Hi All,

I have a a Tokyo High Power 1.1KX amp and would like to know if my K3 SN 2704 has this ALC modification installed already?  Is there a magic place to look this up?

Thanks in advance,

The THP2.5 uses a regular 15-pin D-connector, whereas the K3 uses the 15-pin
HD D-connector.  Nothing special needs to be done, other than finding the
pin outs from the manuals.  The THP 2.5 even has pull-up resistors so early
K3 radios will drive the band data input just fine (NOT the case with the
THP 1.5, where you need the K3 pull-up mod).  If you plan on using ALC, you
do need the K3 negative-going ALC mod if you have an early K3.
