[Elecraft] KPA1500 Faulting for High SWR inappropriately

[David F. Reed]

Lou,

I appreciate the suggestion, but it is with a K4D, properly cabled, used 
to work fine, and does it on some bands but not others... changed the 
delay to 15ms and still does it... Also seems to depend on band; for 
example, does it on 10m, not on 12m...

Also, below, I said 2 SWR meters; I meant 3...

I think (but check your manual) that unless you’re using the KPA1500 with a K3 or K4 without the 15-pin Elecraft interface cable, you’ll want at least 10ms of delay to avoid that. I had that issue with a K4 and a PGXL. Default on the K4 is 8ms and the PGXL needed 10ms.
