For some reason this comes up often on ham lists. The SWR meter measures the match AT THAT point in the network. The SWR varies along the feedline (which is why 1/2 wave feed sections are often desired, so you can get an accurate antenna feed point reading).
You can take ten different meters, each a meter apart from each other on the cable and see ten different measurements. The most important reading is the one AT the transmitter (or at input of the tuner, if used); the rest are superfluous information; nice to know but not critical. 73, Rick wa6nhc -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of pastor...@verizon.net Sent: Wednesday, November 13, 2013 9:25 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Internal SWR Readings Hi, it's Mark Griffin, KB3Z. I was wondering how reliable the SWR reading is on the K3? I have an external SWR/Power Meter hooked up between my K3, Antenna Tuner and my Amp. Sometimes there seems to be some major differences between the K3 and the External Meter. And it always is the fact the the K3 gives a higher reading then the External meter. Has anyone experienced this also and if so can one Sync up there Internal SWR meter on the K3? Thanks!
