Only, my (metered) SWR meter uses just ONE pickup loop, I switch terminating 50 ohm resisistor and take-off ends and use the single loop for BOTH "FWD" and "REF", with a physical switch--my thinking was it would keep the device more "balanced" using the same pickup... A toroidal pickup samples the current at one point. Knowing the current at one point tells you absolutely nothing about SWR. Hi, Cecil - I think he thinks his toroid is a directional coupler. John |

But it is a current transducer, not a directional coupler. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
