Please do a KPA1500

Since I sometimes bring my station to the Caribbean, one of the main reasons
that I switched to the Elecraft line was for the size and weight. I have a
KPA500 and an it is an awesome amplifier but I would like a little more
power at times. I considered the Expert 1.3k that many with similar needs
use but I have not swapped my Elecraft due to the reasons that W4TV
mentioned below. It may not be practical for Elecraft to manufacture a small
lightweight KPA1500 at an affordable price however perhaps a KPA750 or
KPA1000 could be. I would certainly be interested in one of these. I read
many posts on this list saying that 3 or 4dBs make almost no difference. I
did a quick search of my last 200,000+ QSOs and could not find any of the
stations making this claim in my logs so I wonder how active they are on HF.

The Expert 1.3K also violates the 15 dB gain limitation rule and is a
real garbage generator. Expert's own test data in their application
for FCC approval showed IMD at -27 dB at 800 W! For your 1 KW, each
of the IMD products are probably around .5W and I'd hate to even
think about the IMD level at 1.3 KW!

I think a KPA1000 would be pretty popular if priced appropriately. I
love my KPA500, but a little extra oomph would be nice now and then.

So buy another KPA500 and combine them. Easy peasy.
