Interface for the FT-990 (and FT-1000 timeout prob)

[John D. Allen]

There are or were boxes available.  The one I am using is or was sold
as the KIY box, by K1CC.  It works fine with the FT1000.
(KIY means Kenwood, ICOM, Yaesu - the box can work with all three 
brands.)

(Note that early boxes may not work with the FT1000 (and maybe other
FT's??) due to a specification problem of some sort.  (Apparently 
there was an omission to the FT1000 interface spec.)  The fix is a 
pulldown resistor added to the box on the FT1000 send side..

I had the FT1000 radio timeout problem with CT (any version) until
this resistor was added - the problem was that NO data was getting 
back to CT from the radio.  That can easily be checked with any 
scope.
