is when I forgot t

There is no one 'right way' - My opinion -- If you ever toggle the

slots will be easier to remember - i.e, FL4 is the 400 Hz filter no

The VRFDET is secondary. If the 8R voltage rail is going low, the K2 is
