macro to control KPA500

My abject apologies if this has been posted before, but.....can I
create a K3 macro to toggle OPER/STDBY on my KPA500?

No, I don't believe so. The only data that's passed from the K3 to the
KPA500 is the band-data. The AUXBUS carries status back from the
KPA500 to K3, but only in that direction (AFAIK).

Re: macro to control KPA500

Thanks to all who kindly replied to my query. I am completely
convinced that it can't be done.

As I said to Dick Dievendorff, I was hoping to save a few hundred
gram-centimeters of work per day, maybe even more on a busy day. Now
that hope is gone, and I have expended even more by writing the
original query and this email; that's energy I'll never get back. Such
is life.

73,
Tony KT0NY

Re: macro to control KPA500

If you measure the hand motion required in furlongs/fortnight, it's a very small
number...

Re: macro to control KPA500

But that would be a rate and it might be pretty big :-)

Re: macro to control KPA500

Perhaps it is measured in milliAubs. Prizes to the first person to
identify where this unit is first mentioned! :-)

Re: macro to control KPA500

First used in an email from KL7CC to Elecraft users. This has to be the
first use of the term because GOOGLE never heard of it ;o[

Sorry, wrong answer! HONK!! Try again. And, using Google is
cheating. Shame shame.

Macro to control KPA500

In reply to this post by Tony Estep

Here is how I toggle KPA500 power from the K3 front panel. I have used it
for a couple of months on my remote station that is controlled by a
prototype K3/0 terminal. It consists of a K3 macro and an additional wire in
the AUX cable between the K3 and the KPA500. This simple control is all that
is really necessary for remotely operating the amp, as it works along with
the AuxBus communications to both enable/disable the amp and also report
what the amp is doing. Amplifier status (power ON, OPER mode, power OFF), as
well as any faults that occur are reported via AuxBus and show up on the
K3's VFO B screen. Even **remotely** on the K3/0!

When you use the KPA500's PWR ON = OPER command to immediately enable
OPERate mode when power is turned ON, switching power has basically the same
effect as toggling between OPER or STBY mode. The main difference is that
instead of being powered ON in standby mode, the amp turns off. Since the
MOSFETs have no filaments to wear during power cycling, this does not
present a problem.

If the amp faults, a message appears on the controlling K3's VFO B display.
Press the macro key once to turn OFF the amp, then again to turn it back on.
(Then turn down the drive power a watt or two so it doesn't happen again!)

Implementation requires two steps.

1) Add a wire to the aux cable connecting DIGOUT1 on the K3 ACC jack to
POWER ON/OFF (Pin 8) on the KPA500 AUX connector.

2) With K3 Utility, program this macro into a K3 function key. (I used PF2,
but any should work).

MN019;MP001;MN255;MN019;MP000;MN255

This macro turns ON DIGOUT1, waits, then turns OFF DIGOUT1. This is
functionally identical to momentarily pressing the KPA500's front panel
power button.

Since this is the first K3 macro I have written, and since it worked the
first time, I did not bother to optimize it to use the minimum reliable wait
times. It is fast enough for my purposes, but you may want to reduce
(eliminate?) the waits.

Known Problem:
DIGOUT1 is used by the PR6 6-meter preamplifier to turn it on and off. I
have the PR6 and formerly used this function. With the AUX cable modified
the way I describe, each time you QSY to 6m, the amp toggles power. Since
this is annoying, I chose to disconnect the white power control wire on the
PR6 and let it run all the time, instead of only when I am on 6m. Then, I
turned OFF DIGOUT1 on 6m (in the K3 menu). Problem addressed, and as far as
I'm concerned, solved...

The K3+K3/0 twin remote station works great and the KPA500 was added without
requiring yet another serial port to manage and access remotely.
