Good suggestion. If a 2-meter module is installed, as is the case with mine, I wonder if the automated calibration using the KX3 Utility flies through all the bands including that one? I wouldn't want to start pressing buttons and find out the wrong way. The reason for my concern is that I only have one dummy load, the MFJ-260C. I'd like to get ahold of the Oak Hills Research RFL-100 mentioned here recently, but unfortunately when I tried to order one a few days ago his website said all sales had been suspended indefinitely due to COVID. I guess I can either scrounge another dummy load, or do the calibration band-by-band manually.
Re Mark's questions about the Bird 43 and slugs, I do have an older Bird that I don't trust a great deal, but this one was bought new about a year ago, and the slugs are the same vintage or newer. I can try them out with other radios.
As for Walter's point about the ATU, the results are mighty odd. I just set the KX3 to 40 meters with 15 watts out, appropriate slug in the Bird 43, set ATU to bypass and started keying. The power out dropped to about 5w. I then set ATU to auto and tapped the ATU Tune button. With the radio still set to 15w out, the Bird now peaked at about 25w! Is it plausible that antenna tuning activity within the KX3 could actually increase the TPO by ~5x? Or does that cast even more suspicion on the Bird?
