Connected to a dummy load, I do not get a HI CUR message at 5W. When
I crank up the power to 15W, I get the HI CUR message at first, then
it goes away.
Jason: It's probably not that the HI CUR situation "goes away." The
power is likely responding to the HI CUR by resetting itself to a lower
level. However, it is not uncommon for the HI CUR to occur at 15w with
the default limit setting of 2.5amps. You can check the current draw
using DISPLAY to see if it exceeds the 2.5amp limit just before the HI
CUR state arises. It is not likely to exceed 3.25, however. So, once
you get a decent antenna going, raise the HI CUR limit to 3 or 3.25
amps and enjoy.
My K2 has the HI CUR setting at 2.5 amps (default). Maybe I'll try
again with a higher value as suggested. I was getting the HI CUR
message most of the time when hooked up to a yagi at my club's
station. I'm not sure what the SWR of that antenna is, tho I wouldn't
be surprised if it's over 1.5:1. I set the power there to 5W, and hit
my CQ message and was getting HI CUR a lot of the time.
Well, that remains to be seen just what the swr of that yagi was. You
have a lot more faith than I have. In any event, if you can drive your
dummy load to 15w with the HI CUR set to 3.25 amps, then you're most
likely just fine. Give that a try. You can monitor the situation
using the K2's current meter which shows when you hit DISPLAY. If
the rig is drawing much more than 3.25 at 12-15w, you may have other
problems. This is easy enough to check out.
