[Elecraft] K3: Band outputs to external decoder

[Andy Faber]

Ralph,
I use a top ten Yaesu decoder without modification with my K3 and it works 
fine.  The TT box has pull-up resistors already, so you don't have to worry 
about that.  The only tricky part is figuring out the pin numbering on the 
DB15 on the back of the K3.  I had to use alligator clip leads to get it 
right, then wired up a permanent cable.  Also, if you start with a premade 
cable, it needs to have all the pins (which some monitor cables don't).
  GL and 73, andy, ae6y
