I Though it was 52 Ohms ? WA6VAB Ray K3 #3824

Meaning they provide an indication in terms of ratio of one value of voltage to another value of voltage. Thus better described as VSWR indication. As to measurement of power, most all are calibrated to operate in a 50 ohm circuit. Departure from 50 ohms, where one uses the power indication post tuner, will yield an error which is sometimes significant, in the power indication. 73 Bob, K4TAX Message: 10 Date: Tue, 18 May 2021 08:44:01 -0700 From: Tom Azlin W7SUA<t...@w7sua.org> To:elecraft@mailman.qth.net Subject: Re: [Elecraft] Funny K4 Story Message-ID:<aefcac35-9173-0eb2-3ee9-2f83aabd1...@w7sua.org> Content-Type: text/plain; charset=utf-8; format=flowed I have an external meter on each of my antenna feedlines so I know the actual SWR for each antenna. Also see a difference in the reported power out on my (still) K3 versus the power reported on the external SWR/PWR meter.
