More seriously, mating a connector also has the benefit of sinking some
of the heat in the pins lowering the chances of melting the dielectric.

I've done exactly that for the two K3s and two filter sets in my SO2R
station. You need a properly wired cable between each K3 and the

Brett,
For all of the solutions you list, you will need a band-decoder to take
the band data (Yaesu standard) from the K3 and convert it to contact
closures that will drive any of the filter units you have mentioned. So,
the wiring depends on the band decoder you choose and it's pretty
I ran 2 Dunestar 600s for 3 years with no problems in contest service.
They are very well built, and the support is fine. ICE can be very hard
to get ahold of, but a lot of contesters use the 419B without notable
trouble, so far as I know.
The W3NQN filters that Array Solutions uses are
installed to work with this band decoder.

In addition to the prepackaged solutions one can purchase a set
of individual band filters from Rig Expert or Array Solutions
(or build your own W3NQN design filters from the published data)
and use a pair of double switches (two radio antenna switches)
to select the appropriate filter.
The dual
Ameritron makes an RCS12 control head that I use here. I have about a dozen
of them in use.
It not only is programmable as to the allowed output ports for a radio's
band data input, it also works as an antenna switch controller and will lock
out the wrong antennas on the wrong bands. It
Here is a nice unit from an ex-pat, Bob, big into contesting.

Incidentally, if you fancy making one yourself I have sets of wound toroids.

If you are doing this for an SO2R or multi-transmitter installation and no
two radios never ever need to be on the same band, perhaps you can configure
the switching to use one set of separately enclosed W3NQN filters rather
than a pair of products that has a switch and six filters each.
There's

This is a neat controller. I have a review of it in the Product Reviews
section of my website at www.ad5x.com.
