Hi Wayne the list,
not sure if this has been suggested before, but it would be really nifty
if when using a KPA-500 together with a K3/100 the power would be
continuously be adjustable from milliwatts up to 500 W.
The firmware would automagically switch the KPA-500 in at power levels
100 W,
*Well if you start dialing up from 5W on the K3 with the KPA-500 in
'Operate' you get a smooth increase of power out from below 100w to
500w...:-)*

*My 2 cents...*

This occurred to me when I was looking at the prototype at Pacificon
last year. It'd be somewhat non-trivial to implement, though ...
there'd either have to be some negotiation between the K3 and the
KPA500 to get the right drive level for the user-requested output, or
a lot of calibration.
Aside from it possibly being nifty, in what real world context would
you find that to be useful?

So you're one of those all knobs to the right types, eh? ;)

Hi,
Why the negative reaction to this suggestion? I think it would be really
useful if I could operate the K3/KPA500 combo as if it was a single
transmitter with power settings from (whatever the lower K3 power is) to the
full 500W and turn the KPA-500 on and off accordingly. The real context is
Actually, if I'm interpreting the messages properly, you will be able
to switch between 500w and 100w just by placing the KPA500 in active
or standby mode ... provided you have the AUXBUX connection in place.
The K3 will notice whether the KPA500 is active or not, and choose a
different output
*Just a couple of minutes with the KPA=500 will show you what drive produces
required output of the amplifier.*
*
*
*I have power on the K3 set to Per Band and normally run 30W drive to get
500W out. Antenna efficiency plays a role here too.*
*
*
*Once I had that measured the rest was simple.*
*

I like Toby's suggestion. I want the K3 and KPA500 to be as tightly
integrated as possible.

No, not at all. I'm simply honestly curious why it would be
advantageous to be able to CONTINUOUSLY adjust power from the milliwatt
to 500 watt level. I just couldn't think of any scenario where that
would be utilitarian. Still can't.

I guess I don't understand this either.
If you want the amp you are requiring more than 100 watts. I would
assume that you can control the output of the amp by turning up or down
the drive from over 100w to the max of 500w. What am I missing? The
amp is going to require a minimum amount of

To me, the point is that the K-Line is an integrated system, not
simply a few standalone units. As such, an improved user interface
would be for the power knob on the K3 to smoothly adjust for the
entire range of the available power as more K-Line units are added to
the system. This would make
Hi Group,
I also agree for a fully integrated system this would be the best way to
have it work.
Since it is software defined system, give it a little time and it will
be there.

Folks, Let's end this thread at this time. There is no need to argue the point
about closed loop 500w power control from the K3 any further.
It certainly is a reasonable request and we will keep it in mind as we move
forward on these products. As we have a lot of competing areas to work on, we

not some value in between save for RTTY or similar.
