[Elecraft] KPA-100 Problems

[Steve Kavanagh]

A few recent units have shown problems that at least
sound similar to this one. See, for example:

These two, at least, were due to the KSB2 ALC circuit
having insufficient attenuation range to control the
output of K2/100's with above-average overall transmit
gain on the lower bands.  The fix involves adding a
resistor and changing another in the KSB2.  Gary
Surrency at Elecraft was able to provide me the
necessary details.
