K3 Aux I/O and Dunestar 600 Bandpass filters

[Ken Adams-2]

I have searched archives galore and cannot find, or do not know how to
search properly for interfacing the K3 to the Dunestar 600 Bandpass
filters.  Has someone built a cable that goes directly from the K3 Aux
I/O port to the Dunestar such that it will automatically switch in the
correct bandpass filter?

Ken,

I looked on the Dunestar website and found that the model 600 needs
decoded band selection.  They mention the Top Ten Band Decoder.
The K3 band data outputs are encoded (see the manual for the encoding
chart), and so you will need some sort of band decoder between your K3
and the Dunestar filter.

I use the same board/circuit I use to drive VHF transverters from my K3 to
drive my Dunestar. The only difference is the K3 menu settings. I wrote it
up at http://g4fre.com/k3vhf.pdf

You'll need a "band decoder". Try a Top Ten Devices Yaesu decoder or a  
Universal Microsystems BCD 10, which is very affordable. These devices  
convert from BCD to a separate wire per band.

Or an Elecraft KRC2 will do the job quite nicely!

Of course the KRC2 will do this! My apologies!

An advantage for using the KRC2 is that it can obtain the band data from
the K3 RS-232 port and one does not have to wire to the 15 pin ACC
connector.
