Title: EFJ KW Matchbox relay noise Post by: kb9r on March 20, 2014, 07:46:26 PM Hello,
Has anyone found a way to reduce the "clang" when the t/r relay is activated in the matchbox? Maybe a slab of metal under the relay to keep the cabinet from amplifying the "clang"?

I've never tried that, in the spirit of full disclosure :) Title: Re: EFJ KW Matchbox relay noise Post by: WD8KDG on March 20, 2014, 10:27:46 PM Hello, Has anyone found a way to reduce the "clang" when the t/r relay is activated in the matchbox?

Thanks, Joe - KB9R Clangs & Clunks are the sounds of heavy metal ;D Much better than rogerbeepers & reverbs. ::) Craig, Title: Re: EFJ KW Matchbox relay noise Post by: Steve - K4HX on March 21, 2014, 12:28:46 AM A relay clunk with a some reverb added is AWESOME!

If your just clunks that is a good thing but if it bothers you some acoustical isolation in the mount would tame it down. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
