I'm using a LP100A vector wattmeter http://www.telepostinc.com/lp100.html with dual coupler option Beside the standard coupler I have the RF sensor LPC6 (.1-20MHz ,1KW) which is not listed on the we
Hi Stefan, a HF SWM meter should work on 475 kHz, but most of these use a directional coupler made of one or two pieces of wire parallel to the wire that carries the TX signal.. This make them rather
er ......an SWR "meter" will tell you nothing about resonance :-)) Alan G3NYK Hi MF, Did someone try to use a normal HF SWR meter on 630m? They are specificated down to 1800 kHz of course but what ab
Stefan; Where you want to have near perfect match in BC business, to long runs of common 50 ohm line a bridge is used. A hot bridge makes things quick and easy-Bob > Date: Sun, 29 Sep 2013 23:08:28 +

Does it not? I suggest to do a test: Use a MF antenna (on 160m, for this test), resonate it to the TX frequency by using a variometer. Then use a ferrite transformer to match the impedance to 50 Ohm.

No it does not.....BUT I did not imply that, with knowledge, it can not yield useful information....Too many think 1:1 swr means resonance. A friend of mine used to do a demo at clubs where he had a
