Measure your current using a suitable incandescent light bulb brought to maximum brightness, about 50p's worth from Halfords. 73 es GL Pete M0FMT GQRP#15097.in IO91UX -------------------------------------------- On Wed, 2/11/16, Steve wrote: Subject: LF: Re: SWR Bridges To: rsgb_lf_group@blacksheep.org Date: Wednesday, 2 November, 2016, 18:12 Many thanks to all of those taking the time to reply to my inquiry. It seems that results vary depending upon what meter is being used but it sounds as though only a few are having reliable / accurate results. I normally use the scope match and call it the 'most valuable piece of gear in my shack' but was curious about suggesting the use of an HF SWR bridge for those that do not yet have such a thing, and if it would be a reliable method of matching an antenna. In some cases 'yes', but it seems, in most cases, may be unreliable and only lead to confusion.
