Jon,

I would be suspicious that the wattmeter in the KAT2 is not properly balanced and calibrated for forward power. The K2 uses the DC output from that wattmeter to tell the MCU what the actual output power is, but if it is not properly calibrated, that DC voltage will not be correct and the K2 will not develop the expected power output.

Review the Nulling (balance) procedure in the KAT2 manual, and then after doing that procedure, set the forward power calibration to agree with your external meter - of course that must be done with a good non-reactive 50 ohm dummy load attached.

I was starting to remember that. According to my meter, I see 5W, though. Any setting for the tune level, or should I worry about that?

Main thing is, I don't have some kind of issue that might have lowered my power output during normal operation. Sounds like a no.

My next concern is how to check or adjust the ALC or mic gain levels, to see if I'm driving the radio properly... But that's probably another thread, as well as the question "has any K2 updates come out since I was last here?"

Thanks...

Jon,

I assume you have the KAT2 installed and set for AUTO.
If so, the K2 reduces the power to 2 watts during tuning of the ATU.

Yes, turning the power knob even a little will bring up the full power setting - that is normal.

Hello all...

Long time no mailing list... I have a K2, with many addons, SSB, etc, have not done much ham radio the past several years, but have dusted things off and am working a few out there again.

Something I've noticed, is that when I use the tune button, to auto tune the antenna tuner, I see about 5W output, no matter what the setting is. If I touch the power knob, it instantly jumps to the set power level. If I have the display set to read volts and amps, I get the set power level when I tune.

Is this normal behavior, or do I have some kind of ALC level issue? Would this affect my output on SSB, (or any mode) leaving me at 5W despite my power knob setting? If this is a problem, was there a solution?

As I type this, I almost feel I remember something about this, perhaps a tune only power reduction in the SW, to protect things? Not sure...

I don't even remember what my FW version is,   will look later.

TIA...
