I have Expert 1.3k that I use with KX3 for > 1 KW.
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! 73, ... Joe, W4TV On 12/30/2016 11:07 PM, Ignacy wrote:
With a little work, KPA500 can be a KW amp while losing weight. This is by using LDMOS and a commercial PS. But then KAT500 would have to be beefed up to KAT1000. I have Expert 1.3k that I use with KX3 for > 1 KW. The Expert is 21 lbs (lighter than Elecraft) with a 3:1 tuner + 4 antenna switch and automatic 110/220V switching; KPA500/KAT500 would be 35 lbs + cables. Also without dealers markup, the no-ATU version is not that much expensive than KPA500. But the Expert needs Elecraft refinement. One KW is great when working portable as DX. Everybody responds even with impromptu antennas.
