Jim -
I do not yet have a KPA500, but did recently set one up for a friend.
Although the standby/operate function is not remembered on a per band
basis, I am not sure why that might be an issue.
If your concern is that you do not want to inadvertently run 500 watts
on 30 meters, the per band
THANKS to each of the kind folks who let me know that KX3 power can go to 10
watts for tuning using CW or FM.
Evidently I had misunderstood some earlier list content about PSK being
limited to 5 watts.
I appreciate the feedback!

The other thing you can do if you have the KPAK3AUX cable installed is to use
the INHIBIT function (if you are not using DIGOUT1 to control a PR6 preamp). In
the KPA menu, set INHIBIT to ENABLE, then in the K3 config menu set DIGOUT1 ON
when you are on 30 meters. The problem with this solution

Jim,
I turn off all the power to the Ham equipment when it is not going to be
used in the next several hours.
I have a single switch for power feeding the equipment.

Another case of YMMV..!! My 75amp, supplying 12 vdc to everything on my
desk, has been turned on for the past 9 1/2 years, with the few exceptions
of when I was attaching leads to my distribution panel. And I live in south

Am I understanding KPA500 specs correctly?It looks like if I were to get a

Be careful. The power is on to the finals even when the K3 is turned
off. Therefore, if the finals short, they can overheat leading to all
sorts of issues. Trust me, I found out the hard way. Mine was drawing
2 amps with the K3 turned off.
I make it a habit now to turn off the power supply
FWIW, I just measured my K3 and it draws 38mA when switched off. Mine is
also older - way back in early production.

My K3 (about 2 years old) is pulling under 5 mA when powered off. I

You would be shocked to find out how much power things can pull. It adds

My electric bill from ComEd in Chicago charges the same rate per kWh
regardless of usage. Adding in all costs, the cost per kWh is 9.3 cents.
Other costs of living here are high, but I guess I can afford to keep the K3

K3 #642
Jim,
Here's one possible explanation:
The external power supply must drop all the way to zero V, as must any all K3
I/O signals. This may have implications for attached equipment.
If there's any residual voltage on the supply or I/O lines, even 1 V, the K3
may not turn off all the way. It
I disconnected everything from my K3 except the power cable and the drain
when off remains at 38mA.
I don't have the time right now to pull the PA module, but that sounds like
the next best possible culprit.
I had never noticed the parasitic drain because my station power supply is
switched

I have a question about the batteries in my KX3.

Not wishing to take this thread too much offf course, but the dollar

Simply follow the set up instructions for each band. I'm awful with
computers/software I got it. I run apx 480-500 on all bands but 30m
where it's set at 200w.
Normal is 100w on 30m rarely I kick the KPA on it remembers its 200w

I'm not trying to reply for David, but we have similar objectives for our KX3.
Using 50-54 MHz as IF for the 2M module is genius in my
thinking. 28-30 MHz too often used as IF for higher bands limits use
to few frequencies. Having the full 2m band is very nice for
multiple uses
