will be a temporary antenna while I build the antenna farm here at the

My KPA-500 watt meter and my Palstar watt meter read about the same at the
higher power readings. But at the 100 watt and lower ranges there is a
significant difference. My question is which is the more correct reading at the
lower ranges, the Elecraft or Palstar. If I want to calibrate

Hi Ray,
Thanks or your response. I have found that on 20 meters my K3 displays a high

If you've run the TX gain calibration, and that worked properly, it sounds more
like you have an actual load problem. Which would cause high current.
Is the high current warning happening both with a known good 50 ohm load
connected to the K3 and with the antenna?

The high current warning on 20 meters happens with either a dummy load or my
antenna's through an antenna tuner. It happens only on 20 meters and over 80
watts. If I set the K3 for more than 80 watts the output of the K3 goes into
oscillation evident on the K3 watt meter. Lower than 80 watts
Sounds like RF. Are all the pl259's and other cabling tight etc?

Maybe you can put a scope across the dummy load and calibrate your power
output that way. That has worked for me.

I hope you have a 4:1 Unun at the antenna. I am going to play with one
of these antennas at 31ft and 43ft for an antenna down at J6 as they are
light and easy to take and seem to work on all bands. It would make an

Hi,
Yeah, really. Exceedingly dumb, but I figure I'd better ask anyway.
I have a K2/100. Naturally, this means it has the SO239 antenna connector on
the 100-watt amp, It also, of course, still has the BNC connector from the
original assembly of the original K2. So, with the KPA100 integrated,
Buddy,
I believe you would have to physically disconnect the RF and power connections
on the main board of the K2, as well as unhooking the connection on the front
panel that goes to the integrated KIO interface before the original K2 BNC will

Yes, it does matter - that is why there is a boot for the QRP BNC

When the KPA100 is installed, the antenna output must be from the SO-239

Failure to do so will result in incorrect power control from the K2, and
