AH-4 Tuner

image_pdfimage_print

The AH-4 tuner by Icom is a great, wide-range, remotely-operated tuner. Unfortunately the Icom manual is very sparse and only suggests a very basic way in which to use the tuner (wire hanging out of “output” terminal, other end stuck into “ground”). The described installation will work, but it’s possible to get high-end, top performance from this tuner by using it in a slightly different way.
