Jim,
OK, I think I understand what you were doing, you were using the Top Ten
decoder to furnish the voltage for the relays in the DX Engineering box.
When I designed my switching network, I built a box with a 12V power supply
and 11 relays. The power supply furnished the voltage for both the RF
switching relays out in the field and the 11 relays to route the proper
polarity outside ( +, -, 0, and AC). The relays only needed to be grounded
to close, so I used the Top Ten decoder outputs for that purpose.
If you are wondering how I switch 11 antennas with only four polarities, the
answer is I run a wire outside to the first relay box (Ameritron RCS-4) and
use the 4 polarities to route the RF out 4 different coax's to additional
relay boxes (the other RCS-4's and 4712's). All those relays are switched
by injecting the control voltage on the coax.
When I bought the Orion, the data jack does the same thing as the output of
the Top Ten decoder, so I didn't need it any more.

Yes, when I was using the Yaseu radios, I had built a box with 11 eleven
relays and a 12 V (actually it is closer to 18 V no load) power supply.

The remote switch needs 12-18V DC to energize the relays. Doesn't the
band
data jack close a contact to ground for the selected band?

Jim,
I am kind of curious as to why you needed the Top Ten band decoder with
the
Orion?
When I had a Yausu FT-1000D and then a Mark V, I also had one of the Top
Ten decoders to do the same thing you were doing. Only difference is I
am
using three Ameritron RCS-4's and two MFJ 4712's spread out rather than
one
(like the DX Engineering unit).
In any case, when I purchased the Orion, I sold the Top Ten unit because
the Orion has the bands already decoded on the Band Data connector, and I
no
longer needed the top ten decoder.

I sold my Orion a couple of years ago but still have the Top Ten Devices
Band Decoder. It was originally a Yaesu band decoder with the source
driver
option, and I added the $35 Orion mod kit and bought a $30 Orion cable
for
it. It works fine (was checked out by N2RD of Top Ten Devices since I
don't
have the Orion). I still have the couple of parts removed in the
conversion, in case you want to convert it back to a Yaesu,
I used it with a DX Engineering remote antenna switch on the tower.
Changing
bands on the radio changes the antenna switch automatically.
Top Ten Devices no longer sells the Orion or the Yaesu-to-Orion mod kit.
My
cost was $155 for the unit, $35 for the mod kit, and $30 for the cable,
for
a total of $220. I'd like to sell the package for $175 plus shipping
from
near Chicago.
