Anyone have any knowledge of these units? I have a roof feed thru unit with azimuth scale and wheel, along with 4 loops marked A-B-C & D. Probably vehicle mounted. Can take pix, and unit will probably be for sale. Thanx Lloyd Godsey KK7IZ kk7iz at cox.net 480-620-7145 http://www.lloydsdipsydumpster.com/ http://antiqueradioarchives.com/
