[Elecraft] KPA-1500 with KX-3/KXPA-100

[Ignacy]

If KPA1500 uses LDMOS without too much feedback, KX3 may be able to drive
KPA1500 directly by removing the attenuator.   

Expert 1.3k-fa is sold in the US with limited gain due to FCC regulations,
but individually, each one can be modified legally by removing the
attenuator.  With the Expert is does not invalidate the warranty. My
modified Expert needs from 5 to 8 W for a KW so KX3 drives it perfectly.  

Each extra stage increases distortions and adds cables. So doing it directly
is beneficial if it can be done.
