"Let's wait for someone who knows how SWR measurement is done in K3 firmware."
I'll add that I asked because I chased a similar problem before I got my K3. Two pieces of good test equipment found no trouble. But the lash-up I was using caused trouble when power was applied. 73, Dick, n0ce ----- Original Message ----- From: "Jörg Rüschenschmidt" <dl...@rrdxa.eu> To: "Richard Fjeld " <rpfj...@embarqmail.com> Cc: elecraft@mailman.qth.net Sent: Monday, September 23, 2013 2:30:33 PM Subject: AW: [Elecraft] K3 internal SWR meter Richard, If I use a dummy load or perfect tuned antenna (SWR 1:1.1) the problem is not recognized. I think SWR measurement will done in KAT3 if this unit is installed, even in bypass mode. Maybe this issue is related to users with KAT3 only. Don, W3FPR assumes it could be a software problem.
