You will probably have to find the correct value by trial and error. I would recommend setting CAL CUR to 4.0 (which conforms to the 'at least 3.5' instruction) - or even more and then lower it one step at a time until the message re-appears - more likely on 10, 12 or 15 meters. The actual setting will depend heavily on your power supply voltage - lower PS voltage requires a higher CAL CUR setting.

Once set in that manner, it serves as a quick indicator that the power should be reduced - because the SWR is higher than it should be, or the power supply voltage has dropped, etc.
This is normally not an indication of a K2 problem.

----- Original Message ----- On my K2/100 I have set the HI CUR to 3.5 but get warnings on some higher bands. The manual says HI CUR should be set to at least 3.5. Can anyone recommend what a typical value should be and what value I should not go beyond.
