Having set Rx Equaliser desired settings on the KX3, is there any way to
switch to "flat" & back during operation?

1) send a serial command ^on1 via the USB port. This is what the KPA1500
Utility does. The amp can process a few commands like this when “off”. The
KPA1500 Remote program can also do this, via the USB connector. ^on0 turns the
amp off.
2) supply 12v DC to a rear panel RCA connector. This can

Is there any way to turn it on/off alone, with no need to turn on/off the

For example i want to turn on K3, but want to have KPA1500 off, is there
any way to do that?

I have been using 4 of these switches to share one amplifier between two K3s in

I did not go all the way to 50Mhz. You comment indicated a knee at 21 Mhz,
I did not see that. I saw a linear rise in SWR with frequency. At 28Mhx,
the resistive component was still close to 50 ohms. It looks like a fixed
inductance or capacitance that likely could be compensated

While I suspect that voltage requirements for the KX3 are similar to those of

And I agree with Don. The underlying issue here is why is the power supply
voltage so low? The KX2 (or KX3) shouldn’t draw more than around three Amps

That is too much voltage drop. Check all your power connections to be
sure they are tight. If the power supply terminals rotate even a little
bit, open the power supply and tighten the terminals securely.

Set the display to show the power supply voltage and watch it while you
transmit. The transmitter requires a voltage over 11 V for more than 5 W.
If the voltage is dropping below 11 V, that is the problem.

Hi folks,
I'm running FT8 with a KX2 powered by a power supply. The rig
keeps folding back from 10-12 watts to 5 every time and it's barely even
warm. I'll set it to 12W for instance, it'll transmit fine at that
level but when done cut back to 5w. I don't transmit often enough for it
Thanks Don. I just wanted to make sure.
I have one more test to do - to try a new cable. The ohmmeter said the
old cable was fine but I'm having a cable sent.
