KPA-1500 with KX-3/KXPA-100

Elecraft mailing list
How integrated will the KPA-1500 be with the KX-3/KXPA-100 system?

Thanks
Dave K5MWR

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.
