[Elecraft] Band decoder and Tx Inhibit

[Andrew Faber]

Chris,
 Good luck with it.  I have the TT Decoder powered by an independent 12 volt 
source.  It has internal pull-up resistors, so there appears to be no 
connection needed other than the ones I mentioned.  It took me a bunch of 
trial and error time to figure this out.  Let us know how it works.
  I emailed N3RD a while ago to let them know.  Dave said he had a K3 on 
order, and that they did intend to offer K3 cables.  I made up a "generic" 
cable from my TT DX Doubler to the K3, and that seems to work well also. 
It's nice to use inputs all on the back of the K3, so there are no cables to 
the front panel.  Only issue is that the Mic and Headphone jacks on the back 
are pretty frail and don't make very positive contact sometimes.
  73, andy, ae6y
