I am a bit mystified by the reports of low power on 30M. I have K2 #4028
and bought my KPA-100 at the time I purchased my K2. Barefoot on 30M, I have
15w out (measured) and QRO a good solid 100W (measured). If I choose to
observe power out in TUNE, the K2 will cut the power to around 55W, but
coming out of tune and closing the key will get me a good solid 100W. I have
not experienced a problem with overcurrent. I wonder what has changed in the
more recently delivered KPA100s to cause the problem?
Just for grins, I switched in the dummy load and on 30M with the POWER
control at full throttle, I can bump 3.5 amps according to the K2 current
display. And as reported above, a rock solid 100W.
Just curious.
Jim, W4ATK
