Mike, What is the voltage of your power supply? If it is 13.8 volts or higher, there should be no HI CUR messages during normal operation with CAL CUR set to 3.50. If the PS voltage is low (or you have a bad power cable connection), you may see those messages at higher power settings. The K2 maintains power level, and for any given power, it will take more current if the voltage is low.
If you power supply voltage is good, but your power output is low, Hi Curr warnings are an indication of a problem. I assume the power outputs that you site are average readings on SSB - if so, that is probably OK. What do you get when you use TUNE is the real question. You may leave the CAL CUR setting at 3.50 Amps or even higher. You might see some HI CURR messages on particular bands if you run the power control all the way to max - but don't do that, just set the power to 12 watts or less and you should not see any. Yes, the CAL CUR setting will limit the power output if that current is exceeded. That is really a helpful indicator if one is running from a battery - the message tells you that the battery voltage has dropped and a re-charge may be necessary. If used in that manner, you can set the CAL CUR to any point you desire, but with an AC power source, you can run CAL CUR up to 4 amps with no problem. 73, Don W3FPR Mike-WE0H wrote: > What should I have my Current setting set at?
