Additional Quadra information . . .
According to a phone conversation I had several years ago with Yaesu
Support, the Quadra's INPUT 2 was intended to accommodate a six-meter
exciter, not another HF rig. Because of internal changes made by Yaesu
during final design planning (literally at the last minute) to
incorporate other applications, INPUT 2 does not support the same
features as INPUT 1. However, I have received emails from a few K3
owners saying they indeed HAVE successfully used INPUT 2 with a second
HF transceiver but none have testified to resolving the issues Joe
alludes to below. Neither Tom Hammond nor I pursued further INPUT 2
issues for the simple reason that I had no interest in using it.
Moreover, Elecraft's KPA500 was in the final development stages and I
knew I would be using it with the K3. To my knowledge, Yaesu has never
addressed these INPUT 2 issues and the circuitry remains the same as
originally designed. If someone has information to the contrary, please
let me know.
As for Dick's eyesight problems (join the crowd), I suggest taking a
look at the appropriate Winford Slim Breakout Board
(http://www.winford.com/products/brksd15.php) as an easy alternative to
cabling.

Yes. Note however, there are some issues in using two exciters -
particularly the lack of switching for the TF (tuning) output from
the Quadra. There are a couple modifications on-line that add an
external relay to provide that function.
Also note that Exciter 1 (Band Data 1) and antenna 1 are automatically
selected when the Quadra is off/bypassed. Exciter 2 will have no
antenna and the Inhibit line is forced high (no RF from Exciter 2).
if so, if anyone manufactures the needed cable to go between the K3's
accessory connector and the Quadra's Band Data 2 jack?
Not to my knowledge. Further, do not recall any published info on
wiring such a cable - it was not included in N0SS's work - although
one could derive the information from the Quadra Service Manual or
the general interfacing documentation at VA7OJ/AB4OJ's Quadra web
site.
Yaesu offer the CT-178 Connection cable for connecting the FT3000
to the Quadra. One could modify that cable by replacing the DA15P
on the exciter end with the appropriately wired DE15P. Similarly,
one could modify the Yaesu CT-118 cable for the FT-450/950/1200 and
Quadra by replacing the miniDIN-10 on the transceiver end with the
appropriately wired DE15P.

Hi Guys,
Wondering if anyone has successfully used a K3 to control a Yaesu Quadra
by using the Quadra's Band Data 2 jack? My K3's has been controlling a
Quadra via the Quadra's Band Data 1 and it works well. But I'd like
to have my
2nd K3 control the Quadra via the Quadra's Band Data 2 connector. I'm
wondering if this is possible, and if so, if anyone manufactures the
needed
cable to go between the K3's accessory connector and the Quadra's
Band Data 2
jack? (I've got eye problems and cannot wire small cables)
Thanks & 73,
Dick- K9OM
