This is an issue. If you have a band decoder, want to run the preamp,
the amp, tuner, and say a Microham device. I have used multiple Y
adapters successfully.

Rich,
I assume you also have a KPA500 in the mix.
The problem is not with adding another "Y" cable, but the possibility
that the other device will interfere with the band signalling to the
KPA500.
If that other device has pullup resistors, that can create problems,
especially if the pullups are to some voltage other than 5 volts. You
may have to add isolating diodes to that device (the KPA500 does have
those protection diodes on the band data lines).
If it has no pullup resistors, then it may be OK.

Currently I have a wye cable attached to the accessory jack on the
back of my K3 which in turn is connected to a microham device and the
KAT-500 tuner.
I have a need to supply band data to another device, can I connect
another wye to the current wye so I can connect 3 devices to the
accessory jack?
