One correction. The CONFIG:KIO3 setting can change the band
outputs to specify which transverter you are using instead of
which HF/6M band you are using. See page 19 of the manual.
I am using the band outputs as input to a Arduino based homebrew
antenna switch with on problems.

Charles,
There are no CONFIG settings related to the band data outputs.
What are the characteristics of the inputs of your external device?
The K3 band data outputs have pullup resistors to provide +5
volts or zero volts to an external device. If that device
requires +12 volts and zero volts, it will not work.
I might also point out that some early K3s do not have pullup
resistors internally, but provide an open drain output. Those
need external pullup resistors to +5 volts in the external
device or installation on the internal resistors in the K3 -
the internal resistors are documented as part of the K3ALC Mod.
Do you have any other device (such an the KPA500 or other
amplifier) connected which also wants to use the band data
lines. That can complicate the addition of another device on
the band data lines.

hello all and merry xmas!
For various reasons I need to interface an external device with Band Data
from my k3-100 via the ACC port. The cable I have is sending the correct
pin signals to the device, which expects Yaesu Band Data compatible
protocol. AFAIK and can verify on the web Elecraft 0123 band data is the
same as Yaesu ABCD.
But so far no joy at the device.
According the my late-model K3-100 manual (Feb 2015) I have all the
necessary mods from the factory.
I want to verify I have not omitted any CONFIG settings. I have left
KIO3 to the default of normal, tho I tried he others with no success. .
AUTOINF is not relevant as I am not using serial port rig cat, so it is
left at the default of normal.
Have I missed any settings?
tnx in advance
