Yes, that is a consequence of not driving the K2 into the ALC region.
The overall Tx gain of the K2 varies from band to band, and normally the
internal ALC takes care of flattening it out. When operating AFSK data

My chart in the ARRL Handbook says RG-174 has a dielectric breakdown
voltage of 300 volts RMS. So in theory, it will handle 1800 watts at an

25 watts myself. I like to see a larger safety factor where

Well, that shows that it ought to be OK from the voltage breakdown
perspective, but consider current carrying capability or self heating of
that little bitty center conductor too. It might be limiting.
If you allow it an amp, 50 watts. Two amps, 200 watts. At 100 watts of
course, 1.414
Well, according to the wire tables, the 26 gauge center conductor can
safely handle about 350 to 400 milliamperes, depending on how you
interpret the safety factors. The center conductor is certainly not
operating in open air, so the best figure is probably the one used for
