K3s Power Selection

[Richard-6]

In the Config Menu:

PWR SET
If set to PER-BAND, the power level is saved on each band.
This is especially useful with external amplifiers.

Mine is set to PER-BAND.

If a KPA500 is connected to the K3S via the ACC cable (as mine is),
two sets of per-band power settings are saved: one
for “barefoot” operation, one for use with the amp.

Where and how do I save and then access these two savings? Are the somehow automatically selected?

In my case I want to save 100 watts for "barefoot" operation and 25 watts for amplifier operation. I've tried using Quick Memories 1-9 for bands — which works fine — and Quick Memories  M1 and M2 for the two power settings for each band — which does NOT work.

What's the right way to do this?

Richard;

You are looking in the wrong place. We made it much easier than that. Make sure you have the K3 and KPA connected with the AuxIO cable. Now go to a band on the K3 (matched on the KPA500). With the KPA in STBY, set the power setting on your K3 to whatever you want - probably 100 watts. Next tap the OP/STBY button on the KPA to put it in OPER mode. Then adjust the power setting on the KPA to the lower value for the KPA (25 watts is what you indicated).

After this when you switch the KPA in and out of OPER mode, the K3 will show you the change on the “B” display and it will automatically set the K3 power for what you want. I usually set my OPER power while transmitting so that I get what I want out of the KPA. I have two KPAs & K3s, and each needs a different TX level to drive the KPA to full power.

Hope this helps!

Jack, W6FB
