The answer is no. It would be a huge safety issue for the KPA to automatically

Check the transceiver. The KPA has constant gain, and nothing that allows it to

If you use a K3, then reconsider your choice to use ALC. It is not recommended,

Let me restate this. The diode needs to "point" at the K3 in order for
the K3 to pull the BCD signal low.
So the bar (cathode) is towards the K3, while the triangle (anode) is

With just a few exceptions (mostly Apple Apps), Mac apps do not have to be
directly in the Applications folder. The solution to your problem is to put the
entire folder containing the P3 Utility into the Applications folder. I
actually have all my Elecraft Utilities in a single folder ins
just fine for
you.
After trying these two things, if you still cannot get things working, let us
know.

As usual, Iain is correct. The KRC2 normally outputs standard BCD (check the
KRC2 manual for details) for the band that is currently selected. The serial
input selection does read Kenwood/Elecraft serial data, outputting it to the
decoder terminals as well as the BCD terminals. It should work qu
closest to the microcontroller.
Floating band inputs (or all 1s) does not cause a band change, so the KPA
simply defers to the RF sense.
As you noted, it works quite well.

Why not just emulate a K2? All you need to do is to issue IF response to the
KRC2 and it will respond the the band/frequency and make alternate selections.
The PC does not need to listed to anything from the KRC2 unless you really want
it to.

bus on the K3/100 and program the
PF1/PF2 keys on the K3 to cause the KRC2 to activate a couple of relays?
If so, where can if find the information to do this?
Thanks & 73,

The KRC2 ACC outputs are very explicitly available through the K3's ACC menu
control. what Craig needs help with is some way to access that control using
macros.
So the question is how to access that menu setting in the K3. Any ideas?

No diodes, no extra connections. Just use he KRC2 utility to change the band
map so that a single output is dedicated to the tribander, and others to the
band pass filter. I do this in my own system - I have one output that selects
my A3, leaving other outputs for other purposes. It is very usef
The Elecraft KRC2 does a great of providing the control signals for the
Dunestar filters. Just connect it to the K3's AUX IO connector, then the
Dunestar inputs to the appropriate KRC2 terminal outputs and you will get
automatic band pass filter switching.

is that even at 38400 bps, we still have to wait for the
processor to write its data. Increasing the data rate would not speed things up.

Download the manual from the Elecraft web site. It has descriptions and
schematics that should help a lot.
Any specific details you’d like to know?
