Thanks, Mike. Unfortunately, that means that the inexpensive 1366 x

Fred;
If you mean the KRC2, the high and low side drivers are locked together in
hardware, so no they cannot be separated. With 16 configurable selections, it
meets most folks needs.
This is also a good time to remind folks that the final KRC2 configuration tool
is on the Elecraft web site.

1024 x 768 seems to be the lowest common denominator - almost all
monitors support that resolution. I normally leave my P3 SVGA set for
1024 x 768 just because the text is bigger and it makes the lines fatter
and easier to see.

Thanks Jack. I figured that was the case. What I want(ed) to do is drive
the 6-pack x-bar switch which has a tribander on it so 10-15-20 will be
mapped to the same output PLUS drive a 6-band bandpass filter which
needs to have separate outputs for 10-15-20. Any ideas?
Cheers,
Fred KE7X
Fred,
You can wire OR either the high side or the low side.
If you are running the tribander on the low side, just connect the 10,
15, and 20 outputs together, and drive the bandpass filter from the
separated low side outputs. Swap 'high' and 'low' if required.

Assuming that you've calibrated the P3 per the instructions in the user
manual, try turning off 'Averaging' on the P3. The peaks of the signals
should then be much closer to what the K3 S meter reports.

Hi Ed,
I can load my tri-band quad on 17m or 12m with the K3's ATU, but the signal has

can also tune my 130' CFZ on any band through a heavy duty HB matchbox, but I

I guess not normally but I need to drive two separate devices -- the ant

I had a similar Q. While I do NOT recommend this, the KAT500 can only bring
the 100 meter dipole (EDZ on 80M) to 4.57:1 so I used the internal K3 tuner to
bring it down further (1:1) and gave or a shot on 160M.

Fred,
Your first post indicated that you could drive one from the high side
and the other from the low side. If that is the case, then diodes are
not required. If both must be driven from either the High side or the
Low side, then yes, diodes would be required.

Hi Bruce,
It might suggest that the power supply puts out a lot of RF noise. This
would have little impact on IT equipment, but might make it undesirable to
use near a radio. I would give it a try and see how it works. But before
doing so, I would get out a volt meter and make sure that the
Buddipole is a good antenna but somewhat heavy and not quick to set up
and tune. With the ATU, you can generally set it to a recipe and let
the tuner take care of the rest. I found verticals worked best, all the
horizontal configurations [arms up, out, up and down, V, whatever] are

attach to whatever I can find with bungy cords.
I was thinking of wire antennas to get started.
I chose the tuner over a solution like the Buddipole with that in mind.
I'd put the KX3 in the car, but I like digital modes, but I don't want
to see if the CHP would consider PSK-31 to be texting.
