Bob and Vic make excellent observations about needing to measure TRUE 'peak'
output.
One way you can do that with the K2 itself is to switch the bargraph to ALC
mode (press/hold RF/ALC). Now the bargraph will show you when you've hit
full power output as set by the POWER control and the ALC kicks in to turn
down the level. It reads backwards in this mode, so you should see at least
one bar on the extreme *right* flicker on voice peaks. On some bands (e.g.
40) you'll probably see several bars light up, indicating more ALC action.
But as long as the right hand bar is flickering, your K2 is making all the
requested by where you have the POWER control.
If one bar doesn't flicker, you can figure out how close you are. Just try
setting the POWER control below 100 watts. For example, if you don't get a
flicker at 100 watts, try 90. If the first bar flickers at 90, then you're
hitting at least 90 watts PEP.
